Scope*1.1 This specification establishes the requirements forcopper-zinc-tin-bismuth alloy rod, bar and wire of alloy UNSNos. C49260,
3、 C49300, C49340, and C49350 intended for usein plumbing applications and drinking water systems.1.2 Typically, rod and bar product made to this specificationis furnished as straight lengths. Wire (H04) 0.08-0.3 in. 2-8mm inclusive is furnished in coil form, and H50 shapes.1.3 UnitsThe values stated
4、in either SI units or inch-pound units are to be regarded separately as standard. Thevalues stated in each system may 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.1.4 The
5、 following safety hazard caveat pertains only to thetest method(s) described in this specification.1.4.1 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and hea
