Formerly under the jurisdiction of Committee E28 on Mechanical Testing, this practice was withdrawn in February 2006 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This practice lists the physical requirements that an impact machine shall meet in order to be registered as a reference machine.
1.2 This practice describes the procedure by which a reference machine shall be qualified to make tests to establish reference values.
1.3 These requirements and procedures are not intended to be applied to impact machines and testing procedures used for purposes other than to qualify machines for the determination of reference values of verification specimens.
1.4 This practice does not describe the procedure by which the reference value for a specified reference material is determined. The procedure varies with the material being tested and is to be found in different standards for various specified verification materials.
1.5 Values stated in inch-pound units are to be regarded as the standard. SI units are given for information only.
1.6 This standard does not purport to address all of the safety problems 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.
