Introduction Environmental conditions and general requirements for electronics for rolling stock are given by the following standards EN 50125-1 and EN 50155. This standard has been developed specifically for railway applications, to supplement the current standards. It covers general, safety and performance requirements in addition to or in place of those contained in EN 60925 and EN 60924. NOTE 1 When applied unchanged the clauses of EN 60924 are either referred in this standard or introduced into if they are short texts. NOTE 2 When a clause of EN 60924 applies with changes or is replaced by more specific requirements generally a short note explains the difference or the reason for that. NOTE 3 Annex H gives clause by clause correspondence between EN 60924 and this standard. NOTE 4 EN 60924 will be replaced by EN 61347-1, EN 61347-2-4, EN 61347-2-5, EN 61347-2-6 and EN 61347-2-7. 1 Scope 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. 2 Normative references This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate place in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 45545-5 1)
