1. Scope
1.1 This test method primarily covers a procedure for determining the change in dimensions that occurs as a result of pressing and sintering a metal powder specimen. The size change referred to is the difference between the die size and the size of the sintered specimen after it has cooled to room temperature, expressed as a percentage. This size change is a basic characteristic of the metal powder.
1.2 The general procedure of measuring a test specimen and die, then calculating the dimensional change, as described in this test method, also may be used to determine green expansion, heat treat changes or other dimensional changes of test specimens that result from processing steps.
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents are in parentheses and may be approximate.
1.4 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.
