Organization: ASTM International
Publication Date: 1 January 2000
Status: inactive
Page Count: 6
ICS Code (Powder metallurgy): 77.160
scope:

1.1 This test method specifies procedures for the metallographic determination of apparent porosity in cemented carbides.

Note 1--The term "apparent porosity" is construed to mean all microstructures observed on a properly prepared, unetched surface, including structures resulting from uncombined carbon, non-metallic inclusions, etc., as well as true, inherent porosity.

1.2 This standard does not purport to address all of the safety problems, 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.
