1.1 本试验方法包括测定成型催化剂和催化剂载体对压缩力的耐受性，适用于常规催化剂形状，如片剂和球体。其他形成的催化剂和催化剂载体挤出物、颗粒材料和其他不规则形状被特别排除。 1.2 本试验方法确定了0至50磅力（0至220 N）范围内的平均抗压强度。一些材料的抗压强度可能高于50磅力（220N）；试验方法适用于这些材料，但试验精度尚不清楚。 1.3 单位- 以英寸-磅单位表示的数值应视为标准值。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 本标准并不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建立适当的安全、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====== 5.1 本试验方法旨在提供有关催化剂形状在使用期间保持物理完整性的能力的信息。

1.1 This test method covers determining the resistance of formed catalysts and catalyst carriers to compressive force and is applicable to regular catalyst shapes such as tablets and spheres. Other formed catalysts and catalyst carriers extrudates, granular materials, and other irregular shapes are specifically excluded. 1.2 This test method determines the average crush strength in the range from 0 to 50 lbf (0 to 220 N). Some materials may have crush strengths above 50 lbf (220N); the test method is applicable to these materials, but the precision of the test is not known. 1.3 Units— 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 ====== 5.1 This test method is intended to provide information concerning the ability of a catalyst shape to retain physical integrity during use.
