ASTM B188-02

Standard Specification for Seamless Copper Bus Pipe and Tube

ABSTRACT
This specification covers seamless copper bus pipe and tube intended for use as electrical conductors. The material shall be manufactured by such hot-working, cold-working, and annealing processing as to produce a uniform, seamless wrought structure in the finished product. The method of manufacture shall be such that the finished material conforms to the specified temper properties. The material shall conform to the requirements for the copper UNS no. as specified. The material shall be furnished in either the O60 (soft anneal) or H80 (hard drawn) temper. The material shall conform to the maximum electrical resistivity requirements prescribed. The product shall conform to the prescribed mechanical property requirements. The product shall conform to the prescribed bend testing requirements. The test specimens of material designated as Copper UNS Nos. C10100, C10200, C10300, C10400, C10500, C10700, and C12000 shall be free of cuprous oxide. When tested, material designated as Copper UNS nos. C10100, C10200, C10300, C10400, C10500, C10700, and C12000 shall pass the embrittlement test. The product shall be passed through an eddy-current testing unit adjusted to provide information on the suitability of the product for the intended application.
SCOPE
