ASTM C1581/C1581M-2009a 测定限制收缩下的灰浆和混凝土断裂老化和诱导拉伸应力特性的标准试验方法
简介:This test method is for relative comparison of materials and is not intended to determine the age at cracking of mortar or concrete in any specific type of structure, configuration, or exposure. This test method is applicable to mixtures with aggregates of 13-mm [0.5-in.] maximum nominal size or less. This test method is useful for determining the relative likelihood of early-age cracking of different cementitious mixtures and for aiding in the selection of cement-based materials that are less likely to crack under retrained shrinkage. Actual cracking tendency in service depends on many variables including type of structure, degree of restraint, rate of property development, construction and curing methods, and environmental conditions. This test method can be used to determine the relative effects of material variations on induced tensile stresses and cracking potential. These variations can include, but are not limited to, aggregate source, aggregate gradation, cement type, cement content, water content, supplementary cementing materials, or chemical admixtures. For materials that have not cracked during the test, the rate of tensile stress development at the time the test is terminated provides a basis for comparison of the materials. 1.1 This test method covers the laboratory determination of the age at cracking and induced tensile stress characteristics of mortar or concrete specimens under restrained shrinkage. The procedure can be used to determine the effects of variations in the proportions and material properties of mortar or concrete on cracking due to both drying shrinkage and deformations caused by autogenous shrinkage and heat of hydration. 1.2 This test method is not intended for expansive materials. 1.3 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. 1.4 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 to determine the applicability of regulatory limitations prior to use. (Warningx2014;Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. )

ASTM D3826-1998(2008) 用拉伸试验对聚乙烯和聚丙烯老化过程的最终老化点的测定的标准实施规程
简介:The tensile elongation property determined by this practice is of value for the characterization of degradable materials. The tensile elongation property may vary with specimen thickness, method of preparation, speed of testing, type of grips used, and manner of measuring test extension. Consequently, where precise comparative results are desired, these factors must be carefully controlled. The tensile elongation property may be utilized to provide data for research and development and engineering design as well as quality control specifications. However, data from such tests cannot be considered significant for applications differing widely from the load-time scale of the test employed. Materials that fail by tearing give anomalous data that cannot be compared with those from normal failure. Before proceeding with this test method, reference should be made to the specifications of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters or a combination thereof, covered in the material specifications shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply. 1.1 This practice covers the determination of a degradation-end point (a brittle point) for degradable polyethylene/polypropylene films and sheeting less than 1.0 mm (0.04 in.) thick. This practice is not intended for determination of the rate of degree of degradation of a polyethylene/polypropylene film or sheet, but rather, to assess when in the course of its degradation under some condition, a brittle point is reached. If one wishes to monitor tensile elongation during the degradation process (such as when the tensile elongation is significantly greater than 5 %), Test Method D 882 is recommended. This practice should not be considered the only way of determining a degradation-end point. 1.2 Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined in accordance with Test Method D 638. 1.3 Use a static weighing-constant rate of grip separation test. This procedure employs a constant rate of separation of the grips holding the sample and a static load cell. Note 18212;This procedure is based on the use of grip separation as a measure of extension; however, the desirability of using extension indicators accurate to x00B1;1.0 % or better as specified in Test Method D 638 is recognized, and a provision for the use of such instrumentation is incorporated in the procedure. 1.4 This procedure has been successful for determining the degradation end point of ethylene-carbon-monoxide copolymers and has screened successfully two other additive-type polyethylenes in a round robin test. 1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 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. 1.7 There is no equivalent ISO standard.

简介:本标准规定了三种测量试样在给定伸长状态下应力变化的方法,目的是测定橡胶硫化胶的老化性能。方法A供在连续应变条件下的测量采用。方法B是在间歇应变条件下的测量的优先选择的方法。在方法A和B两种情况下,使用应力松弛仪记录在老化温度下的应力。方法C可以代替方法B用于在间歇应变条件下的测量。在方法C中,试样从老化环境中取出,在标准实验室温度下测量应力。在单一的老化高温下的测量,可用于质量控制的目的,如耐热老化的程度。根据GB/T 20028的描述的方法,在一系列温度下进行测量以预测长期的老化性能,可用于研究和开发的目的。在三个方法之间无法互相推算,所用的方法取决于试验目的。

ISO 6914-2008 硫化或热塑性橡胶.用拉伸中应力松弛测量法测定老化特性
简介:This International Standard describes three methods for the measurement of the change of stress in a testpiece at a given elongation for the purpose of determining the ageing characteristics of a rubber.- Method A is intended for measurement under continuous strain conditions. - Method B is the preferred method for measurement under intermittent strain conditions.In the case of both methods A and B, a stress relaxometer is used to record the stress at the temperature ofageing.-- Method C is an alternative to method B for measurement under intermittent strain conditions in which the test piece is removed from the ageing environment for measurement of the stress at standard laboratory temperature.The necessary calibration schedule for this type of measurement is given in Annex A.Measurements at a single elevated ageing temperature can be used for quality control purposes as a measureof heat-ageing resistance. Measurements at a number of temperatures can be used for research anddevelopment purposes to estimate long-term ageing characteristics in accordance with the proceduresdescribed in ISO 11346.No agreement between the three methods should be inferred. The method used will depend on the purpose ofthe test.

