    1. Scope

    1.1 This specification covers stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead alloy for general use in insulated conductor assemblies for electrical purposes. These conductors shall be composed of one or more roller shaped or die closed layers of helically laid wires using the single input wire (SIW) methodology. (see Note 1 and Explanatory Note 1)

    Note 1

    Sealed conductors which are intended to prevent longitudinal water propagation and are further covered/insulated, are also permitted within the guidelines of this specification.

    1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

    1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.
