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.
