1.1 This test method covers a procedure for determination of the effective case depth of powder metallurgy (P/M) parts.
1.2 A microindentation hardness traverse procedure is described to determine effective case depth. This test method may be used to determine the effective case depth for all types of hardened cases.
1.3 The procedure for determining the microindentation hardness of powder metallurgy materials, as described in Test Method B 933 shall be followed.
1.4 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.
