ASTM D4512-03(2008)
(Test Method)Standard Test Method for Vibrated Apparent Packing Density of Fine Catalyst and Catalyst Carrier Particles and Powder
Standard Test Method for Vibrated Apparent Packing Density of Fine Catalyst and Catalyst Carrier Particles and Powder
SIGNIFICANCE AND USE
This test method is for measuring the apparent packing density of catalyst or catalyst carrier powders that are smaller than 0.8 mm in diameter.
SCOPE
1.1 This test method covers the determination of the apparent packing density of fine catalyst and catalyst carrier powders 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.
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.
