EN 45545 Compliant materials for the rail sector

As well as meeting the needs of the engineering industry in terms of performance and longevity, safety compliance is essential when choosing specialist insulation materials for the rail industry. Our entire range of rail materials are tested to industry requirements for fire, smoke and toxic fumes (FST). These tests are intended to increase safety in the event of a fire on-board. All rail insulation materials must be EN 45545 compliant, meeting the European standard for fire protection on railway vehicles. 3M provide indicative FST test data for our range of rail materials. Please note that this is for information only; further testing in the end use condition must be conducted in order to demonstrate performance against the standard(s) or compliance to regulatory requirements.

To comply with EN 45545, materials must behave in a certain way when exposed to fire:

Flame retardant: EN 45545 compliant materials must be flame retardant so that in the case of a fire, insulation materials successfully help to prevent the fire from spreading, providing more time for rail carriages to be safely evacuated.

Low smoke: EN 45545 compliant rail materials must also feature low smoke emissions in order to help prevent the penetration of smoke. Making sure that smoke density is as low as possible is vital for allowing train staff and passengers to escape the carriage and be rescued as quickly as possible without the dangers of smoke inhalation.

Low toxicity: Many standard insulation materials can create extremely hazardous toxic gas.
