23、erms related to copper and copperalloys, refer to Terminology B846.3.2 Definitions of Terms Specific to This Standard:3.2.1 lengths, mill, nstraight lengths, including ends, thatcan be conveniently manufactured in the mill. Full lengthpieces are usually 10 or 12 ft 3000 or 3600 mm.3.2.2 lengths, sto
24、ck, nstraight lengths that are mill cut andstored in advance of orders. They are usually 10 or 12 ft 3000or 3600 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 theCopper or Copper Alloy UNS No. designatio

Chemical Composition5.1 The material shall conform to the chemical compositionrequirements prescribed in the product specification.5.1.1 Results of analysis on a product (check) sample shallconform to the composition requirements within the permitted
29、analytical variance given in the product specification.5.2 The composition limits established for the Copper orCopper Alloy UNS No. designation specified in the productspecification do not preclude the presence of other elements.By agreement between the manufacturer or supplier and thepurchaser. Lim
30、its may be established and analysis required forunnamed elements.5.3 When material composition has been determined duringthe course of manufacture, analysis of the finished product bythe manufacturer is not required.6. Dimensions, Mass and Permissible Variations6.1 GeneralFor the purpose of determin
31、ing conformancewith the dimensional requirements, any measured value out-side the specified limiting values for any dimension may because for rejection.6.1.1 The dimensions and tolerances for products refer-enced to this specification, shall be as noted in the followingparagraphs and tables, where t

The deviation from straightnessshall not exceed the limitations specified in Table 16 for eithergeneral or automatic screw machine use for the productspecifications and alloys shown in the tab
41、le titles. To determinecompliance with this tolerance, the lengths shall, in case ofdisagreement, be checked by the following method:6.4.1.1 Place the lengths on a level table so that the arc ordeparture from straightness is horizontal.
