Standard Test Method for Single Pellet Crush Strength of Formed Catalyst Shapes 成型催化剂形状的单颗粒压碎强度的标准试验方法
发布日期: 2006-04-01
1.1本试验方法包括测定成型催化剂的抗压性,适用于规则形状的催化剂,如片剂和球体。挤出物、颗粒状材料和其他不规则形状除外。 1.2本试验方法确定了0至50 lbf(0至220 N)范围内的平均抗压强度。 1.3以英寸-磅UNT表示的值应视为标准值。括号中给出的值是到SI UNT的数学转换,仅供参考,不被视为标准值。 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====== 本试验方法旨在提供有关催化剂形状在使用过程中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 to compressive force and is applicable to regular catalyst shapes such as tablets and spheres. 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). 1.3 The values stated in inch-pound unts are to be regarded as standard. The values given in parentheses are mathematical conversions to SI unts that are provided for information only and are not considered standard. 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 intended to provide information concerning the ability of a catalyst shape to retain physical integrity during use.
