scope:
This Standard specifies the calibration method of the hardness reference blocks (hereafter referred to as "reference blocks") to be used for the indirect verification and the daily accuracy control of the testing machine for the Vickers hardness test specified in JIS B 7725. Whereas the International Standard limits the scope to indentations with diagonals 20 μm or over, this Standard does not specify the minimum value for the length of diagonals.
NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:
ISO 6507-3 : 2005 Metallic materials - Vickers hardness test - Part 3: Calibration ofreference blocks (MOD)
The 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/lEC Guide 21-1.
