Material Evaluation

The ProLine P51*00K ... and P52*00K ... transducers with their combustible
materials meet the material requirements for hazard level HL 3 according to
EN 45545-2 for installation on the outside of rolling stock. This includes
underfloor and roof containers, and engine rooms of locomotives and trac-
tion units. Inside rolling stock the transducers must be installed in closed
and fire-protected enclosures (see page 62 for details on installation).
The combustible materials are listed in the Flammable Materials List on
page 84. According to the Flammable Materials List, the fire protection for
printed circuit boards must be verified by material testing.
All other combustible materials are grouped.
For combustible materials or groups of combustible materials with a com-
bustible mass less than 10 g , the fire protection need not be verified.
Materials from section 4.7 of EN 45545-2:
• Electronic components on printed circuit boards
(digital and analog components)
The basic requirements of section 4.1 of EN 45545-2 are met.
