EN 50399 specifies the apparatus and methods of test for the assessment of vertical flame spread, heat release, smoke production and occurrence of flaming droplets/particles of vertically-mounted electric cables under defined conditions. NOTE For the purpose of this standard, the term “electric cable” covers all power, control and communication cables, including optical fibre cables and hybrid cables used for the conveyance of energy and/or signals. EN 50399 details the apparatus for the fire propagation testing and the arrangement and calibration of the instrumentation to be installed in order to measure the heat release and the smoke production during the test. The combustion gases are collected in a hood above the test chamber and conveyed through an exhaust system, which allows the measurement of heat release rate and smoke production. Test procedures to be used for type approval testing for classification of cables in classes [2, 6] B1ca, B2ca, Cca and Dca are given. Cable installation on the test ladder and the volume of air passing through the chamber are in accordance with the Commission Decision 2006/751/EC [5], which is reflected in the requirements of this standard.
