Italy Standard UNFER prE10.02.977.3

UNFER prE10.02.977.3 Railway and Tramway Vehicles - Guidelines For Fire Protection Of Railway, Tramway And Guided Path Vehicles - Design Criteria - Measures For Fire Restraining - Signaling, Control And Evacuation Systems.

the prE10.02.977.3 Similar to the French Standard, the Italian Standard provides the classification of the material/item by "reaction to fire" and "smoke" (combination of smoke emission and toxicity).

UNFER prE10.02.977.3 Reaction to fire

For the parameter "reaction to fire" (FI parameters) are provided six categories: Class 0-Class 5Class 0、Class 1、 Class 2、 Class 3、Class 4、Class 5

Class 0 is evaluated by ISO 1182 "non combustibility test",
Class1 -Class 5 are determined by the combination the above parameters evaluated with two tests:
UNI 8456 --"reaction to fire by applying a small flame on both surfaces" and UNI 9174  "reaction to fire of material attacked by flame with radiant heating",
UNI 8457 --"reaction to fire of material attacked by flame on one surface" and UNI 9174

UNFER prE10.02.977.3 Smoke parameters

The "smoke" parameter is obtained identically to the French Standard, namely from combination of "smoke emission" and "toxicity index" (F value). The first one is evaluated by NF X 10-702 (Smoke density Chamber) and the second one with NF X 70-100 (toxicity test). There are three acceptable classes from F1 - F3(F1、F2、F3)。

For electrical materials smoke emission and smoke toxicity are separately evaluated with NF X 10-702 and IEC EN 50267 part 1 and 2.

The classification system is done by a "threshold value" for "reaction to fire" and "smoke" for each listed item described in two summary tables in the standard (one for electrical components the second for all other materials/item).
