3、e of alloy UNS Nos.C49255, C49260, C49300, C49340, C49350, C49355, and C49360 intended for use in plumbing applications and drinking watersystems.1.2 Typically, rod and bar product made to this specification is furnished as straight lengths. Wire (H04) 0.08-0.3 in. 2-8 mminclusive is furnished in co
4、il form, and H50 shapes.1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values statedin each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining valuesfrom the two systems may
5、 result in non-conformance with the standard.1.4 The following safety hazard caveat pertains only to the test method(s) described in this specification.1.4.1 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of

Chemical Composition7.1 The material shall conform to the chemical composition requirements in Table 1 for the
23、copper alloy UNS Numbersspecified in the ordering information.7.2 These composition limits do not preclude the presence of other elements. By agreement between the manufacturer andpurchaser, limits may be established and analysis required for unnamed elements.7.3 For alloys in which zinc is listed a
24、s “remainder,” either copper or zinc may be taken as the difference between the sum ofresults of all elements determined and 100 %. When all elements in Table 1 are determined, the sum of results shall be 99.5 %min.TABLE 1 Chemical Composition, %Copper AlloyUNS No.Copper LeadmaxIronmaxTin Zinc Phosp
