ASTM B197/B197M-20e1

Standard Specification for Copper-Beryllium Alloy Wire

1.1This specification establishes the requirements for copper-beryllium alloy wire in coils, spools, or other than straight lengths, of any uniform cross section. Copper Alloy UNS Nos. C17200 and C173002 are included.

1.2Unless otherwise required, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B197/B197M is specified without any alloy designation.

1.3The values stated in either inch-pounds units or SI units are to be regarded separately as standard. Within the text, the 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.

1.4The following safety hazard caveat pertains only to the test methods described in this specification:

1.4.1This 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.

1.5This 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.
