Specifies essential safety and associated testing requirements which must be met before electronic ballasts may be offered for sale. It is intended to be read in conjunction with AS 3100 and is based on IEC 928.

This Specification prescribes safety requirements for electronic ballasts designed for use on a.c. supplies up to 1000 V at 50 Hz, associated with tubular fluorescent lamps having rated wattages, dimensions and characteristics as specified in either AS 1201, IEC 901, or by the ballast manufacturer and operated with or without a starter switch.This specification does not apply to the following:(a) Ballasts of the reactive type, requirements for which are specified in AS 3168.(b) Ballasts designed for use with cold-cathode fluorescent lamps, requirements for which are specified in AS 3143.(c) Capacitors which are incorporated in starters. (d) Ballasts of the resistive type.NOTE: It is emphasized that only safety matters and closely allied conditions are specified herein. Attention is drawn to AS 3963 which contains requirements intended to ensure the satisfactory performance of electronic ballasts in fluorescent lamp circuits.
