TEST METHODS USED TO CHARACTERIZE the properties of petroleum coke, pitch, carbon artifacts (anodes and cathodes), and manufactured carbon products and graphite are presented in this chapter. This includes the raw materials and artifacts used in the electrolytic production of aluminum as well as graphite and its artifacts. The information presented here was extracted from ASTM standards and from Refs 1 through 4. ASTM Subcommittee D02.05 on Properties of Fuels, Petroleum Coke and Carbon Material has developed the test methods for coke, pitch, and for electrode carbon products. Subcommittee D02.F0 on Manufactured Carbon and Graphite has developed the test methods for manufactured carbon and graphite. This subcommittee was originally ASTM Committee COS on Manufactured Carbon and Graphite, and it has recently been assimilated into ASTM Committee D02 on Petroleum and Lubricants as Subcommittee D02.F0.
