1.1 This specification covers tin-coated hard-drawn copper braid and ribbon flat wire intended for electronic application (Explanatory Note 1).

1.2 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.

1.2.1 Exceptions—The SI values for density, resistivity, and volume are to be regarded as standard.

1.3 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 covers tin-coated hard-drawn copper braid and ribbon flat wire intended for electronic application. The tin shall be electroplated for the coating and shall be commercially pure. For purposes of this specification, the tin shall be considered commercially pure if the total of other elements, exclusive of copper, does not exceed 1%. This specification covers electrical resistivity requirements, permissible variations in thickness, permissible variations in width, and limiting number of test specimens for coating test.
