scope:

This Standard specifies a method for calibration of reference blocks of scales A to H, K, N, and T, to be used for the indirect verification and daily checks and maintenance of Rockwell hardness testing machines specified in JIS B 7726 (hereafter referred to as reference blocks).

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

ISO 6508-3 : 2015 Metallic materials - Rockwell hardness test - Part 3 : Calibra tion 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.
