EN 45545-2 Fire Protection Standard for Railway Applications
EN 45545-2 is the European standard that sets fire protection requirements for materials and components used in railway vehicles. This regulation plays a vital role in ensuring passenger safety by minimizing fire risks and controlling the spread of flames, smoke, and toxic gases in the event of a fire on board a train.
🚆 What is EN 45545-2?
EN 45545-2, part of the broader EN 45545 series, specifically focuses on the fire behavior of materials and products used in railway applications. It defines the required levels of fire resistance for materials installed inside and outside of rolling stock, depending on their location, function, and vehicle design category (e.g., high-speed trains, metro, trams). The standard replaces previous national standards like BS 6853 and DIN 5510-2, harmonizing fire safety criteria across the European railway industry. It is a key requirement for manufacturers and suppliers of railway components such as rubber seals, gaskets, insulators, flooring, and interior parts.🔥 Risk Categories & Hazard Levels
EN 45545-2 classifies train operating environments into three main risk levels (HL1, HL2, HL3), with HL3 being the most demanding. Product materials are tested against several criteria:- Oxygen Index (OI) – How easily the material ignites
- Smoke Density (Ds) – Visibility obstruction during fire
- Toxic Gas Emissions (CIT) – Concentration of harmful gases
- Heat Release Rate (HRR) – Energy released during combustion
🛠️ EN 45545-2 Compliant Rubber Components
At Babacan Rubber, we manufacture rubber components engineered to comply with EN 45545-2 standards. Our flame-retardant rubber formulations are suitable for various railway applications, including:- Door seals and window gaskets
- Cable protection sleeves
- Floor matting and insulation panels
- Anti-vibration mounts and bushings
- HVAC seals and duct covers
✅ Why EN 45545-2 Certification Matters
Complying with EN 45545-2 is not only a legal obligation for railway suppliers in Europe but also a guarantee of passenger safety and product reliability. Using certified rubber parts reduces fire hazards and improves the overall risk profile of your rolling stock fleet. Moreover, many OEMs and transit authorities now require EN 45545-2 certification as part of their procurement process, making compliance a competitive advantage in the rail industry.🌍 Global Supply, Local Standards

Frequently Asked Questions (FAQ) – EN 45545-2
EN 45545-2 is a European fire safety standard for railway vehicles. It defines the required fire resistance of materials and products to minimize fire hazards in trains. Compliance ensures improved passenger safety and meets legal requirements for railway manufacturers operating in Europe.
The standard classifies materials into three hazard levels: HL1 (low), HL2 (medium), and HL3 (high). These levels depend on the train type, operational environment, and the function of the component. HL3 is required for high-risk applications like underground trains and sleeping cars.
Materials are tested for flame spread, smoke density, heat release, and toxicity using ISO test methods such as ISO 5659-2, ISO 5660, and ISO 4589. Products must meet specified thresholds in these tests to achieve HL1, HL2, or HL3 certification.
Yes. Our railway rubber components are manufactured using flame-retardant compounds that meet EN 45545-2 requirements. We provide compliant products for HL2 and HL3 applications, tested under accredited laboratory conditions.
While EN 45545-2 is mandatory in the EU, many global railway projects—especially international contracts—adopt this standard for safety assurance. Using certified parts improves credibility, safety compliance, and chances of contract approval.
