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 units are to be regarded as the standard. The values in parentheses for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
