1.1 This specification establishes requirements for round, hexagonal, octagonal, rectangular and square brass wire of UNS Alloy Nos. C21000, C22000, C22600, C23000, C23400, C24000, C26000, C27000, and C27400.
1.2 Units—The values stated in either SI units or inch- pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equiva- lents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1.15 Supplementary Requirements
3.2 In addition, when a section with a title identical to that referenced in 3.1 appears in this specification, it contains additional requirements that supplement those that appear in Specification B250/B250M.
4. Terminology
4.1 Definitions ofTerms Specific to This Standard: 4.1.1 camber offset, n—the axial component of curvature of wire in an unrestrained state. 4.1.1.1 Discussion—The camber is measured as the offset in the ends of one turn of freely hanging wire. 4.1.2 cast, n—the maximum diameter of coiled wire when one complete circumference rests completely on a flat surface as a table, workbench, or floor. 4.2 For other definitions of terms related to copper and copper alloys, refer to Terminology B846.
5. Ordering Information
5.1 Include the following information in orders for product: 5.1.1 ASTM Designation and year of issue; 5.1.2 Copper Alloy UNS No. designation; 5.1.3 Temper; 5.1.4 Cross section: round, hexagonal, octagonal, rectangular, or square; 5.1.5 Quantity: total weight, footage, or number ofpieces of each temper, cross section, or alloy; 5.1.6 Dimensions: diameter or distance between parallel surfaces, width and thickness, length;5.1.7 Type of edge: square corners, rounded edge, full- rounded edge; 5.1.8 How furnished: coil, spool, or reel, specific lengths with or without ends; and 5.1.9 When material is purchased for agencies of the U.S. government (Specification B250/B250M). 5.2 The following options are available to this specification and should be specified in the contract or purchase order when required: 5.2.1 Certification (Specification B250/B250M, and 5.2.2 Mill test report (Specification B250/B250M. 5.2.3 Cast and camber requirements, if specified.
6. Materials and Manufacture
6.1 Material—The material shall be made from cast billets, logs, or rods of Copper Alloy UNS Nos. C21000, C22000, C22600, C23000, C23400, C24000, C26000, C27000, or C27400, of such purity, soundness, and structure to be suitable for processing into the desired product. 6.2 Manufacture—The products shall be manufactured by such hot working, cold working, and annealing processing as to produce a uniform wrought structure in the finished product.
8. Temper
8.1 The product in drawn or rolled wire of UNS Alloy Nos. C21000, C22000, C22600, C23000, C23400, C24000, C26000, C27000, and C27400 shall be available in H00, H01, H02, H03, H04, H06, H08, and H10 tempers as defined in Classification B601. 8.1.1 Product made in H04 temper is not generally available in sizes over 1 ⁄ 2 in. [13 mm] in diameter. 8.1.2 Product made in H06 temper is not generally available in sizes over 3 ⁄ 8 in. [10 mm] in diameter. 8.1.3 Product made in H08 temper is not generally available in sizes over 1 ⁄ 4 in. [6 mm] in diameter. 8.1.4 Square product is not generally available in H06 or H08 tempers. 8.1.5 The tension test shall be the standard temper test for all H temper wire. 8.1.6 The product in annealed form of UNS Alloys Nos. C21000 and C22000 shall be available in OS050, OS035, OS025, and OS015 tempers as defined in Classification B601. 8.1.7 The product in annealed form of UNS Alloy Nos. C22600, C23000, C23400, and C24000 shall be available in OS070, OS050, OS035, OS025, OS015, and OS010 tempers as defined in Classification B601. 8.1.8 The product in annealed form of UNS Alloy Nos.

9. Grain Size for Annealed Wire
9.1 Grain size shall be the standard requirement for all product in the annealed tempers. 9.2 Acceptance or rejection based on grain size shall depend only on the average grain size of test specimens taken from each oftwo sample portions and each specimen shall be within the limits prescribed in Table 2 when determined in accordance with Test Methods E112.
