In August 2016 Thermamax insulation product were tested and certified in accordance with the requirements of EU-Norm 45545 in an accredited testing laboratory.

Every day millions of people worldwide use trains, trams, streetcars and other rail-based transport systems. The most important factor in the build and operation of rail vehicles is safety under all possible conditions, as even the smallest fire caused by defective components or negligent arson attacks could be catastrophic. Vehicle builder and operator alike place the highest priority on ensuring that all materials and components used in rail vehicle manufacture meet the most stringent safety requirements. These are controlled in the standard EN 45545, which was introduced in 2013 and since March 2016 replaced all previously valid national rules covering Fire Protection in Rail Vehicles. These new rules are not just concerned with safety but cover approval also. 

In addition Thermamax, with their high-temperature insulation systems for engine and exhaust gas aftertreatment installations in rail vehicles, have to take note of the special requirements for fire protection. For this reason in August 2016 the Mannheim-based company had a special textile-based insulation system, (outer shell/insulation/inner shell), tested at an approved testing institute. The product features specially layered technical fabrics combined with a silicate-fibre needle matting as carrier. Due to its high-temperature resistance – up to 650° C - and the excellent insulation effectiveness, this insulation system can cover the majority of rail vehicle applications including turbochargers, exhaust elbows, complete exhaust lines, as well as retrofitted exhaust gas aftertreatment.

The technical classification results from the fire-protection related testing confirms that the Thermamax insulation meets the demands of EN 45545-2 in respect of R7 requirements and Hazard Levels HL1, HL2, and HL3.

This means that the customer can choose an insulation system that is already classified and can be used for rail vehicle applications with the above requirement profile. Fitting the insulation to the particular geometry of the component to be insulated is all that is required, meaning no additional costs and time delays for material classification.
