ASTM B611-85(2000)e1

Standard Test Method for Abrasive Wear Resistance of Cemented Carbides

SCOPE
1.1 This test method covers the determination of abrasive wear resistance of cemented carbides.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents of inch-pound units are in parentheses and may be approximate.  
1.3 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.
