EN50399 cable flame spread / heat release and smoke test

EN50399 standards
The EN50399 standard specifies test equipment and test methods for the evaluation of flame spread, heat release, and smoke generation characteristics of vertically mounted bunched wires, cables, or optical cables under specified test conditions. In the EN50399 test, the cable is installed on the vertical standard ladder, and the ignition of the ignition point is adopted to evaluate the combustion behavior and combustion performance of the cable. Through the EN50399 test can obtain cable fire early stage combustion performance data, through the heat release rate test of flame spread along the cable danger and fire source potential impact on adjacent areas, through the dangerous area of the fire smoke density test of visibility and smoke on personal safety caused by.

EN 50399:2011+A1:2016 Common test methods for cables under fire conditions-Heat release and smoke production measurement on cables during flame spread test-Test apparatus procedures, results.

EN50399 cable performance test
Flame spread, heat release rate, total heat release rate, smoke production rate, total smoke production rate, burning growth rate index, and the dropping of the particles.

EN50399 cable performance test requirements
Test according to EN 50399 standard, each cable sample length of not less than 3.5m, non-metallic materials to 1.5l/ M. This standard also carries on the total heat release (THR) of the cable and the smoke discharge volume test (TSP).
The total heat release (THR) and smoke emission (TSP) of the cable are calculated according to the formula in EN 503099 standard.

EN50399 Burning behaviour and smoke production of bunched cable
For smoke production, the test is relevant for B1ca, B2ca, Cca and Dca in association with additional classification s.
This test evaluates the potential contribution of a cable, installed with other cables, to the development of a fire, under direct exposure to a flame source.
The test is relevant for the class B1ca using a 30KW flame source and special mounting requirements.
The test is relevant for the classes B2ca and Dca using a 20.5KW flame source.

EN13501-6 standard according to the cable heat release amount, the length of the destruction of fire and so on the flame of the cable is divided into seven levels: EN13501-6 Aca, B1ca, B2ca, Cca, Dca, Eca, Fca these seven levels.
