Fire protection in railway vehicles 02 November 2021

Passenger safety plays a central role in rail transport, which naturally includes fire protection. The fire behaviour of materials used must be intensively tested and classified. This also applies to the adhesives and sealants used, which is why Kisling AG’s new ergo range of structural adhesives has been tested according to EN 45545-2.

Kisling’s ergo 1675, ergo 7430 and ergo 7440 structural adhesives have been tested and certified for smoke toxicity (ISO 5659-2), heat generation (ISO 5660-1) and flame propagation (ISO 5658-2). They also meet the requirement sets R1, R7 and R17 of EN 45545-2 with the best grade HL1-3 (hazard level 1 – 3).

The two component epoxy resins, ergo 7430 and ergo 7440, as well as the methacrylate adhesives – ergo 1675, also make a significant contribution in terms of process simplification, acceleration and safety.

Toxic gases and smoke can develop in the event of fire, particularly when plastics and adhesives are involved. Flammability and continued burning behaviour are also important technical properties to take into account when selecting these materials. The second part of the DIN EN 45545 ‘fire protection in railway vehicles’ standard regulates the requirements for fire behaviour of materials and components. This gives processors a guideline as to which adhesives are suitable for which applications and their respective fire protection requirements.
