Standard Specification for Copper Sheet, Strip, Plate, and Rolled Bar
This standard covers the requirements for copper sheet, strip, plate, and rolled bar produced from copper with the following UNS Nos.; C10100, C10200, C10300, C10400, C10500, C10700, C10800, C10910, C11000, C11300, C11400, C11600, C12000, C12200, C12300, C14200, C14420, and C14530. Chemical composition shall conform to the chemical requirements pertaining to the materials UNS No. Tempering of materials shall be done by hot-rolling, cold rolling, and annealing. Copper material shall meet the maximum limit of electrical resistivity as indicated. The material shall undergo tensile strength, Rockwell hardness, and plate item tests to conform with the mechanical proptery requirement of the specification. The material shall also be capable of passing microscopical examination and embrittlement test, but not required by the specification.
1.1 This specification2 establishes the requirements for copper sheet, strip, plate, and rolled bar produced from the following coppers.
Copper UNS No.A
Type of Copper

Note 1: Each of the coppers listed has unique properties that can make it suitable for specific applications. The purchaser should consult with the supplier to determine which copper would be best suited for the intended application.
Note 2: This specification is not intended to establish requirements for material rolled to ounce-weight thicknesses. Such material is defined in Specification B370. Flat copper products with finished (rolled or drawn) edges (flat wire and strip) are defined in Specification B272.
1.1.1 When a specific copper is not identified in the contract or purchase order, the supplier may furnish product from any of the listed coppers.
1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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 The following safety hazard caveat pertains only to the test method(s) described in this specification:
1.3.1 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
