Specifies requirements for self-healing and non-self-healing capacitors rated greater than 0.1 µF, and intended for use in tubular fluorescent, high-pressure mercury and low-pressure sodium vapour discharge lamp circuits. Based on IEC 566.

This Standard specifies requirements for self-healing and non-self-healing continuously rated a.c. capacitors, of up to and including 2.5 kvar and not less than 0.1 mF and having a rated voltage not exceeding 1000 V, which are intended for use in discharge lamp circuits operating at 50 Hz a.c. at altitudes up to 3000 m.This Standard applies to capacitors intended for connection in shunt or in series with the lamp circuit or an effective combination of these. It covers only impregnated or unimpregnated capacitors having a dielectric of paper, plastics film, or a combination of both, either metallized or with metal foil electrodes.This Standard applies, in particular, to capacitors for use in those discharge lamp circuits or ballasts to which the relevant Australian Standard or Approval and Test Specification refers to reference hereto.This Standard does not apply to radio-interference suppressor capacitors, the requirements for which are given in AS 3145.NOTES:1. Requirements for capacitors having a capacitance not greater than 0.1 mF, for use with fluorescent lamp ballasts, are given in AS 3168.2. Discharge lamp circuits within the scope of this Standard are as follows:(a) Tubular fluorescent.(b) High-pressure mercury vapour.(c) Low-pressure sodium vapour.(d) High-pressure sodium vapour.(e) Metal halide.
