Historical (view previous versions of standard)
This practice establishes the standard procedures for the determination of the Scleroscope hardness of metallic materials, the verification of Scleroscope hardness instruments by a standardized test block method, and alternatively, the calibration of standardized hardness test blocks used for the verification of Scleroscope hardness instruments.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This practice covers the determination of the Scleroscope hardness of metallic materials (Part A), the verification of Scleroscope hardness instruments (Part B), and the calibration of standardized hardness test blocks (Part C).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
