The EN 50399 was based on IEC 60332-3 with the addition of heat release measurement and a modified air inlet system. This is accomplished by fitting a small instrumented section of ducting into the exhaust system of the rig and using this with associated FTT gas analysis instrumentation and software. The duct section houses all gas sampling probes, temperature…
