IS 15885 : PART 2 : SEC 8 : 2011 : Safety Of Lamp Controlgear Part-2 Particular Requrements Section 8 Ballasts For Fluorescent Lamps

Reaffirmed 2016

1 SCOPE

This standard (Part 2/Sec 8) specifies safety requirements for ballasts, excluding resistance types, for use on ac supplies up to 1 000 V at 50 Hz, associated with fluorescent lamps with or without pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IS 2418 (Part 1) : 1977 ‘Tubular fluorescent lamps for general lighting service : Part 1 Requirements and tests (first revision)’ and IS 15687 ‘Single-capped fluorescent lamps’.

This standard applies to complete ballasts and their component parts such as reactors, transformers and capacitors. Particular requirements for thermally protected ballasts are given in Annex B.

Ballasts for conventional operation of lamps at mains frequency are covered, while ac supplied electronic ballasts for high frequency operation are excluded. These are specified in IS 15885 (Part 2/Sec 3) : 2011 ‘Safety of controlgear : Part 2 Particular requirements, Section 3 ac supplied electronic ballasts for fluorescent lamps’.

Capacitors having a capacitance greater than 0.1 µF are covered by IS 1569 : 1976 ‘Capacitors for use in tubular fluorescent lamps, high pressure mercury vapour lamps and low pressure sodium vapour discharge lamp circuits’. Capacitors having a capacitance less than or equal to 0.1 µF are specified in IS QC 302400 : 1994.

Performance requirements are covered in IS 1534 (Part 1) : 1977 ‘Ballasts for fluorescent lamps: Part 1 For switch start circuits (second revision)’.
