ASTM D7678-2011 用中红外激光光谱法和溶剂萃取测试水和废水中石油烃总量(TPH)的标准试验方法
简介:The presence and concentration of total petroleum hydrocarbons, as well as oil and grease, in domestic and industrial wastewater is of concern to the public because of its deleterious aesthetic effect and its impact on aquatic life. Regulations and standards have been established that require monitoring of total petroleum hydrocarbons as well as oil and grease in water and wastewater.1.1 This test method covers the determination of total petroleum hydrocarbons (TPH) in water, and waste water, that are extractable from an acidified sample with a cyclic aliphatic hydrocarbon (for example cyclohexane), and measured by IR absorption in the region of 1370 -1380 cm-1 (7.25 -7.30 microns). Polar substances are removed by clean-up with Florisil. 1.2 The method also considers the volatile fraction of petroleum hydrocarbons which is lost by gravimetric methods that require solvent evaporation prior to weighing, as well as by solventless IR methods that require drying of the employed solid phase material prior to measurement. Similarly, a more complete fraction of extracted petroleum hydrocarbon is accessible by this method as compared to GC methods that use a time window for quantification, as petroleum hydrocarbons eluting outside these windows are also quantified. 1.3 This method defines oil and grease in water and wastewater as that which is extractable in the test method and measured by IR absorption in the region of 1370-1380 cm-1 (7.25 x2013; 7.30 microns). 1.4 This method covers the range of 0.5 to 1000 mg/L and may be extended to a lower or higher level by extraction of a larger or smaller sample volume collected separately. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM A1038-2013 用超声波接触阻抗法进行便携式硬度测试的标准试验方法
简介:4.1x00a0;The hardness of a material is a defined quantity having many scales and being dependent on the way the test is performed. In order to avoid the creation of a new method involving a new hardness scale, the UCI method converts into common hardness values, for example, HV, HRC, etc. 4.2x00a0;The UCI hardness test is a superficial determination, only measuring the hardness condition of the surface contacted. The results generated at a specific location do not represent the part at any other surface location and yield no information about the material at subsurface locations. 4.3x00a0;The UCI hardness test may be used on large or small components at various locations. It can be used to make hardness measurements on positions difficult to access, such as tooth flanks or roots of gears. 1.1x00a0;This test method covers the determination of comparative hardness values by applying the Ultrasonic Contact Impedance Method (UCI Method). 1.2x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4327-2011 用化学压缩离子色谱法测试水中阴离子的标准试验方法
简介:Ion chromatography provides for both qualitative and quantitative determination of seven common anions, Fx2212;, Clx2212;, NO2x2212;, HPO4x2212;2, Brx2212;, NO3x2212;, and SO4x2212;2, in the milligram per liter range from a single analytical operation requiring only a few milliliters of sample and taking approximately 10 to 15 min for completion. Additional anions, such as carboxylic acids, can also be quantified. Note 28212;This test method may be used to determine fluoride if its peak is in the water dip by adding one mL of eluent (at 100x00D7; the concentration in 8.3) to all 100-mL volumes of samples and standards to negate the effect of the water dip. (See 6.3, and also see 6.4.) The quantitation of unretained peaks should be avoided. Anions such as low molecular weight organic acids (formate, acetate, propionate, etc.) that are conductive coelute with fluoride and would bias fluoride quantitation in some drinking waters and most wastewaters. The water dip can be further minimized if measures are taken to remove carbonic acid which remain in the eluent after suppression using carbonate based eluents. There is no water dip if hydroxide eluents are used. Anion combinations such as Clx2212;/Brx2212; and NO2x2212;/NO3x2212;, which may be difficult to distinguish by other analytical methods, are readily separated by ion chromatography.1.1 This test method covers the sequential determination of fluoride, chloride, nitrite, ortho-phosphate, bromide, nitrate, and sulfate ions in water by suppressed ion chromatography. Note 18212;Order of elution is dependent upon the column used; see Fig. 1.

