ASTM D4512-22

Standard Test Method for Vibrated Apparent Packing Density of Fine Catalyst and Catalyst Carrier Particles and Powder

SIGNIFICANCE AND USE
4.1 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 Units—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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

7.1 Heat an adequate amount of sample(s) at 400 6 15°C15 °C for not less than 3 h. Normally, this treatment can take place in
air; however, in the case of materials that might react with air at elevated temperatures (such as, prereduced catalysts) the heat
treatment shall take place in an inert atmosphere. After heating, cool the test sample(s) in a desiccator or other suitable container
to eliminate the possibility of moisture adsorption prior to testing.
