7.3 Material Evaluation
The P45000 transducers with their combustible materials meet the material requirements according to
EN 45545-2 when installed on the exterior of rail vehicles. These include underfloor and roof contain-
ers. In the interior of rail vehicles, the transducers must be mounted in closed and fireproof control
cabinets.
The combustible materials are shown in the following list. Listed components were evaluated accord-
ing to their fire characteristics and fulfill hazard level HL 3. Components not included on the list were
evaluated and grouped according to Grouping Rule 1.
The components on the PCB required for the function meet the primary requirements from section 4.1
of EN 45545-2 (see section 4.7).