ASTM D5030/D5030M-2013a 采用测试井中水置换法就地测定土壤和岩石密度的标准试验方法
简介:5.1x00a0;These test methods are used to determine the in-place density of compacted materials in construction of earth embankments, road fills, and structure backfill. For construction control, the test methods can be used as the basis for acceptance of material compacted to a specified density or to a percentage of a maximum density determined by a standard laboratory test method such as determined from Test Methods D698 or D1557, subject to the limitations discussed in 1.4. 5.2x00a0;These test methods can be used to determine in-place density of natural soil deposits, aggregates, soil mixtures, or other similar material.Note 1x2014;The quality of the result produced by these test methods are dependent on the competence of the personnel performing them and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of these test methods are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors. 1.1x00a0;These test methods cover the determination of the in-place density of soil and rock using water to fill a lined test pit to determine the volume of the test pit. The use of the word x201c;rockx201d; in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. [75 mm]. 1.2x00a0;These test methods are best suited for test pits with a volume between approximately 3 and 100 ft3 [0.08 and 2.83 m3]. In general, the materials tested would have maximum particle sizes over 5 in. [125 mm]. These test methods may be used for larger sized excavations if desirable. 1.2.1x00a0;This procedure is usually performed using circular metal templates with inside diameters of 3 ft [0.9 m] or more. Other shapes or materials may be used providing they meet the requirements of these test methods and the guidelines given in Annex A1 for the minimum volume of the test pit. 1.2.2x00a0;Test Method D4914 may be used as an alternative method. Its use, however, is usually only practical for volume determination of test pits between approximately 1 and 6 ft3 [0.03 and 0.17 m3]. 1.2.3x00a0;Test Method D1556 or Test Method D2167 is usually used to determine the volume of test holes smaller than 1 ft3 [0.03 m3]. 1.3x00a0;The two procedures are described as follows: 1.3.1x00a0;Procedure Ax2014;In-Place Density and Density of Total Material (Section 12). 1.3.2x00a0;Procedure Bx2014;In-Place Density and Density of Control Fraction (Section 13). 1.4x00a0;Selection of Procedure: 1.4.1x00a0;Procedure A is used when the in-place density of total material is to be determined.

ASTM F1407-2011 测定化学防护服装材料抗液体渗透性的测试方法 - 渗透杯法标准试验方法
简介:This test method establishes a standard procedure for rapidly (in 1 h or less) determining the chemical resistance of specimens of protective clothing materials. This test method can be used to rank materials as to their suitability for use with liquids of known or unknown composition. The breakthrough detection time, permeation rate, or cumulative permeation can be used to identify protective clothing materials that are more likely to limit potential exposures to chemicals. Longer breakthrough detection times and lower cumulative amounts permeated and permeation rates are characteristics of materials that are better barriers to the test chemical. In general this test method is less sensitive than Test Method F739 coupled with sensitive analytical procedures. In cases where the chemical of concern is highly toxic and contact of even a very small amount with the skin may be detrimental to health, the permeation cup method is not recommended. Use Test Method F739. Upon permeating the clothing material, the chemical must evaporate in order for a weight loss to occur and permeation to be detected. Consequently, the test method may not be applicable for chemicals having low volatility (that is, vapor pressure). The vapor pressure below which this test method is not applicable has not been determined. A procedure for assessing volatility is described in Section 10. The results of this test method are highly dependent on the test temperature. If the objective is to compare different clothing materials, all tests shall be conducted at the same temperature (x00B1;3x00B0;C). 1.1 This test method measures the barrier effectiveness of a specimen of protective clothing upon continuous contact with a liquid. 1.1.1 Procedure A8212;For use when a value for the cumulative amount of chemical permeated in 1 h is desired. 1.1.2 Procedure B8212;For use when breakthrough detection time and permeation rate values are desired. 1.2 Although not addressed herein, the effect of the test chemical on the clothing material can be determined by comparing the weight or other physical properties of the specimen before and after the permeation test. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 2.

