EN 50399: Common test methods for cables under fire conditions – Heat release and smoke production measurement on cables during flame spread test – Test apparatus, procedures, results
This test evaluates the potential contribution of a cable to the early stages of development of a fire, under direct exposure to a 20.5kW and 30kW flame source. The test is relevant for the classes B2ca, Cca, and Dca for 20.5kW and B1ca for 30kW.
The EN 50399 was based on IEC 60332-3 with the addition of heat release measurement and a modified air inlet system.
