What is EN 45545-2:2019?

The EN45545-2:2019 is a European standard that specifies requirements for fire behavior of materials and components used in railway vehicles. It was introduced as a response to the need for improved safety measures in the railway industry, aiming to enhance the level of passenger protection in case of fire incidents. This article will explore the key aspects of EN45545-2:2019 and its significance in ensuring fire safety in railway vehicles.

Fire Performance Requirements

EN45545-2:2019 outlines stringent fire performance requirements for both materials and components used in railway vehicles. These requirements include parameters such as flame spread, smoke and toxic gas emission, heat release, and burning behavior. The goal is to limit the spread of fire, minimize smoke production, and reduce toxicity levels to provide passengers with sufficient time for evacuation in the event of a fire emergency.

Test Methods and Ratings

The standard defines specific test methods to evaluate the fire performance of materials and components. These tests measure various properties such as ignitability, flammable gases released during combustion, smoke density, toxicity, and heat release rate. The results obtained from these tests are then compared against defined performance criteria to determine the classification and rating of the tested materials or components.

Implementation and Compliance

EN45545-2:2019 is a legal requirement in the European Union for all new railway vehicles and retrofitting of existing ones. It sets the minimum safety standards that must be met by manufacturers and suppliers in order to ensure compliance. The standard applies to interiors, exteriors, and underfloor areas of railway vehicles and covers a wide range of materials and components including seats, flooring, walls, cables, and insulation. Adherence to the requirements of EN45545-2:2019 is essential for guaranteeing the safety of railway passengers and reducing the potential dangers associated with fire incidents.
