Standard Test Method for Radial Crush Strength of Extruded Catalyst and Catalyst Carrier Particles

1.1 This test method covers and is suitable for determining the resistance of extruded catalysts and catalyst carriers to compressive force from the side.

1.2 This test method was developed using extruded catalyst and catalyst carriers from 1/16to 1/8 in. in diameter (0.159 to 0.318 cm) and limited to pieces with a length to diameter ratio greater than or equal to 1:1. This test method may be applicable to other diameters.

1.3 This test method is suitable for the determination of mean crush strength per millimetre in the range of 0 to 15 lbf/mm (0 to 65 N/mm).

1.4 The values stated in pounds lbf/mm units are to be regarded as the standard. The values given in parentheses are provided for information only.

1.5 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 to determine the applicability of regulatory limitations before use.
