This standard is issued under the ?xed designation B 99/B 99M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last 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 speci?cation establishes the requirements for round, rectangular, and square wire for general applications other than for electrical transmission cable. The alloys involved are UNS Nos. C65100 and C65500. 1.2 Units—The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 2.

designation speci?ed in the ordering information. 5.1.1 These compositional limits do not preclude the presence of other elements. When required, limits may be established and analysis required for unnamed elements by agreement between the manufacturer and the purchaser. 5.2 Copper listed as the remainder is the difference between the sum of results for all elements determined and 100 %. 5.3 When all elements listed in Table 1 for the Copper Alloy UNS No. prescribed in the ordering information are determined, the sum of results shall be 99.5 % min. 6. Temper 6.1 Tempers, as de?ned in Classi?cation B 601, available under this speci?cation are O61 (annealed), H00 (1?8 hard), H01 (1?4 hard), H02 (1?2 hard), H04 (full hard), and H08 (spring). 6.1.1 Product made to H04 (full hard) temper is generally not available in sizes larger than 0.500 in. [12 mm] in diameter or distance between parallel faces. 6.1.2 Product made to H08 (spring) temper is generally not available in sizes larger than 0.250 in.
