Standard Specification for Copper, Bus Bar, Rod, and Shapes and General Purpose Rod, Bar, and Shapes
N B187/B187M
Annotation
This specification2 establishes the requirements for copper conductor bar, rod, and shapes for electrical (bus) applications and rod, bar, and shapes for general applications.
The products for electrical (bus) applications shall be made from the following coppers:3
The product may be furnished from any copper listed unless otherwise specified in the contract or purchase order.
The product for general applications shall be made from any of the coppers in 1.1.1 or the following coppers:
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.
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.
NOTE 1—Material for hot forging will be found in Specification B124/B124M.
2 For ASME Boiler and Pressure Vessel Code applications, see related Specification SB-187 in Section II of that Code.
3 Refer to Practice E527 for an explanation of the Unified Numbering System.
