scope:
This Standard specifies methods of direct and indirect verification of testing machines used for determining Brinell hardness in accordance with JIS Z 2243.
This Standard is applicable to both fixed location and portable hardness testing machines (hereafter referred to as testing machines).
For machines that are incapable of satisfying the specified force-time profile, the direct verification of force and testing cycle can be modified by the use of Annex B.
NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 6506-2: 2014 Metallic materials-Brinell hardness test-Part 2: Verification and calibration of testing machines (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.
