Die Annotation des Normtextes ASTM B174-17(2024) :

This specification covers bare bunch-stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead-alloy for use as electrical conductors. Coated wires shall include only those wires with finished diameters and densities substantially equal to the respective diameters and densities of uncoated wires. Bunch-stranded conductors are classified as Class I, Class J, Class K, Class L, Class M, Class O, Class P, and Class Q, according to wire diameter. Requirements for conductor joints, lay length, wires, and strand construction are given. Electrical and elongation tests of wires composing the conductors shall be performed. If a tinning, lead-coating, or lead-alloy-coating test is required, it shall be made on the wires prior to stranding. The methods of determining mass, cross sections, and electrical resistance are detailed. The density of copper to be taken in the calculations is prescribed.
