Title (German)

Bahnanwendungen - Brandschutz in Schienenfahrzeugen - Teil 5: Brandschutzanforderungen an die elektrische Ausrüstung einschließlich der von Oberleitungsbussen, spurgeführten Bussen und Magnetschwebefahrzeugen; Deutsche Fassung EN 45545-5:2013+A1:2015

Overview

This European Standard DIN EN 45545-5:2013+A1:2015 "Railway applications - Fire protection on railroad vehicles - Part 5: Fire safety requirements for electrical equipment including that of trolley buses, track guided buses and magnetic levitation vehicles" has been developed from existing fire safety regulations for railway vehicles from the International Union of Railways (UIC) and different European countries. In using the operation and design categories defined in EN 45545-1, the requirements laid down in the different parts of EN 45545 will take into account the current operating conditions for European public rail transport. This document has been prepared by Technical Committee CEN/TC 256 "Railway applications", the secretariat of which is held by DIN (Germany). The responsible German committee is Working Committee NA 087-00-14 AA "Fire safety" of Standards Committee Railway (FSF) at DIN. This series of the European Standard "Railway applications - Fire protection on railway vehicles" consists of: - Part 1: General; - Part 2: Requirements for fire behavior of materials and components; - Part 3: Fire resistance requirements for fire barriers; - Part 5: Fire safety requirements for electrical equipment including that of trolley buses, track guided buses and magnetic levitation vehicles; - Part 6: Fire control and management systems; - Part 7: Fire safety requirements for flammable liquid and flammable gas installations. This Part (DIN EN 45545-5) specifies the fire safety requirements for electrical equipment on railway vehicles, including that of trolley buses, track guided buses and magnetic levitation vehicles. The measures and requirements, specified in this European Standard meet the objective of protecting passengers and staff in railway vehicles in the event of a fire on board by: - lowering the risk of starting a fire both during operation and as a result of technical defect and/or malfunction of the electrical equipment; - ensuring that electrical emergency equipment continues to be functional until evacuation is complete. This standard differs from DIN EN 45545-5 (VDE 0115-545):2013-07 as follows: a) EN 50547, Railway applications - Batteries for auxiliary power supply systems, has been included as a new reference (Clause 2); b) The heading and the text of Subclause 5.6 have been replaced by the following: 5.6 Batteries for auxiliary power supply systems and supply circuits Gases from batteries shall be vented to the exterior of the railway vehicle and shall not be vented into a passenger area or a staff area. Batteries for auxiliary power supply systems shall be in accordance with EN 50547. Cables between the battery and the battery protective devices shall be insulated against short circuits. Either one or both of the following shall be used: - supplementary insulation of the cable according to EN 61140; - internal insulation of the battery box with at least an electrolyte resistant insulation varnish. Where neither pole of a battery is bonded to the railway vehicle body, protective devices shall be fitted to both poles. If the battery layout needs interconnection cables between separate battery enclosures, only the external poles, not the interconnection cables, shall have protective devices against battery circuit overcurrent.
