    Significance and Use

    This test method is intended to provide information concerning the ability of a powdered catalyst to resist particle size reduction during use in a fluidized environment.

    This test method is suitable for specification acceptance, manufacturing control, and research and development purposes.

    1. Scope

    1.1 This test method covers the determination of the relative attrition characteristics of powdered catalysts by means of air jet attrition. It is applicable to spherically or irregularly shaped particles which range in size between 10 and 180 m, have skeletal densities between 2.4 and 3.0 g/cm3 (2400 and 3000 kg/m3) (see IEEE/ASTM SI-10) and are insoluble in water. Particles less than 20 m are considered fines.

    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.
