IEC 60800-2009 pdf Heating cables with a rated voltage of 300/500 V for comfort heating and prevention of ice formation
5 Requirement for marking The product shall be marked by printing, embossing or indenting on the sheath or on a label attached to the product or on a component inside the cable. NOTE 1 Embossing is not recommended on the insulation. A label shall be attached to the product in a permanent way and be clearly detectable to the electrical installer. NOTE 2 The label should preferably be attached to that part of the product which is clearly visible when unpacking the product, ready for installation. The marking shall at least contain: • identification of the manufacturer by name and or a symbol; • the type reference; • resistance per metre of cable at 20 °C in Ohms per metre if single or twin conductor series resistive cables, or for a parallel cable, power output in Watts per metre at a reference temperature. For series resistive cables with more than two conductors the resistance of each conductor shall be clearly marked; • mechanical classification; • the rated voltage for parallel heating cables or maximum operating voltage for series heating cables; • if applicable, “only for installation in concrete”. The distance between the end of one complete set of marks and the beginning of the next shall not exceed: – 550 mm, if the marking is on the sheath; – 275 mm, if the marking is on a component inside the cable.
7.3 Insulation The insulating materials used in heating cables shall be suitable for the intended use. This shall be verified by meeting the tests and the requirements given in this standard. The minimum average value of the insulation thickness shall be stated by the manufacturer, and measured according to IEC 6081 1 -1 -1 , and meet the minimum requirement specified in 8.3.4. 7.4 Electrically conducting screen When applicable and required, heating cables shall be provided with an evenly distributed electrically conductive metallic screen, or electrically conductive metallic sheath, tape or laminate or other suitable electrically conductive material. The metallic screen or electrically conductive material shall enable protection device(s) to operate as intended. NOTE 1 For cables without an electrically conducting screen, additional national requirements may apply. The resistance of the conductive sheath or screen, inclusive of a separate earthing conductor which shall be in contact with the sheath or screen, shall be not higher than the resistance of each conductor in the cable or higher than the resistance of a plain copper conductor having 0,5 mm 2 cross-sectional area as given for a class 1 conductor according to IEC 60228, whichever is the lesser. The combined resistance of any earthing conductor included with this screen or sheath shall not be greater than that of a 0,5 mm 2 copper conductor. A number of copper wires may be included in order to comply with the requirements. NOTE 2 In some countries, national regulations require the resistance to be less than that of 0,5 mm 2 copper conductors. Compliance shall be checked as described in 8.2.1 .