ASTM D3907/D3907M-2013 使用微活性试验法测试流化床催化裂化(FCC)催化剂的标准试验方法
简介:5.1x00a0;The microactivity test provides data to assess the relative performance of FCC catalyst. Because results are affected by catalyst pretreatment, feedstock characteristics, test equipment, and operating parameters, adherence to this test method is a prerequisite for correct interpretation of results. Apparatus, test conditions, and analytical procedures actually used should closely resemble those described in this test method. 5.2x00a0;Caution should be used in interpreting results above 80 weight % conversion due to the significance of overcracking. 1.1x00a0;This test method covers determining the activity of equilibrium or laboratory-deactivated fluid catalytic cracking (FCC) catalysts, or both. This is evaluated on the basis of weight percent conversion of gas oil in a microactivity unit. The selectivity of FCC catalysts can be determined using Test Method D5154. 1.2x00a0;The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7369-2011 用间接拉伸测试法测定沥青混合料弹性模数的标准试验方法
简介:Resilient modulus can be used in the evaluation of materials quality and as input for pavement design, evaluation and analysis. With this method, the effects of temperature and load on resilient modulus can also be investigated. Note 18212;The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Practice D3666 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with D3666 alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.1.1 This test method covers procedures for preparing and testing laboratory-fabricated or field-recovered cores of bituminous mixtures to determine resilient modulus values using a repeated-load indirect tension test. 1.2 The values stated in SI units are regarded as the standard. Values in parentheses are for informational use. 1.3 A precision and bias statement for this standard has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

简介:5.1x00a0;This test method is used to determine the effect of exposure to elevated temperatures on the bond strength of combinations of magnet wire insulations and electrical insulating varnishes. The results are used as a guide for the comparison and selection of varnishes and combinations of varnishes and magnet wire insulation for specific applications. Test Methods D1932 and D3251describe additional tests for determining the thermal endurance of insulating varnishes. A comprehensive evaluation of thermal characteristics includes a comparison of the thermal endurance determined in these different ways. 5.2x00a0;This test method is useful for research and product qualifications purposes. 1.1x00a0;This test method covers the determination of the thermal endurance of electrical insulating varnishes alone or in combinations with magnet wire insulation. Changes in the helical coil bond strength are used as the test criteria. The coils are made from bare aluminum or copper wire, or from film- or fiber-insulated magnet wire. 1.2x00a0;The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.Note 1x2014;There is no similar or equivalent IEC standard. 1.3x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM D5984-2011 利用显色指示剂滴定法测试新的和已用过的润滑剂碱值的半定量现场试验法的标准试验方法
简介:New and used petroleum products can contain basic constituents that are present as additives or as degradation products formed during service. The amount of these additives in an oil can be determined by titrating against an acid. The base number is a measure of the amount of basic substance in the oil, always under the conditions of the test. A decrease in base number is often used as a measure of lubricant degradation, but any condemning limits must be empirically established. This test method uses reagents that are considered less hazardous than most reagents used in alternate base number methods. It uses pre-packaged reagents to facilitate base number determinations in the field where scientific equipment is unavailable and quick results are at a premium. Note 18212;Results obtained by this test method3 are similar to those obtained by Test Method D 2896. 1.1 This test method covers a procedure for determining the basic constituents in petroleum products in the field or laboratory using a pre-packaged test kit. The test uses a micro-titration resulting in a visual end point facilitated by a color indicator.1.1.1 This test method covers base numbers from 0 to 20. It can be extended to higher ranges by diluting the sample or by using a smaller sample size; however, the precision data were obtained for base numbers up to 20.1.2 This test method can be used to indicate relative changes that occur in an oil during use under oxidizing conditions. Although the test is performed under closely specified conditions with standardized reagents, the test method does not measure an absolute basic property that can be used to predict performance of an oil under service conditions. No general relationship between bearing corrosion and base number is known.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D5837-2012 用高性能液体色谱法(HPLC)测试电绝缘液中呋南化合物的标准试验方法
