1.1本试验方法包括测定催化剂和催化剂载体的耐磨性和耐磨性。适用于片剂、挤出物、球体和大于约 1. / 16 在里面（1.6 mm）和小于约 3. / 4. 在里面（19毫米）。用于开发该方法的材料的磨损损失小于7%；然而，该方法应适用于具有更高磨损的材料。 1.2以英寸表示的数值- 磅单位应视为标准单位。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。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法被视为衡量催化剂在运输、搬运和使用过程中产生粉末的倾向性。然而，没有绝对的可接受性水平。获得的值主要与具有可比尺寸的其他材料（或相同材料的其他样品）的值有关。

1.1 This test method covers the determination of the attrition and abrasion resistance of catalysts and catalyst carriers. It is applicable to tablets, extrudate, spheres, and irregularly shaped particles larger than about 1 / 16 in. (1.6 mm) and smaller than about 3 / 4 in. (19 mm). The materials used in developing the method exhibited losses on attrition less than 7 %; however, the method should be applicable to materials giving much higher attritions. 1.2 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. 1.3 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. ====== Significance And Use ====== This test method is considered to be a measure of the propensity of a catalyst to produce fines in the course of transportation, handling, and use. However, there is no absolute level of acceptability. The values obtained are significant principally in relation to values for other materials (or other samples of the same material) of comparable size.
