This Standard specifies a method for the calibration of hardness reference blocks (hereafter referred to as reference blocks) to be used for the indirect verification and daily accuracy control of Vickers hardness testing machines as specified in JIS B 7725 (hereafter referred to as the testing machine).

It should be noted that Vickers hardness determination from indentations < 20 µm in diagonal length may cause large uncertainties in the results.

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

ISO 6507-3 : 2018 Metallic materials — Vickers hardness test — Part 3 : Calibration of reference blocks (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.
