1.1 This specification covers bare bunch-stranded and rope-lay bunch-stranded conductors made from round copper wires finer than No. 40 AWG with diameters less than 0.0031 in. (.078 mm), either coated or uncoated with tin or silver, for use as electrical conductors. (Explanatory Note 1).
1.2 The values (SI units) for density and temperature are regarded as the standard. For all other properties the inch-pound values are to be regarded as standard, and the SI units may be approximate.
