ASTM B187/B187M-06

1.1 This specification 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:

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 or the following coppers:

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 supplier and purchaserer.

1.3 Units - The values stated in either inch-pound units or in SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

Material for hot forging will be found in Specification B 124/B 124M.

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.
