Historical Standard: ASTM B276-91(2000) Standard Test Method for Apparent Porosity in Cemented Carbides
SUPERSEDED (see Active link, below)
ASTM B276
1. 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
