IEC/TR 62602:2009, which is a technical report, specifies the nominal cross-sectional areas, in the range 20 AWG to 2 000 kcmil (0,52 mm2 to 1 010 mm2), for conductors in electric power cables and cords for a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid and stranded copper, aluminium and aluminium alloy conductors in cables for fixedinstallations and flexible copper conductors. This technical report is not intended to apply to conductors designed for use in cables intended for telecommunication or data transmission, winding wires or similar products. Unless indicated to the contrary in a particular clause, this technical report relates to conductors in finished cables and not to conductors made or supplied for inclusion into a cable. The annexes give supplementary information covering measurement of resistance (Annex A), temperature correction factors for resistance measurement (Annex B) and dimensional limits of circular conductors (Annex C).
