1、Designation: B 99/B 99M 06Standard Specification forCopper-Silicon Alloy Wire for General Applications1This standard is issued under the fixed designation B 99/B 99M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last
2、 revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification establishes the requ
3、irements forround, rectangular, and square wire for general applicationsother than for electrical transmission cable. The alloys in-volved are UNS Nos. C65100 and C65500.1.2 UnitsThe values stated in inch-pound units or SI unitsare to be regarded separately as standard. Within the text, SIunits are
4、shown in brackets. The values stated in each systemmay not be exact equivalents; therefore, each system shall beused independently of the other. Combining values from thetwo systems may result in nonconformance with the standard.2. Referenced Documents2.1 ASTM Standards:2B 250/B 250M Specification f
