Materials and Manufacture4.1 Materials:4.1.1 The mater
37、ials shall conform to the published compo-sitional requirements of the Copper or Copper Alloy UNS No.designation specified in the ordering information.4.1.2 In the event heat identification or traceability isrequired, the purchaser shall specify the details desired.NOTE 2Because of the discontinuous
38、 nature of the processing ofcastings into wrought products, it is not always practical to identifyspecific casting analysis with a specific quantity of finished material.4.2 ManufactureThe product shall be produced by hotworking, cold working, or both, and finished by such coldworking, annealing or
39、heat treatment and straightening as maybe necessary to meet the properties specified.4.2.1 EdgesThe edge shall be drawn, extruded, or rolled;refer to Edge Contours in Section 6.5. Chemical Composition5.1 The material of manufacture shall conform to thecompositional requirements prescribed in the pro
40、duct specifi-cation.5.1.1 When a product (check) sample is analyzed by thepurchaser, the material shall conform to the compositionalrequirements within the permitted analytical variance given inthe product specification.5.2 The composition limits established for the Copper orCopper Alloy UNS No. des
41、ignation specified in the productspecification does not preclude the presence of other elements.Limits may be established and analysis required for unnamedelements by agreement between the manufacturer or supplierand the purchaser.5.3 When material composition has been determined duringthe course of
42、 manufacture, analysis of the finished product bythe manufacturer is not required.6. Dimensions, Mass and Permissible Variations6.1 GeneralFor the purpose of determining conformancewith the dimensional requirements, any measured value out-side the specified limiting values for any dimension may beca
