Railway applications - Fire protection on railway vehicles - Part 2: Requirements for fire behaviour of materials and components
This part of EN 45545 specifies the reaction to fire performance requirements for materials and products used on railway vehicles as defined in EN 45545-1.
The operation and design categories defined in EN 45545-1 are used to establish hazard levels that are used as the basis of a classification system.
For each hazard level, this part specifies the test methods, test conditions and reaction to fire performance requirements.
It is not within the scope of this European Standard to describe measures that ensure the preservation of the vehicles in the event of a fire.

Overview
EN 45545-2:2020/FprA1 - Railway applications - Fire protection on railway vehicles - Part 2: Requirements for fire behaviour of materials and components (CEN) defines the reaction-to-fire performance requirements for materials and products used on railway vehicles. Building on the classification framework in EN 45545-1, this part establishes hazard levels based on operation and design categories and prescribes the applicable test methods, test conditions and performance criteria for each hazard level. It addresses material behaviour in fire (flammability, heat release, smoke, toxic gases) but does not cover measures for preservation of the vehicle structure in a fire.
Key Topics
- Scope and classification
- Uses operation and design categories from EN 45545-1 to derive hazard levels and required performance.
- Reaction-to-fire performance
- Requirements focus on ignition, flame spread, heat release, smoke production and related reaction parameters.
- Specified test methods
- References internationally recognized tests (cone calorimeter, glow-wire, single-flame source, non-combustibility, smoke density, cable fire tests). The FprA1 amendment updates several normative references to current EN/ISO/IEC standards.
- Certification and compliance
- Defines how materials/components are assessed against hazard-level criteria - used for product approval and acceptance testing.
- Regulatory alignment
- Prepared under CEN mandate and aligned with EU requirements (e.g., TSI LOC&PAS reference to earlier EN 45545 versions). The amendment includes transitional provisions to manage changeover of certificates.
Applications
Who uses EN 45545-2 and why:
- Rolling stock designers and OEMs - select compliant materials and components during specification and design to meet fire-safety requirements.
- Materials and component manufacturers - develop and test products to demonstrate conformity with required hazard-level performance.
- Testing laboratories and certification bodies - perform mandated reaction-to-fire tests and issue conformity reports.
- Railway operators, procurers and maintenance teams - include EN 45545-2 criteria in procurement specifications and material replacement decisions.
- Regulatory and safety engineers - integrate test results into risk assessments, fire safety strategies and documentation.
Practical uses include material selection, supplier qualification, product type-approval, procurement clauses, and demonstrating compliance with European rail fire-safety rules.
