ASTM E1833-96

Standard Practice for Sampling of Blister Copper in Cast Form for Determination of Chemical Composition

SCOPE
1.1 This practice describes a procedure for the sampling and sample preparation of cast blister copper for the determination of chemical composition.  
1.2 This practice is intended to cover the general principles of sampling applicable to cast blister copper forms.  
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.
