1.1 This standard covers a test method that may be used to measure the sum of the changes in dimensions that occur when a metal powder is first compacted into a test specimen and then sintered.
1.2 The dimensional change is determined by a quantitative laboratory procedure in which the arithmetic difference between the dimensions of a die cavity and the dimensions of a sintered test specimen produced from that die is calculated and expressed as a percent growth or shrinkage.
1.3 With the exception of density values, for which the g/cm3 unit is the industry standard, the values stated in inch-pound units are to be regarded as the standard. The SI equivalents shown in parentheses, have been converted in accordance with IEEE/ASTM Standard SI 10, may be approximate, and are only for information.
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.
