RTS PRIORITY AREAS

Capability Statement

Combustibility, smoke density, smoke toxicity, etc. We can assist you with the questions and issues you have in relation to preventive material and design-based fire safety for rail vehicles by offering the following services. Our tests and test quantities: Combustible materials laboratory tests: Fire safety assessments must be produced for the materials used in rail vehicles. We can offer these tests in line with the following standards. DIN 5510-2: This standard describes the relevant fire-resistant material requirements with respect to combustibility, smoke density and toxicity based on the following standards: Determination of fire behaviour in accordance with DIN 54837 in a combustion shaft (combustibility class S, smoke propagation class SR, drop-forming class ST) – Determination of fire behaviour in accordance with DIN 53438 in a small combustion box (fire behaviour for surface ignition F and edge ignition K) – Determination of smoke toxicity in accordance with DIN EN ISO 5659-2 in the NBS Smoke Density Chamber with FTIR (FED values) EN 45545-2: This standard also describes the relevant fire-resistant material requirements with respect to combustibility, smoke density and toxicity with reference to the following standards: – Determination of the heat release rate (MARHE value) in accordance with ISO 5660-1 in the cone calorimeter – Determination of smoke toxicity and smoke propagation in accordance with DIN EN ISO 5659-2 in the NBS Smoke Density Chamber with FTIR (CIT, DS, VOF values) – Determination of floor combustibility (CHF criterion) in accordance with DIN EN ISO 9239-1 in the floor radiant panel – Determination of lateral flame spread (CFE criterion) in accordance with ISO 5658-2 in the spread-of-flame apparatus – Determination of fire behaviour for direct exposure to flames in accordance with DIN EN ISO 11925-2 Fire cause analysis tests: We conduct fire cause analysis tests on vehicles and vehicle assemblies that have been in a fire. This includes the following steps (also optional): – Inspection of the vehicle to record and document the damage – Further analyses in the laboratory – Fire cause analysis – Drafting of technical and/or organisational fire protection measures – Drafting of reports. DB Systemtechnik is QMS certified to the ISO 9001 standard.
