This specification covers tin-coated annealed copper wire intended for electrical and electronic applications where solderability is a requirement. The tin shall be electroplated for the coating and shall be commercially pure. The base metal shall be copper of such quality and purity that the finished product shall have properties and characteristics prescribed. Tensile strength and elongation, resistivity, dimensional measurements, continuity of coating, thickness of coating, and solderability test methods shall be performed to conform to the requirements specified.

1.1 This specification covers tin-coated annealed copper wire intended for electrical and electronic applications where solderability is a requirement.

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 and health practices and determine the applicability of regulatory limitations prior to use.