简介:Furanic compounds are generated by the degradation of cellulosic materials used in the solid insulation systems of electrical equipment. Furanic compounds which are oil soluble to an appreciable degree will migrate into the insulating liquid. High concentrations or unusual increases in the concentrations of furanic compounds in oil may indicate cellulose degradation from aging or incipient fault conditions. Testing for furanic compounds may be used to complement dissolved gas in oil analysis as performed in accordance with Test Method D3612. 1.1 This test method covers the determination in electrical insulating liquids of products of the degradation of cellulosic materials such as paper, pressboard, and cotton materials typically found as insulating materials in electrical equipment. These degradation products are substituted furan derivatives, commonly referred to as furanic compounds or furans. This test method allows either liquid/liquid or solid phase extraction (SPE) of the furanic compounds from the sample matrix followed by analysis for specific furanic compounds by HPLC or direct injection for analysis of specific furanic compounds by HPLC. 1.2 The individual furanic compounds that may be identified and quantified include the following: 5-hydroxymethyl-2-furaldehyde furfuryl alcohol 2-furaldehyde 2-acetylfuran 5-methyl-2-furaldehyde 1.3 The direct injection method generally has a higher limit of detection, especially for furfuryl alcohol. Greater interference for furfuryl alcohol may be expected when using the direct injection method as opposed to extraction methods. 1.4 This test method has been used to successfully test for furanic compounds in mineral insulating oil, silicone fluid, high fire point electrical insulating oils of mineral origin, askarels, and perchloroethylene-based dielectric fluids. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

简介:The impact strength of PVC profiles relates to suitability for service and to quality of processing. Impact tests are used for quality-control purposes and as an indication that products can withstand handling during assembling, installation, or in service. Results obtained by use of this test method are able to be used in two ways: As the basis for establishing impact-test requirements in product standards, and To measure the effect of changes in materials or processing. 1.1 This test method covers the determination of the energy required to crack or break rigid poly(vinyl chloride) (PVC) profile under specified conditions of impact by means of a falling weight. 1.2 This test method is used either by itself or in conjunction with other methods for measuring PVC product toughness. 1.3 Because of the wide variety of profile sizes and shapes and the wide variety of manufacturing procedures and field abuse, this test method does not correlate universally with all types of abuse. Therefore, correlations must be established as needed. 1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard. 1.5 The values stated in inch-pound units are to be regarded as the standard. Note 18212;There is no known ISO equivalent to this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

简介:This European Standard is applicable for internally coated cylindrical aluminium tubes, mainly used for the packing of pharmaceutical, cosmetic, hygiene, food or other household products. The internal coating is used as a barrier and should avoid any contact between aluminium and the product. This standard defines the copper sulphate method to detect the electrolyte conductivity as one criterion for the quality of the internal coating. The electrolyte conductivity of the internal coating is only one criterion for evaluation of the quality of an internal coating. It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint on possible reactions between the aluminium tube and the product. The electrolyte conductivity should never be used as the sole criterion for quality evaluation of the internal coating, but always with other parameters e. g. film thickness, acetone and/or ammonia resistance and of course results of enhanced stability studies.

It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint on possible reactions between the aluminium tube and the product. The electrolyte conductivity should never be used as the sole criterion for quality evaluation of the internal coating, but always with other parameters e. g. film thickness, acetone and/or ammonia resistance and of course results of enhanced stability studies.

