Thevalues stated in each system may
5、 not be exact equivalents;therefore, each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsib
6、ility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.

19、esignated copper or copper-alloy of such purityand soundness to be suitable for processing in to the productsprescribed herein.5.1.2 In the event that heat identification or traceability isrequired, the purchaser shall specify the details desired.NOTE 2Due to the discontinuous nature of the processi
20、ng of castingsinto wrought products, it is not always practical to identify a specificcasting analysis with a specific quantity of finished material.5.2 Manufacture:5.2.1 The product shall be manufactured by such hot work-ing, cold working, and annealing processes as to produce auniform wrought stru
21、cture in the finished product.5.2.2 The product shall be hot or cold worked to the finishedsize and subsequently annealed, when required, to meet thetemper properties specified.6. Chemical Composition6.1 The material shall conform to the chemical compositionrequirements in Table 1 for the copper or
22、copper alloy UNSNo. designation specified in the ordering information.6.1.1 These composition limits do not preclude the presenceof other elements. By agreement between the manufacturer andthe purchaser, limits may be established and analysis requiredfor unnamed elements.6.2 For alloys in which eith
23、er copper or zinc is listed as“remainder,” copper or zinc is the difference between the sumof results of all elements determined and 100 %. When allelements in Table 1 for the specified copper-alloy are deter-mined, the sum of results shall be as follows:Copper Alloy UNS No. Sum of Results,%minC3650
