ASTM C1039-85(2005)

1.1 These test methods cover the determination of apparent porosity, apparent specific gravity, and bulk density of cores taken from graphite electrodes manufactured for use in electric arc furnaces. (See also C 559 and C 838.)

1.2 This standard does not purport to address 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.

The results of these test methods can be used as a quality control or quality assurance check of electrodes either during their manufacture or at the user’location. The results of these methods tend to be operator-sensitive, therefore, care must be taken in the execution of the test in order to obtain reproducible results.