ASTM D6228-2010 通过气相色谱和火焰光度法测试测定天然气和气体燃料中的硫化物的标准试验方法
简介:Many sources of natural gas and petroleum gases contain varying amounts and types of sulfur compounds, which are odorous, corrosive to equipment, and can inhibit or destroy catalysts used in gas processing. Their accurate measurement is essential to gas processing, operation, and utilization. Small amounts, typically, 1 to 4 ppmv of sulfur odorant compounds, are added to natural gas and liquefied petroleum (LP) gases for safety purposes. Some odorant compounds can be reactive and may be oxidized, forming more stable compounds having lower odor thresholds. These gaseous fuels are analyzed for sulfur odorants to help ensure appropriate odorant levels for safety. This test method offers a technique to determine individual sulfur species in gaseous fuel and the total sulfur content by calculation. Gas chromatography is used commonly and extensively to determine other components in gaseous fuels including fixed gas and organic components (see Test Method D1945). This test method dictates the use of a specific GC technique with one of the more common detectors for measurement.1.1 This test method covers the determination of individual volatile sulfur-containing compounds in gaseous fuels by gas chromatography (GC) with a flame photometric detector (FPD) or a pulsed flame photometric detector (PFPD). The detection range for sulfur compounds is from 20 to 20 000 picograms (pg) of sulfur. This is equivalent to 0.02 to 20 mg/m3 or 0.014 to 14 ppmv of sulfur based upon the analysis of a 1-mL sample. 1.2 This test method describes a GC method using capillary column chromatography with either an FPD or PFPD. 1.3 This test method does not intend to identify all individual sulfur species. Total sulfur content of samples can be estimated from the total of the individual compounds determined. Unknown compounds are calculated as monosulfur-containing compounds. 1.4 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are for information only. 1.5 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM F2634-2010 通过拉力冲击法实验室测试聚乙烯(PE)熔接接头的标准试验方法
简介:This test method is designed to impart tensile impact energy to a butt fused plastic pipe specimen, record the energy to fail the specimen and plot the load over time curve of the tensile test. Energy recorded at yield and rupture and the rupture mode (brittle or ductile) are used as criteria in the evaluation of the butt fusion joint. The evaluation of the force/time curve not only makes it possible to compare different butt fusion parameters but also to evaluate the rupture mode of the specimen to determine joint integrity. Each coupon''s test results will usually be compared to test results for coupons machined from the base pipe material, un-fused. These data are also useful for qualitative characterization and for research and development. For many materials, there may be a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material specification before using this test method. Tensile properties may vary with specimen preparation and with speed and environment of testing. Consequently, where precise comparative results are desired, these factors must be carefully controlled. It is realized that a material cannot be tested without also testing the method of preparation of that material. Hence, when comparative tests of materials per se are desired, the greatest care must be exercised to ensure that all specimens are prepared in exactly the same way, unless the test is to include the effects of specimen preparation. While care must be taken to secure the maximum degree of uniformity in details of preparation, treatment, and handling, the exact dimensions of the test specimens are entered into the Data Acquisition System (DAS) before initiating the test.1.1 This is a tensile impact test method that develops enough tensile impact energy at specific rates of strain to rupture standard tensile impact specimens of butt fused plastic pipe. It is used to determine the quality of PE butt fusion joints made in the field or in qualification testing. It can also be used to determine the optimum butt fusion joining parameters of PE materials. 1.2 This test method is applicable for testing pipe specimens with a diameter 2.37 in. (60.3mm) and larger with a wall thickness from 0.25 in. (6.3 mm) and larger. Note 18212;This test method is similar to ISO 13953. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This test method may be used alone or together with other test methods, to evaluate the quality of the butt fused joints. When this test, conducted at laboratory temperatures per 9.2, is combined with the elevated temperature, sustained pressure test in Specification D3035, both the short term and long term strength of the PE butt fusion joint will be verified. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D5628-2010 用下落投掷法(冲击锤或下落块)测试扁平硬质塑料试样抗冲击性的标准试验方法
