Corrosiveness of the combustion gases (absence of halogen) Determination of Acidity IEC 60754-1/EN 50267-2-1 Test set-up : A sample of between 0.5g and 1g is heated in a tube. The resulting gases are dissolved and tested for their halogen content. Test apparatus according to EN 50267-1. Flame temperature : 800°C ±10°C Test duration : 40 ±5 minutes in total, with at least 20 minutes at the maximum temperature. Compliance criterion : The amount of halogen acid is expressed as mg of hydrochloric acid per gram mass of sample.

materials that contain no halogens, and the other for those that include a high percentage of halogens, with the most common being chlorine, fluorine and bromine. The below table illustrates the halogen content in typical insulation and jacket materials:

Test set-up : A cable specimen is burnt in a closed chamber using a flammable liquid. The light transmittance of the resulting smoke is measured optically. Test apparatus according to IEC/EN 61034-1. Flame temperature : Determined by the quantity and

Why use Alfanar LSHF cables and wires? • Green, safe and healthy : They offer the added benefit of being more environmentally friendly • Halogen-free products : They eliminate the threat of forming caustic acids (such as hydrochloric acid) and contribute to less corrosion damage to equipment near the fire • No emission of toxic gases : They eliminate the threat of inhaling toxic gases and reduce damage to the human respiratory system • Reduction of smoke emission to a minimum : No release of dense smoke that impairs visibility of the fire exit routes and hampers rescue operations • Resistant to ignition : It takes much more time than traditional cables to catch fire, which facilitates the evacuation procedure • Reduction of flame propagation : Their excellent flame-retardant property prevents the fire from spreading • Easy to install : LSHF jackets have a lower coefficient of friction than some non-LSHF jackets, which can make cable installation easier

composition of the fuel. Test duration : 40 minutes.

Compliance criterion : The smoke must transmit the light at the end of the test duration, as stated in individual specifications. The recommendation of light transmission is 60 per cent minimum.
