1.1 该试验方法包括测量基本砖和形状对水化的相对阻力。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值仅供参考。 1.3 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。 1.4 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====== 2.1 该试验方法比较了实验室试验中基本耐火砖和形状的相对抗水化性能。 2.2 这种测试方法可以估计相对水合潜力。 2.3 该测试方法在工业中使用，在某些情况下用于规范目的。 2.4 必须仔细使用这些结果作为预测基本砖或形状在实际储存或使用条件下是否会水合的手段。

1.1 This test method covers measurement of the relative resistance of basic brick and shapes to hydration. 1.2 The values stated in inch-pound 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 2.1 This test method compares relative resistance to hydration of basic refractory brick and shapes in laboratory tests. 2.2 This test method allows an estimate to be made of the relative potential for hydration. 2.3 The test method is used in industry and in some cases it is used for specification purposes. 2.4 The results must be carefully used as a means of predicting whether or not basic brick or shapes will hydrate under actual conditions of storage or service.
