Standard Specification for Copper-Clad Aluminum Bar for Electrical Purposes (Bus Bar)
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the manufacturing and testing requirements for copper clad aluminum rectangular bar for electrical (bus) applications. Six classes of copper-clad aluminum bar are covered:
Class 20A—Nominal 20 volume % copper, annealed.
Class 25A—Nominal 25 volume % copper, annealed.
Class 30A—Nominal 30 volume % copper, annealed.
Class 20H—Nominal 20 volume % copper, hard-worked.
Class 25H—Nominal 25 volume % copper, hard-worked.
Class 30H—Nominal 30 volume % copper, hard-worked.
The products covered by this specification shall consist of a solid core of aluminum with a continuous outer copper layer bonded to the core throughout. This specification also covers information that shall be included in orders for materials, the responsibility of the producer for inspection and tests, tensile properties, bend properties, interface bonding, density, electrical properties, edge contours, dimensional tolerances, source inspection, retest, certification, and packaging and package marking.
Scope
1.1 This specification covers copper clad aluminum rectangular bar for electrical (bus) applications.
1.2 Six classes of copper-clad aluminum bar are covered as follows:
Class 20A—Nominal 20 volume % copper, annealed.
Class 25A—Nominal 25 volume % copper, annealed.
Class 30A—Nominal 30 volume % copper, annealed.
Class 20H—Nominal 20 volume % copper, hard-worked.
Class 25H—Nominal 25 volume % copper, hard-worked.
Class 30H—Nominal 30 volume % copper, hard-worked
1.3 The values stated in inch-pound units are to be regarded as the standard, except for resistivity and density, where the SI units are the standard. The values given in parentheses are for information only.
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.
