DIN EN 62718:2016-10

This standard has been prepared for the specifics of railroad applications to supplement the usual standards. It covers the general, safety-related and operational requirements in addition to, or instead of, the requirements contained in IEC 61347-1, IEC 61347-2-3, IEC 61347-2-4, IEC 61347-2-5, IEC 61347-2-6 and IEC 61347-2-7. This standard specifies the performance and constructional requirements, and associated tests, for d.c. supplied electronic ballasts used to supply fluorescent lamps for lighting on railway rolling stock. Its requirements replace those of IEC 61347 for all railway rolling stock applications and specify and complete those of IEC 61347 for the specific needs of railway rolling stock applications. This international standard applies to electronic ballasts - supplying pre-heated cathode fluorescent lamps without integrated starters, tubular or single capped, according to IEC 60081 and IEC 60901 respectively, - having a single and non-adjustable luminous flux level. The responsible committee is DKE/UK 351.1 "Fahrzeuge" ("Rolling stock") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