简介:Plastics are viscoelastic and therefore are likely to be sensitive to changes in velocity of the mass falling on their surfaces. However, the velocity of a free-falling object is a function of the square root of the drop height. A change of a factor of two in the drop height will cause a change of only 1.4 in velocity. Hagan et al (2) found that the mean-failure energy of sheeting was constant at drop heights between 0.30 and 1.4 m. This suggests that a constant mass-variable height method will give the same results as the constant height-variable mass technique. On the other hand, different materials respond differently to changes in the velocity of impact. Equivalence of these methods should not be taken for granted. While both constant-mass and constant-height techniques are permitted by these methods, the constant-height method should be used for those materials that are found to be rate-sensitive in the range of velocities encountered in falling-weight types of impact tests. The test geometry FA causes a moderate level of stress concentration and can be used for most plastics. Geometry FB causes a greater stress concentration and results in failure of tough or thick specimens that do not fail with Geometry FA (3). This approach can produce a punch shear failure on thick sheet. If that type of failure is undesirable, Geometry FC should be used. Geometry FB is suitable for research and development because of the smaller test area required. The conical configuration of the 12.7-mm diameter tup used in Geometry FB minimizes problems with tup penetration and sticking in failed specimens of some ductile materials. The test conditions of Geometry FC are the same as those of Test Method A of Test Method D1709. They have been used in specifications for extruded sheeting. A limitation of this geometry is that considerable material is required. The test conditions of Geometry FD are the same as for Test Method D3763. The test conditions of Geometry FE are the same as for ISO 6603-1. Because of the nature of impact testing, the selection of a test method and tup must be somewhat arbitrary. Although a choice of tup geometries is available, knowledge of the final or intended end-use application shall be considered. Clamping of the test specimen will improve the precision of the data. Therefore, clamping is recommended. However, with rigid specimens, valid determinations can be made without clamping. Unclamped specimens tend to exhibit greater impact resistance. Before proceeding with this test method, reference should be made to the specification of the material being tested. Table 1 of Classification System D4000 lists the ASTM materials standards that currently exist. Any test specimens preparation, conditioning, dimensions, or testing parameters or combination thereof covered in the relevant ASTM materials specification shall take precedence over those mentioned in this test method. If there are no relevant ASTM material specifications, then the default conditions apply.1.1 This test method covers the determination of the threshold value of impact-failure energy required to crack or break flat, rigid plastic specimens under various specified conditions of impact of a free-falling dart (tup), based on testing many specimens. 1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibi......

简介:5.1x00a0;These test methods are used to determine the in-place density of compacted materials in construction of earth embankments, road fills, and structure backfill. For construction control, these test methods are often used as the bases for acceptance of material compacted to a specified density or to a percentage of a maximum unit weight determined by a standard laboratory test method (such as determined from Test Method D698 or D1557), subject to the limitations discussed in 1.4. 5.2x00a0;These test methods can be used to determine the in-place density of natural soil deposits, aggregates, soil mixtures, or other similar material. Note 1:x00a0;The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing. Users of these test methods are cautioned that compliance with Practice D3740 does not in itself ensure reliable results. Reliable testing depends on many factors; Practice D3740 provides a means of evaluating some of those factors. 1.1x00a0;These test methods cover the determination of the in-place density of soil and rock using a pouring device and calibrated sand to determine the volume of a test pit. The word x201c;rockx201d; in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. [75 mm]. 1.2x00a0;These test methods are best suited for test pits with a volume from 0.03 to 0.17 m3 [1 to 6 ft3]. In general, the materials tested would have a maximum particle size of 75 to 125 mm [3 to 5 in.]. 1.2.1x00a0;For larger sized excavations and soil containing larger particles, Test Method D5030 is preferred. 1.2.2x00a0;Test Method D1556 or D2167 are usually used to determine the volume of test holes smaller than 0.03 m3 [1 ft3]. While the equipment illustrated in these test methods is used for volumes less than 0.03 m3 [1 ft3], the test methods allow larger versions of the equipment to be used when necessary. 1.3x00a0;Two test methods are provided as follows: 1.3.1x00a0;Test Method Ax2014;In-Place Density of Total Material (Section 10). 1.3.2x00a0;Test Method Bx2014;In-Place Density of Control Fraction (Section 11).

