ASTM D2638 – Standard Test Method for Real Density of Calcined Petroleum Coke by Helium Pycnometer
Description:
Significance and Use
5.1 The real density of calcined petroleum coke directly influences the physical and chemical properties of the manufactured carbon and graphite artifacts for which it is used. Density, therefore, is a major quality specification of calcined petroleum coke and is used as a control in coke calcination.
Scope
1.1 This test method covers the determination of the real density (RD) of calcined petroleum coke. Real density, by definition is obtained when the particle size of the specimen is smaller than 75 µm (U.S. No. 200 Sieve).
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
