RECENT CHANGES AND ADDITIONS TO THE HARDNESS TEST METHODS DEVELOPED AND PUBLISHED BY ASTM-INTERNATIONAL

Samuel Low, Rodney Jiggetts

Abstract

Since the mid 1990s, several factors have influenced the standards development organization ASTMInternational to make changes and additions to their published hardness test method standards. These factors included the advent of laboratory quality systems and the resulting need for uncertainty analysis; technological advances in testing equipment and measurement methods; and the recognition that improvement to the methods could be made. The result has been to improve the existing standards and develop new standards to meet evolving needs of industrial users. Some of the more important changes and additions to the ASTM-International hardness standards are discussed.
