France
The classification grades of the French standard for the combustion behavior of materials and their components are quoted as follows:
NF F 16-101: " All Vehicles - Burning behavior - Material Selection ";
NF F 16-102: " All Vehicles - Combustion behavior - Material selection - Application on electrical equipment" .
Combustion reaction test
For large sample materials, the combustion reaction test classifies the material/product into 6 categories: from M0 to M5 according to the obtained parameters, which are derived from the building standard.
Parameters of smoke
The parameters of smoke in the standard are evaluated by the emission of smoke and the toxicity index.
According to NF 16-101, these two parameters are given “ Smoke value ” It is classified from F0 to F5.
Germany
The German standard for test procedures and classification of combustion behavior and combustion effluents is defined in accordance with DIN 5510 Part 2.
The following parameters are used to describe the classification of combustion behavior of materials and their components, including materials used in the exterior and interior of the vehicle body:
Flammability
Smoke development
Drop
The test sample must meet the final requirements for use. (DIN 5510-2)
United Kingdom
According to BS6853“ Standard for fire protection requirements for the design and construction of passenger trains The British classification level.
This classification level is divided into the following three categories according to traffic conditions:
Class Ia and Ib (Metro),
Class II (above ground).
The parameters of the British standard combustion behavior are evaluated by the following aspects:
Flammability,
Spread of flame,
Heat release (using BS476 Part 6),
Opacity of smoke,
Toxicity of smoke.
Italy
The Italian standard is classified according to the combustion behaviour of the materials and their components used in accordance with the standard UNIFER PrE10.02.977.3 (which specifies the fire protection requirements for railways, tram tracks and other traffic tracks and evaluates the combustion behaviour of some materials in part III - limit values).
Similar to the French standard, the Italian standard is based on the material. Combustion reaction ” And “ Smoke ” It was graded (including smoke and toxicity).
United States
The vast majority of fire safety requirements for passenger trains in the United States consist of material burn test standards designed to prevent fire or delay the development and spread of fire, and material burn performance is evaluated according to different test methods. The FRA test and other similar requirements for materials for railway applications provide a set of design specifications for material selection.
European Union
In 1997, the European Union established a 3-year research programme to complete a 7-part European standard (fire protection of railway locomotives) prEN 45545, to assist CEN/TC256/WG1 and CENELEC/TC9X/WG3 in drafting Part 2 (Requirements for the combustion behaviour of materials and their components).
