A number in parenth
2、eses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification establishes the requirements for roundand flat
3、 (square and rectangular) phosphor bronze wire of UNSAlloy Nos. C51000, C52100, and C52400 for general andspring applications.1.1.1 Rectangular and square wire of the three alloys aregenerally available in sizes up to a maximum of 0.188 in.5 mm thick and 1.250 in. 32 mm wide.1.1.2 Round wire from Co
4、pper Alloy UNS No. C51000 isgenerally available in sizes up to 0.500 in. 13 mm indiameter.1.2 UnitsThe values stated in either inch-pound units or inSI units are to be regarded separately as standard. Within thetext, the SI units are shown in brackets. The values stated ineach system may not be exac
5、t equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the specification.1.3 Additional requirements for these products are estab-lished in Specification B250/B250M, see Section 3.1.4 This standard does no
6、t 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, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.NOTE 1It is to be unders
7、tood that this specification is general. Sincethe product is used for many applications where the requirements of theoperations used are too particular to be specified by any of the ordinarymechanical tests, it is frequently advisable to submit samples or drawingsto the manufacturer and secure an ad
8、justment of temper to suit the actualapplication for which the product is intended.NOTE 2Product in rod, bar and shape form is produced to Specifica-tion B139/B139M.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established
