Menzolit SMC and BMC for rail applications |
|
|
|
Rail applications usually require the stiffness and surface performance levels as other applications do. However beyond these well known properties of SMC and BMC a major demand for mass transit are the fire, smoke and toxicity advantages of materials used outside and especially inside the train.
Fire and smoke standards for rail / passenger – mass transit
There are still many national standards in place, the struggle for a European one is still not established as a common standard, only as Technical Specification.
France, AFNOR NF F 16-101
The AFNOR NF F 16-101 contains within others.:
_ NF X 70-100 ( Smoke toxicity )
_ NF X 10-702 ( Smoke density )
_ NF P 92-504 ( Spread of flame )
Italy, UNIFER E 10.02.977
The UNIFER E 10.02.977 contains f.e.:
_ UNI 9174
_ UNI 8456
_ AFNOR NF F 16-101
