Testing of metallic materials; Vickers hardness test, HV 0,2 to HV 100

This technical specification outlines procedures for conducting Vickers hardness tests on metallic materials within a load range corresponding to scales from HV0.2 to HV100. The document details the methodology required to ensure accurate and reproducible measurements of material hardness properties. It specifies the necessary equipment calibration, the preparation of test specimens, and the application of the indenter under defined loads. The text provides guidance on measuring the diagonal of the indentation and calculating the resulting hardness value. By adhering to these defined protocols, manufacturers and laboratories can evaluate the hardness characteristics of various metal alloys consistently. The guidelines cover aspects related to test piece preparation, the selection of appropriate test loads, and the interpretation of results to verify material quality and mechanical performance against established criteria. This framework supports quality control processes in metallurgical industries by establishing a uniform approach to hardness assessment.
