Anotation

This specification deals with bare fine-wire bunch-stranded and rope-lay bunch-stranded copper conductors made from round copper wires finer than No. 40 AWG, either coated or uncoated with tin or silver, for use as electrical conductors. The conductor types covered in this specification are designated Type B for bunch-stranded conductors, and Type R for rope-lay bunch-stranded conductors. On the other hand, the wire classifications are assigned as: Class R, stranded conductors using wire 42 AWG; Class S, stranded conductors using wire 44 AWG; Class T, stranded conductors using wire 46 AWG; Class U, stranded conductors using wire 48 AWG; and Class V, stranded conductors using wire 50 AWG. Wires shall undergo tests that shall evaluated their conformance to physical and electrical properties such as wire cross-sectional area and diameter, coating thickness, tensile strength, elongation, and DC resistance.
