Scope
1.1 This test method covers Rockwell L scale hardness testing of fine-grained graphite materials with grain size less than 0.8 m ( 1/32 in.) and a hardness range between 0 and 120.
1.2 Test Methods E18 shall be followed except where otherwise indicated.
1.3 The values stated in acceptable metric units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.4 This standard does not purport to address all of the safety problems, 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.
