1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 The following safety hazard caveat pertains only to the test methods 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.


This specification establishes the requirements for strips and sheets of copper-cobalt-beryllium and copper-nickel-beryllium alloys with Copper Alloy UNS Nos. C17410, C17450, and C17460. The materials for manufacture shall be cast billets or slabs of such purity and soundness as to be suitable for processing by hot-working, cold-working, and annealing to produce a uniform wrought structure in the finished product, which shall be rolled to finished size and heat treated when required to meet temper properties. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, straightness, and edge contours), mechanical (tensile and yield strength, Rockwell hardness, and elongation), electrical conductivity, and chemical composition requirements.
