ASTM B379-99

Standard Specification for Phosphorized Coppers-Refinery Shapes

SCOPE
1.1 This specification establishes the requirements for phosphorized copper wire bars, billets, and cakes.  Note 1-Wire bars furnished under this specification do not conform in dimensions with that furnished under Specification B5.
1.2 The values in inch-pound units are the standard. SI values given in parentheses are for information only.  
1.3 The following hazard caveat applies to Sections 14.2 and 14.3 of this specification: 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
