"This specification establishes requirements for bronze castings for turntables@ movable bridges and bridge parts@ and bronze castings suitable for use in bridges and other structures for fixed and expansion bearings in which motion is slow and intermittent. The following Copper Alloys are specified: UNS No. C86300@ C90500@ C91100@ C91300@ and C93700. NOTE 1??Historically@ the alloys in this specification have been used in the applications listed in Appendix X1. Actual practice may vary.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values 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. This standard does not purport to address all of the safety concerns@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 The UNS system for copper and copper alloys (see Practice E 527) is a simple expansion of the former standard designation system accomplished by the addition of a prefix ""C"" and a suffix ""00."" The suffix can be used to accommodate composition variations of the base alloy. *A Summary of Changes section appears at the end of this standard."
