The ASTM B578-21 standard specifies a test method for the determination of microhardness of Eletroplating coatings. Hardness measurement of metallic coatings under a specific load (0.245N or 0.981N) is performed using a Knoop indenter in the test. The results are reported as Knoop Hardness Value (HK). The standard applies to metallic coatings on a variety of substrates, ensuring conformity and Reliability of measurements. Users should establish appropriate safety and health practices and follow relevant regulations when using this standard.
