1、Designation: B 134/B 134M 05Standard Specification forBrass Wire1This standard is issued under the fixed designation B 134/B 134M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses i
2、ndicates 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 requirements for round,hexagonal, octagonal,
3、 rectangular and square brass wire ofUNS Alloy Nos. C21000, C22000, C22600, C23000, C23400,C24000, C26000, C27000, and C27400.1.2 UnitsThe values stated in either inch-pound or SIunits are to be regarded separately as standard. Within the textand tables, the SI units are shown in brackets. The value
4、s statedin each system may not be exact equivalents: therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in nonconformancewith the standard.2. Referenced Documents2.1 ASTM Standards:2B 250/B 250M Specification for General Requirements forWr
