Anotace textu normy ASTM B189-05(2021) :
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.
Keywords:
copper electrical conductor, copper wire, electrical conductor, electrical conductor—copper, lead-alloy-coated copper wire, lead-coated copper wire, soft copper wire,, ICS Number Code 29.060.10 (Wires)

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. 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. |
