Mechanical Testing Committee Revises Brinell, Rockwell Hardness Test Methods

摘要

ASTM INTERNATIONAL STANDARDS E 10, Test Method for Brinell Hardness of Metallic Materials, and E 18, Test Methods for Rockwell Hardness and Rockwell Superficial Hardness of Metallic Materials, have both recently undergone extensive revisions. Both standards are under the jurisdiction of Subcommittee E28.06 on Indentation Hardness Testing, which is part of ASTM International Committee E28 on Mechanical Testing. "The intention of these revisions was to improve the standards by specifying requirements for traceability, clarifying requirements and procedures, revising procedures to reflect current practice, and adding requirements and procedures to make them better test methods," says Samuel Low, chair of Subcommittee E28.06. Low also says that it is important to note that there is no intention of removing from service any Rockwell or Brinell hardness testing machines that currently meet all of the requirements of ASTM E 10 or E 18.
