DIN CLC/TR 50718:2025-12

This document guides users of the EN 45545 series, particularly EN 45545-2:2023, in the application of these standards in designing and assessing Ni-Cd batteries on board trains for their fire protection measures. This document excludes any new requirements, considering only the requirements stated by the above listed standards. However, since the EN 45545 series contain generic requirements and do not specifically refer to Ni-Cd batteries, this document helps the application for those batteries. In DIN EN 45545-2:2023-12 Ni-Cd batteries are treated as unlisted products. As a result, very different interpretations with regard to application of the DIN EN 45545 series of standards to Ni-Cd batteries on rolling stock are possible. Developers, experts, manufacturers, and customers have very different opinions which may involve problematic aspects, thus impeding specifications and agreements. This document is a report on current experience and best practices in the application of the DIN EN 45545 series of standards for Ni-Cd batteries in rolling stock.
