Defines 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.

This International 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 IEC61347 for all railway rolling stock applications and specify and complete those of IEC61347 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 IEC60081 and IEC60901 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.
