General technical information 3.4 Terms for Cables relating to their behaviour in case of fire Halogen free, no corrosive combustion gases Is the property of a cable to consist only of materials which generate none or only small quantities of corrosive gases in the case of fire. These gases have the result that in the event of fire, material goods are damaged without the direct effect of the fire. For freedom from halogens it is usually necessary to meet the requirements of the applicable standard, e.g. tests according to EN 50267, IEC 60754-2 or DIN VDE 0482-267. H is added to the code of these cables and if they are enhanced flame-retardant, the symbol FRH is added.
Flame-retardant ("self-extinguishing") Is the property of a cable to automatically extinguish itself within a certain time after ignition by using barely flammable materials. For flame retardancy it is usually necessary to meet the requirements of the applicable standard, e.g. the single cable test according to EN 50265, IEC 60332-1 or DIN VDE 0482-265. If these cables are also halogen-free, H is added to the code.
Enhanced flame-retardant ("reduced fire propagation") Is the property of a cable to severely limit the spread of flames beyond the local source of ignition in the event of fire. For enhanced flame retardancy it is usually necessary to meet the requirements of the applicable standard, e.g. the multi-cable test according to IEC 60332-3 Cat. C or EN 50266-2-4. The symbol FR is added to the code for these cables. If they are also halogen-free, FRH is added to the code.
Minimum smoke emission Is the property of a cable to generate only a minimal amount of smoke in the case of fire. For minimal smoke production it is usually necessary to meet the requirements of the applicable standard, e.g. testing according to EN 50268, IEC 61034 or DIN VDE 0482-268. In these tests the reduction in the permeability of light in a standardised room is measured during combustion of the cable.
Insulation integrity on exposure to flames (e.g. FE 180) Is the property of a low-fire-spread halogen-free cable to retain the dielectric strength (insulation capability) without mechanical stressing for a certain time in the event of fire. Thus, the insulation integrity of the individual cable is guaranteed for a certain time in the event of fire, but an exact determination of the duration of complete functional efficiency to be predicted in the event of fire is not necessarily given. For the insulation integrity it is usually necessary to meet the requirements of the applicable standard, e.g. testing according to IEC 60331 or DIN VDE 0472-814. The symbol FE is added to the code for these cables as well as the duration in minutes during which the dielectric strength is guaranteed on exposure to flames.
Functional integrity (e.g. E30, E90) Is the property of a cable installation to retain its functional capability for a certain time in the event of fire. It is important that the cable is not considered alone but the entire installation including the installation materials used (clamps, channels etc). For the functional integrity it isusually necessary to meet the requirements of the applicable standard, e.g. testing according to DIN/ÖNORM 4102-12. The symbol E is added to the code for these cables as well as the duration in minutes for which the functional integrity is guaranteed in the event of fire.
