Organization: ASTM
Publication Date: 15 August 1995
Status: inactive
Page Count: 2
ICS Code (Other non-ferrous metals and their alloys): 77.120.99
scope:

This test method covers the determination of the hardness of metallic materials used for electrical contacts. Rockwell, Rockwell superficial, Brinell, and microhardness tests are included, along with information on the limitations and use of these tests.

The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use.
