Terminology3.1 For definitions of terms related
26、to copper and copper alloys, refer to Terminology B846.3.2 Definitions of Terms Specific to This Standard:3.2.1 lengths, mill, nstraight lengths, including ends, that can be conveniently manufactured in the mill. Full length pieces areusually 10 or 12 ft 3000 or 3600 mm.3.2.2 lengths, stock, nstraig
27、ht lengths that are mill cut and stored in advance of orders. They are usually 10 or 12 ft 3000 or3600 mm and subject to established length tolerances.4. Materials and Manufacture4.1 Materials:4.1.1 The material of manufacture shall be a form of the Copper or CopperAlloy UNS No. designation specifie
