EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62821-1 test. IEC EN 62821-1 is valid for insulated and, if any, sheathed cables with rated voltages up to and including 450/750 V used, halogen-free, based on thermoplastic compounds and having low emission of smoke and corrosive gas when exposed to fire.
Cables shall be provided with an indication of the manufacturer, such as an introductory thread or a repeating mark of the manufacturer's name or trademark. Cables to be used at a conductor temperature exceeding 70°C will also be marked with the code definition or the maximum conductor temperature. The marking may be by printing or embossing reproduction on the insulation of an unsheathed cable or on the sheath.
Identification of the cores of a cable should be done using colored insulation or another suitable method. Each core of a cable will have only one color, except for the core identified by the combination of green and yellow colors. The green and yellow colors should not be used for any multicore cable unless they are in combination.
The insulation of the cores shall be of the same color and numbered sequentially, except for the green and yellow colored cores, if any. Numbers will be printed on the outer surfaces of the hubs with Arabic numerals. All numbers shall be of the same colour, contrasting with the color of the insulation. Numbers will be legible.
The conductors shall consist of annealed copper, except for tinsel cord wires, where a copper alloy may be used. Wires can be plain or tinned.
The insulation should be applied so that it fits snugly to the conductor, but for cables other than tinsel, it should be possible to remove the insulation without damaging the insulation itself, the conductor, or the tin coating, if any. Unless otherwise specified in certain sections, it is allowed to place a separator between the conductor and the insulation.
