Railway
TROCELLEN CLASS TRAIN is the certified product line for railway industry. It is realized in close cell, chemically cross-linked polyethylene foam, laminated, from one side, with an aluminium sheet. The product is available in adhesive rolls, thicknesses from 3 to 40 mm.
TROCELLEN CLASS TRAIN is certified R1 HL3, according to the norm EN 45545-2 “Fire protection on railway vehicles. Part 2: Requirements for fire behavior of materials and components”. EN 45545 norms indicate requirements of materials and components to be installed in railway vehicles with the aim of guaranteeing the protection of passengers and staff, in the event of a fire on board. The above mentioned norms introduce the concept of hazard level of a vehicle (HL1, HL2 and HL3, depending on increasing hazard), as a combination of two elements: the operational category (OC) and the design category, that is related to the type of rolling stock.
HAZARD LEVEL
| DESIGN CATEGORIES | ||||
|---|---|---|---|---|
| OPERATION CATEGORIES (OC) | N Standard vehicles |
A Vehicles forming part of an automatic train having no emergency trained staff on board |
D Double decked vehicle |
S Sleeping and couchette vehicles |
| OC 1 Vehicles for operation on infrastructure where railway vehicles may be stopped with minimum delay, and where a safe area can always be reached immediately |
HL1 | HL1 | HL1 | HL2 |
| OC 2 Vehicles for operation on underground sections, tunnels and/or elevated structures, with side evacuation available and where there are stations that offer a place of safety to passengers, reachable within a short running time |
HL2 | HL2 | HL2 | HL2 |
| OC 3 Vehicles for operation on underground sections, tunnels and/or elevated structures, with side evacuation available and where there are stations that offer a place of safety to passengers, reachable within a long running time |
HL2 | HL2 | HL2 | HL3 |
| OC 4 Vehicles for operation on underground sections, tunnels and/or elevated structures, without side evacuation available and where there are stations that offer a place of safety to passengers, reachable within a short running time |
HL3 | HL3 | HL3 | HL3 |
Depending on the type of product to install and its position within the rail vehicle, the EN 45545-2 norm indicates 26 requirements to be fulfilled: R1 is the specific requirement for insulation materials.
The tests to be performed, the parameters to be evaluated and the values to be met are set for each requirement, according to the corresponding hazard levels (from HL1 to HL3).
MATERIAL REQUIREMENT SET FOR R1
| R1: | Test method reference | Parameter and unit | Maximum or minimum | HL1 | HL2 | HL3 |
|---|---|---|---|---|---|---|
| IN11 – Interior vertical surfaces (walls, partitions, doors, windows, insulation materials, kitchen interior surfaces…) IN1B – Interior horizontal downward-facing surfaces (ceiling paneling, insulation materials…) IN1D – Interior surfaces within cavities (horizontal or vertical) IN1E – External surfaces of enclosures containing technical equipment (inside the body shell) IN4 – Luggage storage areas IN5 – Driver’s desk (paneling and surfaces of the driver’s desk) IN6A – Interior surfaces of gangways (interior side of gangway membrane, interior lining of the gangway) IN7 – Window frames (including sealants and gaskets) IN8 – Curtains and sunblind in passenger area and staff area, staff compartments IN9B – Tables, folding tables downward facing surface IN11 – Litter bins and ashtrays IN12A – Air ducts – Interior surfaces IN12B – Air ducts – Exterior surfaces IN14 – Devices for passenger information (information display screens in passenger areas) F5 – Underside surface of couchettes and beds |

CHARACTERISTICS
TROCELLEN CLASS TRAIN represents the ideal solution for the thermal insulation of railway vehicles.
Characteristics and advantages:
- made of long lasting closed cell polyethylene insulation foam;
- very good reaction to fire;
- classified R1 HL3 according to EN 45545-2, the maximum level
- suitable to be installed in any rolling stock category, even in sleeping and couchette vehicles;
- good thermal conductivity (λ at 0 C°: 0,038 W/mK);
- constant insulation value*;
- closed cells, to inhibit water absorption;
- clean, non toxic, mould and bacteria resistant, odorless;
- flexible enough to follow tight angles and strong enough to withstand rough handling;
- economically convenient.
*TROCELLEN products tested after 23 years of usage has the same insulating value. Test reports available on request.
