    1. Scope

    1.1 This specification covers tin-coated copper-clad steel wire for electronic application.

    1.2 Four classes of tin-coated copper-clad steel wire are covered as follows:

    1.2.1 Class T30HS—Nominal 30 % conductivity, hard-drawn,

    1.2.2 Class T30A—Nominal 30 % conductivity, annealed,

    1.2.3 Class T40HS—Nominal 40 % conductivity, hard-drawn, and

    1.2.4 Class T40A—Nominal 40 % conductivity, annealed.

    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—The SI values for resistivity and volume are to be regarded as standard.

    1.4 The following safety hazards caveat pertains only to the test method portion, Section 6, 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. (Warning—Consideration should be given to toxicity and flammability when selecting solvent cleaners.)
