简介:1.1x00a0;The practice describes the procedures for the rehabilitation of gravity pipes, culverts, tunnels, and conduits by the installation of a field-fabricated PVC liner system. After installation of the liner system, cementitious grout is pumped into the annular space between the liner and the host structure. The rehabilitation of the host structure by this installation practice results in a rigid composite structure (PVC liner/grout/existing pipe). This type of rehabilitation process is suitable for a variety of gravity pipe applications such as storm sewers, sanitary sewers, and culverts; and with geometries including circular, egg, ovoid, elliptical, arch, and site-specific composite shapes. 1.2x00a0;The values stated in inch-pound units are to be regarded as standard.

简介:5.1x00a0;This test method is useful because the choice of a solvent system for removing water-formed deposits depends upon the ability of the dynamic solvent system to dissolve both unattached and attached deposits. 1.1x00a0;This test method covers the determination of the relative efficacy of dynamic solvent systems for dissolving water-formed deposits that have been removed from the underlying material or deposits attached to the underlying material. 1.2x00a0;The nature of this test method is such that statements of precision and bias as determined by round robin tests could mislead users of this test method (see Sections 11 and 12). Therefore, no precision and bias statements are made. 1.3x00a0;The values stated in SI units are to be regarded as standard.

ASTM D7928-2016 采用沉淀 (比重计) 分析测定细粒土粒径分布 (级配) 的标准试验方法
简介:5.1x00a0;Particle-size distribution (gradation) is a descriptive term referring to the proportions by dry mass of a soil distributed over specified particle-size ranges. The gradation curve generated using this method yields the amount of silt and clay size fractions present in the soil based on size definitions, not mineralogy or Atterberg limit data. 5.2x00a0;Determination of the clay size fraction, which is material finer than 2 x00b5;m, is used in combination with the Plasticity Index (Test Methods D4318) to compute the activity, which provides an indication of the mineralogy of the clay fraction. 5.3x00a0;The gradation of the silt and clay size fractions is an important factor in determining the susceptibility of fine-grained soils to frost action. 5.4x00a0;The gradation of a soil is an indicator of engineering properties. Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil. However, engineering behavior is dependent upon many factors, such as effective stress, mineral type, structure, plasticity, and geological origin, and cannot be based solely upon gradation. 5.5x00a0;Some types of soil require special treatment in order to correctly determine the particle sizes. For example, chemical cementing agents can bond clay particles together and should be treated in an effort to remove the cementing agents when possible. Hydrogen peroxide and moderate heat can digest organics. Hydrochloric acid can remove carbonates by washing and Dithionite-Citrate-Bicarbonate extraction can be used to remove iron oxides. Leaching with test water can be used to reduce salt concentration. All of these treatments, however, add significant time and effort when performing the sedimentation test and are allowable but outside the scope of this test method. 5.6x00a0;The size limits of the sedimentation test are from about 100 x00b5;m to about 1 x00b5;m. The length of time required to obtain a stable initial reading on the hydrometer controls the upper range of results, and the test duration controls the lower range. 5.7x00a0;The shape and density of the grains are important to the results. Stokesx2019; Law is assumed to be valid for spherical particles even though fine silt- and clay-sized particles are more likely to be plate-shaped and have greater mineral densities than larger particles. Note 5: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/sampling/inspection/etc. Users of this standard 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. 1.1

简介:The CTAB molecule is relatively large; so it is not adsorbed in micropores or on surface roughness. Thus, the CTAB surface area reflects only the surface of the silica that is available for interaction with rubber molecules.1.1 This test method covers the measurement of the specific surface area of precipitated silicas exclusive of area contained in micropores too small to admit hexadecyltrimethylammonium bromide (cetyltrimethylammonium bromide, commonly referred to as CTAB) molecules. This test method is suitable for characterizing rubber-grade silicas of all types. 1.2 The values stated in SI units are to be regarded as the standard. The values given 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 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:1.1 This specification covers iron-chromium-nickel-copper corrosion-resistant steel castings, capable of being strengthened by precipitation hardening heat treatment. 1.2 These castings may be used in services requiring corrosion resistance and high strengths at temperatures up to 600x00B0;F [315x00B0;C]. They may be machined in the solution-annealed condition and subsequently precipitation hardened to the desired high-strength mechanical properties specified in Table S14.1 with little danger of cracking or distortion. 1.3 The material is not intended for use in the solution-annealed condition. Note 18212;If the service environment in which the material is to be used is considered conducive to stress-corrosion cracking, precipitation hardening should be performed at a temperature that will minimize the susceptibility of the material to this type of attack. 1.4 Supplementary requirements of an optional nature are provided for use at the option of the purchaser. The Supplementary requirements shall apply only when specified individually by the purchaser in the purchase order or contract. 1.5 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. 1.6 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. 1.6.1 Within the text, the SI units are shown in brackets.

ASTM D6800-2012 微量金属的电感耦合等离子体质谱(ICP-MS)分析法使用还原沉淀预浓缩技术对水样制备的标准操作规程
简介:Ambient marine waters generally contain very low concentrations of toxic metals that require sensitive analytical methods, such as ICP-MS, to detect and measure the metalx0027;s concentrations. Due to the high dissolved salt concentrations present in seawater, sample pretreatment is required to remove signal suppression and significant polyatomic interferences due to the matrix both of which compromise detection limits.1.1 Toxic elements may be present in ambient waters and may enter the food chain via uptake by plants and animals; the actual concentrations of toxic metals are usually sub-ng/mL. The U.S. EPA has published its Water Quality Standards in the U.S. Federal Register 40 CFR 131.36, Minimum requirements for water quality standards submission, Ch. I (7-1-00 Edition), see Annex, Table A1.1. The U.S. EPA has also developed Method 1640 to meet these requirements, see Annex, Table A1.2. 1.2 Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) is a technique with sufficient sensitivity to routinely measure toxic elements in ambient waters, both fresh and saline (Test Method D5673). However saline and hard water matrices pose analytical challenges for direct multielement analysis by ICP-MS at the required sub-ng/mL levels. 1.3 This standard practice describes a method used to prepare water samples for subsequent multielement analysis using ICP-MS. The practice is applicable to seawater and fresh water matrices, which may be filtered or digested. Samples prepared by this method have been analyzed by ICP-MS for the elements listed in Annex, Table A1.3). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.
