1.1 This test method covers the dry sieve analysis of metal powders, using sieves with openings ranging from 45 to 850 micrometres.
1.2 This test method is based on a particular type of mechanical sieve shaker (see ). Other types of sieve shakers are also available, but their precision and reproducibility have not been determined.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
Significance and Use
4.1 The particle size distribution of a metal powder affects its behavior in P/M processing and other applications of these materials. The test method may be part of the purchase agreement between powder supplier and user, or it may be an internal quality control test for either.
