ASTM B250M-95

Standard Specification for General Requirements for Wrought Copper Alloy Wire [Metric] (Withdrawn 2001)

SCOPE
1.1 This specification establishes a group of requirements common to wrought copper alloy wire and shall apply to Specifications B16M, B99M, B159M, B197M, and B206M to the extent referenced therein.
