FIRE TRIGLASS® profiles: certified according to EN 45545-2/2013 for the highest hazard level
TOP GLASS produces FIRE TRIGLASS® profiles with high fire resistance properties and very low smoke emission.
We have developed a special formulation for the railway industry using acrylic resin halogen free, modified with a specific know-how.
One of the most important item in the study of products in this field is infact the fire protection on vehicles and the analysis of the fire reaction/resistance properties of the materials.
The FIRE TRIGLASS® profiles can be used in different applications and not only in the railway one: cable trailers in internal environments, tunnel and industrial elements.
THE CERTIFICATION EN 45545-2/2013
The FIRE TRIGLASS® material was certified according to EN 45545-2/2013 and it complied with the requirements for the highest hazard level “HL3” for “R1”.
In the last years an harmonized testing methods and classification criteria were developed to facilitate the European interoperability of railway rolling stock. In 2013 CEN 256 WG1 and TC9X WG3 published the standard EN 45545: “Fire Protection on Railway Vehicles”, that from 2016 substituted the national code.
The hazard level required for each material is evaluated with respect to four design categories and four operation categories; the highest safety level is named “HL3”.
|Design categories/Operation categories||Standard vehicles||Vehicles part of an automatic train||Double decked vehicle||Sleeping and couchette vehicles|
|Vehicles may be stopped with minimum delay. Safe area always present||HL1||HL1||HL1||HL2|
|Tunnels or elevated structures. Side evacuation available and rescue stations reachable in a short running time||HL2||HL2||HL2||HL2|
|Tunnels or elevated structures. Side evacuation available and rescue stations reachable in a long running time||HL2||HL2||HL2||HL3|
|Tunnels or elevated structures without side evacuation available. Side evacuation available and rescue stations reachable in a short running time.||HL3||HL3||HL3||HL3|
Moreover, the products are classified according to their final applications; for each group a specific performance requirement level (from R1 to R26) is defined. TOP GLASS Industries profiles are classified as “R1”, due to their application also in the internal environments.
The evaluation of the Top Glass profiles fire reaction properties includes different parameters:
- Maximum Average Rate of Heat Emission (MARHE)
- Flame spread
- Smoke density: qualitative and quantitative analysis of the gases emitted
The values for the highest hazard level (“HL3” – “R1”) are reported in the following table.
|Test required||EN ISO 5659-2||EN ISO5658-2||EN ISO5659-2||EN ISO5660-O|
|Parameter||Ds (4)||VOF4||CFE [kW/m2]||CITG||Marche [kW/m2]|
