Rockwell hardness test-Test method
|Publication Date:||22 February 2016|
|ICS Code (Mechanical testing of metals):||77.040.10|
This Standard specifies the method for Rockwell regular and Rockwell superficial hardness tests for metallic materials and is applicable to stationary and portable hardness testing machines
For specific materials and/or products like hardmetals, other specific standards apply (for instance, ISO 3738-1 and ISO 4498).
NOTE 1 Attention is drawn to the fact that, in ISO 6508-1, the use of tungsten carbide composite for ball indenters (hereafter--refe-rre
NOTE 2 Attention is drawn to the fact that the result obtained with hardmetal ball may be significantly different from the result obtained with a steel balls
NOTE 3 (Editor's note: this note is unrelated to English translation therefore omitted.) NOTE 4 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 6508-1: 2015 Metallic materials-Rockwell 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.
WARNING Persons carrying out tests based on this Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety probleams, if any associated with its use.
