38、 the discontinuous 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 coldwork

39、ing, annealing or 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 pre

40、scribed in the product 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

41、 Alloy UNS No. designation 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 d

42、uringthe course of 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

43、dimension may because for rejection.NOTE 3Blank spaces in the tolerance tables indicate either that thematerial generally is not available or that no tolerances are established.6.2 Diameter or Distance Between Parallel SurfacesThediameter of round sections or the distance between parallelsurfaces in
