Standard Test Method for Single Pellet Crush Strength of Formed Catalyst Shapes
|Publication Date:||1 April 2006|
|ICS Code (Chemical reagents):||71.040.30|
significance And Use:
This test method is intended to provide information concerning the ability of a catalyst shape to retain physical integrity during use.
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.
