Reminder of EN45545 – Fire protection standards

Samaro and its partners develop solutions that meet the requirements of the EN 45545 standard for passenger safety in rail transport.

The EN45545 standard is developed to facilitate the interoperability of trains across Europe, it was decided to harmonise the different train management systems including fire and smoke standards. It replaces all the old standards of the different European countries.

Our partners have built an industrial policy around these values and support us with our customers in this process.

Examples of requirements by application :

  • R1: for horizontal/vertical interior surfaces (ceiling, walls, window frames and display screens)
  • R22/23: for inner seals, coils, inductors and contacts
  • R24/25: for boards and printed circuits
  • R26: for small electronic products

How to select the right adhesive/potting dedicated to railway application:

  1. Determine the requirements applicable to the product in question (R1-R26)
  2. Determine the level of fire risk (hazard level HL1, HL2 or HL3)
  3. Identify a suitable material approved EN45545 (with the right requirement and hazard level)  that meets technical requirements