ASTM A1038-2010a 用超声波接触阻抗法进行便携式硬度测试的标准试验方法
简介:The hardness of a material is a defined quantity having many scales and being dependent on the way the test is performed. In order to avoid the creation of a new method involving a new hardness scale, the UCI method converts into common hardness values, for example, HV, HRC, etc. The UCI hardness test is a superficial determination, only measuring the hardness condition of the surface contacted. The results generated at a specific location do not represent the part at any other surface location and yield no information about the material at subsurface locations. The UCI hardness test may be used on large or small components at various locations. It can be used to make hardness measurements on positions difficult to access, such as tooth flanks or roots of gears.1.1 This test method covers the determination of comparative hardness values by applying the Ultrasonic Contact Impedance Method (UCI Method). 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

简介:5.1x00a0;This fire test response standard is designed to provide a basis for estimating one aspect of the fire exposure behavior of a floor-covering system installed in a building corridor. The test environment is intended to simulate conditions that have been observed and defined in full scale corridor experiments. 5.2x00a0;The test is intended to be suitable for regulatory statutes, specification acceptance, design purposes, or development and research. 5.3x00a0;The fundamental assumption inherent in the test is that critical radiant flux is one measure of the sensitivity to flame spread of floor-covering systems in a building corridor. 5.4x00a0;The test is applicable to floor-covering system specimens that follow or simulate accepted installation practice. Tests on the individual elements of a floor system are of limited value and not valid for evaluation of the flooring system. 5.5x00a0;In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test method to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure. 1.1x00a0;This fire-test-response standard covers a procedure for measuring the critical radiant flux of horizontally mounted floor-covering systems exposed to a flaming ignition source in a graded radiant heat energy environment in a test chamber. A specimen is mounted over underlayment, a simulated concrete structural floor, bonded to a simulated structural floor, or otherwise mounted in a typical and representative way. 1.2x00a0;This fire-test-response standard measures the critical radiant flux at flame-out.

简介:4.1x00a0;General purpose and many specialty rubbers will undergo ozone cracking when exposed to ozone containing atmospheres, when the test specimens or actual use products are under a certain degree of tensile strain. Certain additives such as antiozonants and waxes inhibit or prevent this cracking. Various rubbers and rubber formulations containing such additives are customarily evaluated under static or dynamic tensile strain in laboratory ozone chambers. This standard provides for an accurate assessment of the ozone content of such chambers used in Test Methods D518, D1149, D1171, D3395 and ISO Standard8201;1431 I/II/III. For additional information on ozone analysis, refer to Code of Federal Regulations; Title 40 Parts 1 to 51. 1.1x00a0;These test methods cover the following three types of methods for the determination of ozone content in laboratory test chambers. Method A (UV absorption) is specified for reference or referee purposes and as a means of calibration for the alternative methods; Method B, instrumental device (electrochemical or chemiluminescence); and Method C, wet chemical techniques (see Appendix X1). These methods are primarily intended for use with tests for determining rubber ozone cracking resistance and thus are applicable over the ozone level range from 25 to 200 mPa. Note 1:x00a0;Prior to 1978, ozone concentrations were expressed in ASTM D11 Standards in parts per hundred million (pphm) of air by volume.

ASTM D1709-2009 用钢锥自由下落法测试塑料薄膜抗冲击性的标准试验方法
简介:Test Methods A and B are used to establish the weight of the dart when 50 % of the specimens fail under the conditions specified. Data obtained by one test method cannot be compared directly with the other test method nor with those obtained from tests employing different conditions of missile velocity, impinging surface diameter, effective specimen diameter, and thickness. The values obtained by these test variables are highly dependent on the method of film fabrication. The results obtained by Test Methods A and B are greatly influenced by the quality of film under test. The confidence limits of data obtained by this procedure can, therefore, vary significantly, depending on the sample quality, uniformity of film gage, die marks, contaminants, etc. (see Section 15). Test Methods A and B have been found useful for specification purposes. Correlation between test results and field performance can usually be established. The impact resistance of plastic film, while partly dependent on thickness, has no simple correlation with sample thickness. Hence, impact values cannot be normalized over a range of thickness without producing misleading data as to the actual impact resistance of the material. Data