1.1 这些测试方法旨在评估树脂、二氧化硅、硅酸盐、硫和液压材料、灌浆、整体表面和聚合物混凝土在预期使用条件下的耐化学性。这些试验方法用于测定试样暴露于介质后，试样和试验介质的以下特性的变化: 1.1.1 试样重量， 1.1.2 试样外观， 1.1.3 测试介质的外观，以及 1.1.4 试样的抗压强度。 1.2 试验方法A概述了通常用于骨料小于0.0625英寸的系统的试验程序。（1.6毫米）。试验方法B涵盖了通常用于含有0.0625至0.4in骨料的系统的试验程序。（1.6至1.0 mm）。试验方法C用于含有大于0的骨料的系统。 4英寸。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 通过这些试验方法获得的结果应作为选择特定应用的耐化学性材料的指南，而不是唯一依据。未试图将可能影响材料在实际使用时性能的所有各种因素纳入这些试验方法中。通过这些试验方法获得的强度值不应用于评估耐化学品材料的抗压强度。应使用特定材料的适当ASTM试验方法来确定和评估抗压强度。

1.1 These test methods are intended to evaluate the chemical resistance of resin, silica, silicate, sulfur, and hydraulic materials, grouts, monolithic surfacings, and polymer concretes under anticipated service conditions. These test methods provide for the determination of changes in the following properties of the test specimens and test medium after exposure of the specimens to the medium: 1.1.1 Weight of specimen, 1.1.2 Appearance of specimen, 1.1.3 Appearance of test medium, and 1.1.4 Compressive strength of specimens. 1.2 Test Method A outlines the testing procedure generally used for systems containing aggregate less than 0.0625 in. (1.6 mm) in size. Test Method B covers the testing procedure generally used for systems containing aggregate from 0.0625 to 0.4 in. (1.6 to 1.0 mm) in size. Test Method C is used for systems containing aggregate larger than 0.4 in. 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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The results obtained by these test methods should serve as a guide in, but not as the sole basis for, selection of a chemical-resistant material for a particular application. No attempt has been made to incorporate into these test methods all the various factors that may affect the performance of a material when subjected to actual service. The strength values obtained by these test methods should not be used to evaluate the compressive strength of chemical-resistant materials. The appropriate ASTM test method for the specific material should be used for determining and evaluating the compressive strength.
