- 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 EN 60925 for all railway rolling stock applications and precise and complete those of EN 60924 for the specific needs of railway rolling stock applications. This standard applies to electronic ballasts - supplying pre-heated cathode fluorescent lamps without integrated starters, tubular or single capped, according to EN 60081 and EN 60901 respectively, - having a single and non adjustable luminous flux level. It does not apply to electronic ballasts supplying non pre-heated cathode lamps and/or lamps with integrated starters.