from these test methods are comparable only for specimens that vary by no more than x00B1;25 % from the nominal or average thickness of the specimens tested. Several impact test methods are used for film. It is sometimes desirable to know the relationships among test results derived by different test methods. A study was conducted in which four films made from two resins (polypropylene and linear low-density polyethylene), with two film thicknesses for each resin, were impacted using Test Methods D 1709 (Method A), D 3420 (Procedures A and B), and D 4272. The test results are shown in the Appendix. Differences in results between Test Methods D 1709 and D 4272 may be expected since Test Methods D 1709 represents failure initiated energy, while Test Method D 4272 is initiation plus completion energy. Some films may show consistency when the initiation energy is the same as the total energy. This statement and the test data also appear in the significance sections and appendixes of Test Methods D 3420 and D 4272.1.1 These test methods cover the determination of the energy that causes plastic film to fail under specified conditions of impact of a free-falling dart. This energy is expressed in terms of the weight (mass) of the missile falling from a specified height which would result in 50 % failure of specimens tested. 1.2 Two test methods are described: 1.2.1 Test Method A employs a dart with a 38.10 x00B1; 0.13-mm (1.500 x00B1; 0.005-in.) diameter hemispherical head dropped from a height of 0.66 x00B1; 0.01 m (26.0 x00B1; 0.4 in.). This test method may be used for films whose impact resistances require masses of about 50 g or less to about 2 kg to fracture them. 1.2.2 Test Method B employs a dart with a 50.80 x00B1; 0.13-mm (2.000 x00B1; 0.005-in.) diameter hemispherical head dropped from a height of 1.50 x00B1; 0.03 m (60.0 + 0.25, x2212;1.70 in.). Its range of applicability is from about 0.3 kg to about 2 kg. 1.3 Two testing techniques are described: 1.3.1 The standard technique is the staircase method. By this technique, a uniform missile weight increment is employed during te......

ASTM D4595-2009 用宽带法测试土工合成织物拉伸特性的标准试验方法
简介:The determination of the wide-width strip force x2212; elongation properties of geotextiles provides design parameters for reinforcement type applications, for example design of reinforced embankments over soft subgrades, reinforced soil retaining walls, and reinforcement of slopes. When strength is not necessarily a design consideration, an alternative test method may be used for acceptance testing. Test Method D 4595 for the determination of the wide-width strip tensile properties of geotextiles may be used for the acceptance testing of commercial shipments of geotextiles but caution is advised since information about between-laboratory precision is incomplete (Note 7). Comparative tests as directed in 5.1.1 may be advisable. In cases of a dispute arising from differences in reported test results when using Test Method D 4595 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student''s t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing began. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias. Most geotextiles can be tested by this test method. Some modification of clamping techniques may be necessary for a given geotextile depending upon its structure. Special clamping adaptions may be necessary with strong geotextiles or geotextiles made from glass fibers to prevent them from slipping in the clamps or being damaged as a result of being gripped in the clamps. Specimen clamping may be modified as required at the discretion of the individual laboratory providing a representative tensile strength is obtained. In any event, the procedure described in Section 10 of this test method for obtaining wide-width strip tensile strength must be maintained. This test method is applicable for testing geotextiles either dry or wet. It is used with a constant rate of extension type tension apparatus. The use of tensile strength test methods that restrict the clamped width dimension to 50 mm (2 in.) or less, such as the ravel, cut strip, and grab test procedures, have been found less suitable than this test method for determining design strength parameters for some geotextiles. This is particularly the case for nonwoven geotextiles. The wide-width strip technique has been explored by the industry and is recommended in these cases for geotextile applications. This test method may not be suited for some woven fabrics used in geotextile applications that exhibit strengths approximately 100 kN/m or 600 lbf/in. due to clamping and equipment limitations. In those cases, 100-mm (4-in.) width specimens may be substituted for 200-mm (8-in.) width specimens. On those fabrics, the contraction effect cited in 1.4 is minimal and, consequently, the standard comparison can continue to be made.1.1 This test method covers the measurement of tensile properties of geotextiles using a wide-width strip specimen tensile method. This test method is applicable to most geotextiles that include woven fabrics, nonwoven fabrics, layered fabrics, knit fabrics, and felts that are used for geotextile application. 1.2 This test method covers the measurement of tensile strength and......
