A numb
2、er in parentheses 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
3、round, square round and flat (square and rectangular) phosphor bronzewire of UNS Alloy Nos. C51000, C52100, and C52400 for general and spring applications.1.1.1 Rectangular and square wire of the three alloys are generally available in sizes up to a maximum of 0.188 in. 5 mm5 mm thick and 1.250 in.
4、32 mm wide.1.1.2 Round wire from Copper Alloy UNS No. C51000 is generally available in sizes up to 0.500 in. 13 mm in diameter.1.2 UnitsValues The values stated in either inch-pound units or in SI units are to be regarded separately as standard. Withinthe text, the SI units are shown in brackets. Th
5、e values stated in each system may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining values from the two systems may result in non-conformance with thespecification.1.3 Additional requirements for these products are established in Specification B250/
6、B250M, see Section 3.1.4 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 this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of reg
7、ulatory limitations prior to use.NOTE 1It is to be understood that this specification is general. Since the product is used for many applications where the requirements of theoperations used are too particular to be specified by any of the ordinary mechanical tests, it is frequently advisable to sub
8、mit samples or drawings to themanufacturer and secure an adjustment of temper to suit the actual application for which the product is intended.NOTE 2Product in rod, bar and shape form is produced to Specification B139/B139M.1.5 This international standard was developed in accordance with internation
9、ally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standards, Guides and Recommendations issuedby the World Trade Organization Technical Barriers to Trade (TBT) Committee.2.
