Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This specification establishes the requirements for flat copper wire and strip products, with rolled or drawn finished edges produced for general applications. Unless otherwise established by agreement between the manufacturer and purchaser, products shall be produced in UNS Copper Nos. C10100, C10200, C10300, C10500, C10700, C10800, C11000, C11040, C12200, and C14200. The material for manufacture shall be a billet, cake, wire bar, or rod suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in the annealed (O61) and cold worked (H00, H01, H02, H03, H04, H06, and H08) tempers. Products shall be tested and shall adhere to dimensional (thickness, width, length, straightness, and edge contour), mechanical (tensile strength, elongation, Rockwell hardness, bend angle, and hydrogen embrittlement susceptibility), electrical resisitvity, and chemical composition requirements.
1.1 This specification establishes the requirements for copper products, flat wire and strip, with rolled or drawn finished edges produced for general application.
1.1.1 The product is produced in UNS Copper Nos. C10100, C10200, C10300, C10500, C10700, C10800, C11000, C11040, C12200, and C14200 unless otherwise established by agreement between manufacturer and purchaser.
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
Note 1: When a copper other than that listed in is designated by the purchaser, the resulting product shall conform to the physical, mechanical, performance, dimensional, and tolerance requirements per agreement between the manufacturer and purchaser.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
