NFF16-101-Railway rolling stock fire behavior choice of material
NF16-102-Railway rolling stock fire behavior choice of material –Electrical Equipment
As the cable flame spread and burning rate of destruction of the length of the combustion smoke density (light penetration) and the burning of hazardous toxic gas escape on the staff of life play a very important influence. In general, testing cables through these areas to assess。
NFF16-101/102 only testing for cable insulation, to assess the fire retardant properties of the cable. (Due to the metal conductor and the wire cable with non-flammable)
Cable testing for NFF16-101 Main standard the following:
I grade oxygen index test: I0-I4 (I0, I1, I2, I3, I4) according to EN 60695-2-11 (glow wire test) and EN 4589-2 (oxygen index test) together to assess the I-level oxygen index.
F-class smoke toxicity testing: F0-F5 (F0, F1, F2, F3, F4, F5) according to NF X 10-702 (smoke density test) and the NF X 70-100 (toxicity testing) together to assess the level F smoke toxicity
Wire and cable C1, C2 level test: NF C 32-070 C1, C2, NF C 32-070 C1-level cable test requirements stricter than the NF C 32-070 C2 Multi. C1 grade flame retardant cables used in place stringent requirements, testing is carried out using specialized equipment. Test when a 160CM cable hung vertically on the sample rack, the role of radiation under the ignition furnace test, tests 30MIN, 10MIN stop every ventilation 1MIN, test, cable intact chimneys above, the cable C1 level.