ASTM D3826-1998 用拉伸试验对聚乙烯和聚丙烯老化过程的最终老化点的测定
简介:1.1 This practice covers the determination of a degradation-end point ( a brittle point ) for degradable polyethylene/ polypropylene films and sheeting less than 1.0 mm (0.04 in.) thick. This practice is not intended for determination of the rate of degree of degradation of a polyethylene/ polypropylene film or sheet, but rather, to assess when in the course of its degradation under some condition, a brittle point is reached. If one wishes to monitor tensile elongation during the degradation process (such as when the tensile elongation is significantly greater than 5%), Test Method D882 is recommended. This practice should not be considered the only way of determining a degradation-end point. Other degradation-end-point procedures are currently being evaluated and developed by Subcommittee D20.96 for polyolefins and other plastics such as polystyrene. For example, Test Method D1922 is being considered as a test for determining a degradation-end point in polyethylene/ polypropylene films. Practice D1435 may be used for determining outdoor weathering of polyethylene/ polypropylene films and sheeting. 1.2 Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined in accordance with Test Method D638. 1.3 Use a static weighing-constant rate of grip separation test. This procedure employs a constant rate of separation of the grips holding the sample and a static load cell. Note 1-This procedure is based on the use of grip separation as a measure of extension; however, the desirability of using extension indicators accurate to +1.0% or better as specified in Test Method D638 is recognized, and a provision for the use of such instrumentation is incorporated in the procedure. 1.4 This procedure has been successful for determining the degradation end point of ethylene-carbon-monoxide copolymers, but its utility for other polymers is yet to be determined by round-robin testing. 1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.6 This standard does not purport to address all of the safety problems, if any, associated with its use.

ASTM C1581-2004 测定限制收缩下的灰浆和混凝土断裂老化和诱导拉伸应力特性的标准试验方法
简介:This test method is for relative comparison of materials and is not intended to determine the age at cracking of mortar or concrete in any specific type of structure, configuration, or exposure. This test method is applicable to mixtures with aggregates of 0.5-in. (13-mm) maximum nominal size or less. This test method is useful for determining the relative likelihood of early-age cracking of different cementitious mixtures and for aiding in the selection of cement-based materials that are less likely to crack under retrained shrinkage. Actual cracking tendency in service depends on many variables including type of structure, degree of restraint, rate of property development, construction and curing methods, and environmental conditions. This test method can be used to determine the relative effects of material variations on induced tensile stresses and cracking potential. These variations can include, but are not limited to, aggregate source, aggregate gradation, cement type, cement content, water content, supplementary cementing materials, or chemical admixtures. For materials that have not cracked during the test, the rate of tensile stress development at the time the test is terminated provides a basis for comparison of the materials. 1.1 This test method covers the laboratory determination of the age at cracking and induced tensile stress characteristics of mortar or concrete specimens under restrained shrinkage. The procedure can be used to determine the effects of variations in the proportions and material properties of mortar or concrete on cracking due to both drying shrinkage and deformations caused by autogenous shrinkage and heat of hydration.1.2 This test method is not intended for expansive materials.1.3 The values stated in inch-pound units are to be regarded as standard. The values shown in parenthesis are in SI units and are given for information only.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 to determine the applicability of regulatory limitations prior to use. (Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)

ASTM F2018-2000(2006) 使用平应力拉伸样品测定塑料老化时间的标准试验方法
简介:The data obtained by this test method are useful for establishing stress versus failure-time relationships in a controlled environment. The long-term strength (LTS) is determined primarily for materials used in molding applications. The LTS categorized in accordance with Table 1 of ASTM D 2837 is known as the SDB (strength design basis). Note 18212;These SDB values will be published in PPI TR-4 for materials used in molding applications only. The test method can also be used on an experimental basis for pipe-grade materials as an indicator of stress-rupture performance. The long-term strength or SDB values obtained by this test method are not intended to replace the HDB determined for pressure pipe tested in accordance with Test Method D 1598. In order to determine how plastics will perform in pipe fitting applications, it is necessary to establish the stress-failure time relationships over four or more decades of time (hours) in a controlled environment. Because of the nature of the test and specimens employed, no single line can adequately represent the data, and therefore the confidence limits should be established. Note 28212;Some materials may exhibit a nonlinear relationship between log-stress and log-failure time, usually at short failure-times. In such cases, the 105 - hour stress value computed on the basis of short-term test data may be significantly different than the value obtained when a distribution of data points in accordance with Test Method D 2837 is evaluated. However, these data may still be useful for quality control or other applications, provided correlation with long-term data has been established.1.1 This test method covers the requirements to determine the time-to-failure of thermoplastic resins for piping applications by uniaxial loading of a grooved tensile test specimen. This grooved tensile specimen achieves a multi-axial stress condition, which mimics the stress condition found in pressurized solid-wall plastic pipe. The ratio of the stress in the axial direction to the transverse direction approximates that for a pressurized solid-wall pipe specimen.1.2 It is intended that the data generated on these specimens be analyzed according to the methodology set forth in Test Method D 2837 to generate a long-term strength design value for the material.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.
