We conduct the following inspections at our testing facility, which has been accredited by the Federal Railway Administrative Office (EBA):

Testing in accordance with DIN 5510-2, classes S1-S5; SR1-SR2; ST1-ST2
This standard applies to rail vehicles within the purview of the German Railway Construction and Operating Ordinance (EBO), the Construction and Operating Ordinance for Narrow-Gauge Railways (ESBO), the Magnetic Levitation Train Construction and Operating Ordinance (MbBO) and the Construction and Operating Ordinance for Streetcars (BOStrab). The purpose of the standard is to establish classifications for fire behaviour and the side-effects of combustion for materials and components used in building the vehicles. Also to be specified are the testing procedures required for this purpose, requirements as to fire behaviour and combustion side effects, and requirements associated with fire prevention.
The objective of testing as per DIN 5510-2:2009-05, in conjunction with DIN 53438 (S1) and DIN 54837, is to determine the fire behaviour of materials used in rail vehicles when exposed to the flame of a gas burner. The findings are used for classification as per flammability, smoke generation and drip properties.
The test procedure is described in DIN 53438 and/or DIN 54837 while DIN 5510-2 details the requirements, test procedures and classifications.

• Testing to determine the flammability class (S1) is conducted as per the DIN 53438-1 to DIN 53438-3 standards. At least 5 small parts are used as specimens (see DIN 5510-2, Paragraph 5.3 b); alternately, specimens as per DIN 53438-1 to DIN 53438-3 may be used. The parts are mounted in their installed orientation while being exposed to the flame wherein the most critical exposure configuration for the installed small component will be selected. The flame will be directed at the surface, in so far as the edges are not covered. If the edges are exposed, then the flame will be directed at these edges. The test is deemed to have been passed if the flames supported by the small component do not exceed a height of 15 cm, measured from the point at which the burner’s flame impinges upon the part to the tip of the flame.
• As regards flammability classes S2 to S5, testing is described in DIN 54837. Here again at least 5 specimens measuring 190 mm x 500 mm x product thickness will be required. Components such as head restraints, fold-away tables, arm rests, covers that (due to their shape or dimensions) do not permit removal of test specimens 190 mm x 500 mm in size are to be carried out either at original size or using a section of the component of a suitable shape. If it is not possible to assess the flammability for such parts at all, then the inspection can be made on flat models measuring 190 mm x 500 mm. Sections 500 mm long are to be used when testing profiled components such as window and door gaskets, braces, hoses, cover strips, tubing and the like. (Alternately, sections as per Table 5 in DIN 5510-2 may be used.)

Examination of railway seats as per DIN 5510 - 2 and the technical guidelines issued by the Deutsche Bahn AG and UIC 564-2
Proof of suitability for use in regard to fire protection is generally to be demonstrated by way of tests carried out on original-equipment seats with the backrest and all the original-equipment components installed. The purpose of testing as per DIN 5510-2 is to determine the ignition and burning properties of seats and bench-type seats in rail vehicles when exposed to a burning paper cushion.
The following requirements are to be satisfied during testing as per Section 4.2.5.3 in order to demonstrate suitability: the height of the flame, above the highest point on the seat surface, may not exceed 100 cm. In none of the seats may the leading edge of the flames reach the side edges of the seat. The flames shall have gone out after the 15th minute of testing, at the latest. To satisfy fire protection steps 2 to 4, no individual value in total smoke production (TSP) may exceed a value of 60 m². Supplementary requirements will be found in the current version of the standard.

Testing smoke toxicity in the testing chamber as per DIN EN ISO 5659-2 (DIN 5510-2:2009-05)
Additional requirements in the DIN 5510-2 standard
Smoke toxicity is tested for vehicles in fire protection steps 2 to 4 in accordance with Annexes C and D of DIN 5510-2 (May 2009). Three test specimens measuring 75 mm square are used. The test specimens are to correspond to the final application. The thickness of the test specimens may, however, not exceed 25 mm. Thicker items are to be reduced, on the surface not to be exposed to the flame during testing, to an overall thickness of 25 mm. The test specimens, in a horizontal orientation, are to be subjected to thermal radiation at a level of 25 kW/m². The smoke released will be collected and toxicity analysis will follow twice, i.e. after 4 and 8 minutes of exposure.
Smoke toxicity is then evaluated on the basis of the fractional effective dose (FED). Used as the basis here is a reference volume of 150 m³ for the vehicle.
Vehicle components satisfy the requirements of the various fire protection states if FED(tpermissible) is equal to or less than 1.
