Historical (view previous versions of standard)
This specification establishes the requirements for wrought forms and fabricated shapes of oxygen-free copper with UNS No. C10100 suitable for use in electron devices. Specimens shall be appropriately sampled and shall undergo hydrogen embrittlement (reverse bend) test, special macro examination, and special microscopical examination. Materials shall adhere to specified mechanical, dimensional, chemical composition, electrical resistivity, and grain size requirements.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification establishes the requirements for wrought and fabricated shapes made from Copper UNS No. C10100, conforming to the chemical requirements of Specification B170, Grade 1, and suitable for use in electron devices.
1.2 The requirements of this specification are in addition to those prescribed in the following product specifications appropriate to the material being ordered: B1, B2, B3, B75, B75M, B152/B152M, B170, B187/B187M, , B272, and B372. In case of conflict, however, this specification shall take precedence.
1.3 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.
1.3.1 Exception—grain sizes are in metric units and are standard.
1.4 The following safety hazard caveat applies to sections 17.4, 17.5 and 18.7 of this specification: 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 and health practices and determine the applicability of regulatory limitations prior to use.
