ASTM B99-15(R2021) pdf free download.Standard Specification for Copper-Silicon Alloy Wire for General Applications
1. Scope
1.1 This specification establishes the requirements for round, rectangular, and square wire for general applications other than for electrical transmission cable. The alloys in- volved are UNS Nos. C65100 and C65500. 1.2 Units—The values stated in either 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 are not necessarily exact equivalents; 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. General Requirements
3.1 The following sections of Specification B250/B250M constitute a part of this specification. 3.1.1 Terminology, 3.1.2 Materials and Manufacture, 3.1.3 Workmanship, Finish, and Appearance, 3.1.4 Sampling, 3.1.5 Number of Tests and Retests, 3.1.6 Specimen Preparation, 3.1.7 Test Methods, 3.1.8 Significance of Numerical Limits, 3.1.9 Inspection, 3.1.10 Rejection and Rehearing, 3.1.11 Certification, 3.1.12 Test Report, 3.1.13 Packaging and Package Marking, and 3.1.14 Supplementary Requirements. 3.2 In addition, when a section with a title identical to that referenced in 3.1, above, appears in this specification, it contains additional requirements that supplement those appear- ing in Specification B250/B250M.
4. Ordering Information
4.1 Include the following specified choices when placing orders for product under this specification, as applicable: 4.1.1 ASTM designation and year of issue, 4.1.2 Copper Alloy UNS No.; 4.1.3 Temper (Section 6), 4.1.4 Dimensions (diameter, distance between parallel surfaces, width, and thickness); 4.1.5 How furnished (coil, reel, and so forth); 4.1.6 Total weight of each size; and 4.1.7 Intended application. 4.2 The following options are available but may not be included unless specified at the time of placing of the order when required: 4.2.1 Heat identification or traceability details (see 4.1.2 of Specification B250/B250M), 4.2.2 Certification, 4.2.3 Test reports, 4.2.4 Special packaging and package markings, and 4.2.5 If product is purchased for agencies of the U.S. government (see the Supplementary Requirements section of Specification B250/B250M).
5. Chemical Composition
5.1 The product shall conform to the chemical composition requirements in Table 1 for the Copper Alloy UNS No. designation specified in the ordering information. 5.1.1 These composition limits do not preclude the presence ofother elements. By agreement between the manufacturer and the purchaser, limits may be established and analysis required for unnamed elements. 5.2 For alloys in which copper is listed as “remainder,” copper is the difference between the sum of results for all elements determined and 100 %. 5.3 When all elements in Table 1 are determined, the sum of results shall be 99.5 % min.
6. Temper
6.1 The standard tempers for products described in this specification are given in Table 2. 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. [6 mm] in diameter or distance between parallel faces.
7. Grain Size for Annealed Temper
7.1 Grain size shall be the standard requirement for all product in annealed temper. 7.2 The average grain size of O61 (annealed) temper wire shall not exceed 0.040 mm, but the wire must be completely recrystallized. 7.3 Acceptance or rejection based upon grain size shall depend only on the average grain size of test specimens taken from each of two sample portions and each specimen shall be within the limits prescribed in 7.2 when determined in accor- dance with Test Methods E112.
