Standard Specification for Lead-Coated and Lead-Alloy-Coated Soft Copper Wire for Electrical Purposes — 6 стр.
Реферат

This specification covers the standard general requirements for lead-coated and lead-alloy-coated, round, soft or annealed copper wire for electrical purposes. The base metal shall be made of copper while the coating material shall be a commercially pure lead or a lead alloy which consists of lead, tin, and antimony elements. Ammonium persulfate test or sodium polysulfide-hydrochloric acid test shall be employed to determine the continuity of the coatings. The wire shall undergo dimensional measurements using a micrometer caliper with a vernier, as well as tension and resistivity tests. The specimen shall conform to the required tensile strength, elongation, and electrical resistivity specifications.

Область применения

1.1 This specification covers lead-coated and lead-alloy-coated, round, soft or annealed copper wire for electrical purposes.

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. The SI values for density and resistivity are to be regarded as the standard.

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. The hazard statement applies only to Section of this specification.
