ASTM B214 – Standard Test Method for Sieve Analysis of Metal Powders
Significance and Use
4.1 The particle size distribution of a metal powder affects its behavior in PM 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.
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 5.2). Other types of sieve shakers are also available, but their precision and reproducibility have not been determined.
1.3 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
