This document guides users of the EN 45545 series, particularly EN 45545‑2:2020+A1:2023, 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.
