This practice covers the allowable range of mechanical properties at each of three different energy levels of verification specimens of heat-treated steel.
Formerly under the jurisdiction of Committee E28 on Mechanical Testing, this practice was withdrawn in July 2004. This practice was withdrawn in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the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 covers the allowable range of mechanical properties at each of three different energy levels of verification specimens of heat-treated steel.
1.2 This practice does not specify the composition or heat treatment for these verification specimens, but Appendix X1 gives examples of composition and heat treatments that have been used successfully in the past.
1.3 This practice describes the procedure that shall be used to establish the value of impact energy that is furnished with the specimens.
1.4 This practice lists information which the supplier of verification specimens shall make available to the purchaser.
1.5 Values stated in inch-pound units are to be regarded as the standard. SI units are provided for information only.
1.6 This standard does not purport to address all of the safety concerns, 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.
