This International Standard is applicable to, and specifies requirements for, resistive heating cables for low temperature applications such as comfort heating and the prevention of ice formation. These cables and cable sets may comprise either factory fabricated or field (worksite) assembled units, and which are heating cables assembled in accordance with manufacturer’s instructions. Bare conductors and protected conductors to be supplied at voltages equal to, or less than, 50 V are excluded from the scope of this standard. NOTE Terminations and gland fittings are outside the scope of this standard. Typical applications include, but are not limited to: • surface heating installed in or under surfaces; • direct and storage heating; • snow melting and frost protection of roofs, gutters, pipes, etc. Heating cables for industrial and commercial applications are specified in the IEC 62395 series [1]1 as are mineral insulated heating cables. Applications in which the operating sheath temperature exceeds 100 °C are outside the scope of this standard. The object of this standard is to ensure that electrical resistance heating cables operate safely under their normal defined conditions of use. This is achieved by: – employing heating cables of the appropriate construction that meet the test criteria detailed in this standard; – including, for cables with an electrical protective component, a metallic braid, concentric wires or sheath, or other suitable electrically conductive material for protective purposes in case of fault; – ensuring that the cables operate at safe temperatures with respect to the materials used in the construction of the cables and their installations according to national regulations.
