Significance and Use
5.1 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.
5.2 This test method is suitable for specification acceptance, manufacturing control, and research and development purposes.
1.1 This test method covers the determination of the relative attrition characteristics of FCC catalysts by means of air jet attrition. Other fine powder catalysts can be analyzed by this test method but the precision of this test method has been determined only for FCC catalysts. It is applicable to spherically or irregularly shaped particles which range in size between 10 and 180 μm, have skeletal densities between 2.4 and 3.0 g/cm3 (2400 and 3000 kg/m3) (see ) and are insoluble in water. Particles less than 20 μm are considered fines.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
