1.1 本试验方法包括耐化学性砂浆、灌浆、整体表面处理和聚合物混凝土的吸收测定。这些材料可以基于树脂、硅酸盐、二氧化硅或硫粘合剂。 1.2 模具方法A用于含有尺寸小于0.0625英寸（1.6毫米）的骨料的系统。模具方法B用于含有0.0625以下骨料的系统 英寸至0.4英寸（1.6 毫米至10毫米）。模具方法C用于含有大于0.4英寸骨料的系统。 1.3 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 通过该试验方法获得的结果应作为选择化学品的指南，但不是唯一的依据- 用于特定应用的耐腐蚀材料。没有试图在试验方法中纳入实际使用时可能影响材料性能的所有各种因素。 4.2 这不是渗透性测试，测试结果不得解释为测试材料渗透性的测量或指示。

1.1 This test method covers the determination of the absorption of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes. These materials may be based on resin, silicate, silica, or sulfur binders. 1.2 Mold Method A is used for systems containing aggregates less than 0.0625 in. (1.6 mm) in size. Mold Method B is used for systems containing aggregates from 0.0625 in. to 0.4 in. (1.6 mm to 10 mm) in size. Mold Method C is used for systems containing aggregates 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 this test method 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 in the test method all the various factors which may affect the performance of a material when subjected to actual service. 4.2 This is not a test for permeability and the test results are not to be interpreted as a measurement of, or indication of, the permeability properties of the materials tested.
