Fecha:

Abstract:

This specification establishes the requirements for copper conductor bars, rods, and shapes for both electrical (bus) and general applications. Products shall be produced in tempers O60 (soft annealed), and H04 (hard). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, diameter, thickness, width, shape, specified and stock lengths, straightness, edge contour, and radius of edges or corners), mechanical (tensile, yield and bend strengths, elongation, Rockwell hardness, and embrittlement), electrical resistivity, and chemical composition requirements.

Scope:

1.1 This specification2 establishes the requirements for copper conductor bar, rod, and shapes for electrical (bus) applications and rod, bar, and shapes for general applications.

1.1.1 The products for electrical (bus) applications shall be made from the following coppers:3

1.1.1.1 The product may be furnished from any copper listed unless otherwise specified in the contract or purchase order.

1.2 The product for general applications shall be made from any of the coppers in 1.1.1 or the following coppers:

Copper UNS No.3

Reference Designation

 

C10800

 OFLP

C12200

DHP

1.2.1 The product may be furnished from any copper listed above unless otherwise specified in the contract or purchase order. Other coppers may be used upon agreement between the supplier and purchaser.

1.3 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.

Note 1: Material for hot forging will be found in Specification B124/B124M.

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.
