TECHNICAL ISSUES RELATED TO ISO HARDNESS TEST STANDARDS

Takashi Yamamoto, Masayuki Yamamoto

Abstract

The ISO standards for hardness tests, including Rockwell, Vickers and Brinell, have become bloated, compelling users of the standards to pay an excessive amount of attention and cost to comply with them. In essence, good standards should be simple and clear. Experts on hardness tests and creators of standards should give more consideration when making such standards. <BR />From this standpoint, as a manufacturer specializing in the production of hardness test blocks, we present some issues to be improved concerning relatively recent hardness test standards based on theoretical considerations and experimental facts.
