BS EN ISO 6507-1:2018

This standard BS EN ISO 6507-1:2018 Metallic materials. Vickers hardness test is classified in these ICS categories:

• 77.040.10 Mechanical testing of metals

This document specifies the Vickers hardness test method for the three different ranges of test force for metallic materials including hardmetals and other cemented carbides (see Table 1).

Table 1

Ranges of test force

Ranges of test force, F N	Hardness symbol	Designation
F ≥ 49,03	≥HV 5	Vickers hardness test
1,961 ≤ F < 49,03	HV 0,2 to	Low-force Vickers hardness test
0,009 807 ≤ F < 1,961	HV 0,001 to	Vickers microhardness test

The Vickers hardness test is specified in this document for lengths of indentation diagonals between 0,020 mm and 1,400 mm. Using this method to determine Vickers hardness from smaller indentations is outside the scope of this document as results would suffer from large uncertainties due to the limitations of optical measurement and imperfections in tip geometry.

A periodic verification method is specified for routine checking of the testing machine in service by the user.

For specific materials and/or products, particular International Standards exist.
