ASTM D4781 – Standard Test Method for Mechanically Tapped Packing Density of Fine Catalyst Particles and Catalyst Carrier Particles
Description:
Significance and Use
5.1 This test method is for measuring the mechanically tapped packing density of powders that are smaller than 0.8 mm in diameter, such as Fluidized Catalytic Cracking (FCC) Catalysts .
Scope
1.1 This test method covers the determination of the mechanically tapped packing density of fine catalyst and catalyst carrier particles smaller than 0.8 mm in diameter.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
