scope:

This Standard 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).

The Vickers hardness test specified in this Standard is for lengths of indentation diagonals between 0.020 mm and 1.400 mm; it may be used for lengths of indentation diagonals < 0.020 mm and/or test force of < 0.009 807 N upon agreement between the parties involved.

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 standards exist.

NOTE 1 Using the method specified in this Standard for determination from indentations < 0.020 mm in diagonal length may cause large uncertainties in the results.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 6507-1:2018 Metallic materials-Vickers hardness test-Part 1: Test method (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.
