1、Designation: B99/B99M 11B99/B99M 15Standard Specification forCopper-Silicon Alloy Wire for General Applications1This standard is issued under the fixed designation B99/B99M; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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 establish
3、es the requirements for round, rectangular, and square wire for general applications other thanfor electrical transmission cable. The alloys involved are UNS Nos. C65100 and C65500.1.2 UnitsValues The values stated in either inch-pound units or SI units are to be regarded separately as standard. Wit
4、hin thetext, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shallbe used independently of the other. Combining values from the two systems may result in nonconformance with the standard.2. Referenced Documents2.1 ASTM Standards:2
