The EN 50264-2-1:2008 standard provides comprehensive guidelines for the specification of single core cables utilized in railway applications, specifically focusing on those designed for power and control with enhanced fire performance characteristics. This standard outlines critical aspects such as cable construction, dimensions, and performance requirements for various voltage ratings, including 0.6/1 kV and 1.8/3 kV configurations. One of the key strengths of EN 50264-2-1 is its emphasis on safety under fire conditions. The requirement for cables to exhibit limited flame propagation and reduced emission of smoke and toxic gases is particularly pertinent in the railway industry, where the safety of passengers and crew is paramount. This focus ensures that the cables not only function reliably under normal operating conditions, with a continuous conductor temperature not exceeding 90 °C, but also perform adequately in emergency situations. Additionally, the standard specifies tinned copper conductors classified under EN 60228, which enhances conductivity and resistance to corrosion. The halogen-free insulation and sheath materials are another significant strength, aligning with modern environmental standards by minimizing the release of harmful substances in the event of a fire. The standard's comprehensive coverage of cable types (including unscreened and sheathed options) and cross-sectional areas ranging from 1 mm² to 400 mm² also makes it highly relevant for a variety of railway applications. This ensures versatility while maintaining strict compliance with safety and performance specifications. Moreover, EN 50264-2-1 is crucially articulated as a supplementary document to Part 1 “General requirements,” ensuring that users have access to a cohesive framework that encompasses both general and specific requirements for railway rolling stock cables. This holistic approach not only simplifies the implementation of the standard but also enhances its usability and applicability in real-world scenarios.
