Bunched Cable Vertical Flame Spread Tester in Accordance with EN 50399 and IEC 60332-3-10.

For testing the vertical installation of a bunched power, control or fiber optic cable to suppress vertical spreading of the flame under specified conditions. Most important parameters, such as the heat release and smoke production during flame spread tests under fire condition are in accordance with EN 50399 and IEC 60332-3-10.

Fire tests are important for determining the behavior of cables in the case of fire. Single flame testing is the minimum performance requirement specified in the standards. The objective of these tests is to verify the flame spread characteristics of both the material and the cable construction.

The Construction Products Regulation (CPR) assigns a fire classification based on how well cables perform in fire tests in accordance with EN 50399, EN 60332-1-2, EN 61034-2 and EN 60754-2. Classifications are then made from Aca (non-flammable) to Fca (the lowest, no requirements).
