Abstract

This test method specifies the determination of the microhardness of metallic coatings upon various substrates (electroplated coatings). Measurements shall be made with the Knoop indenter under specified test loads, and the hardness shall be reported as a Knoop hardness number (HK).

Scope

1.1 This test method covers the determination of the hardness of metallic coatings upon various substrates. The measurements are made with the Knoop indenter under a test load of 0.245 N (25 gf) or 0.981 N (100 gf).

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