This International Standard states the requirements for both 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 µF, having a rated voltage not exceeding 1 000 V, which are intended for use in discharge lamp circuits* operating at 50 Hz or 60 Hz and at altitudes up to 3 000 m.It covers 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, plastic film or a combination of both, either metallized or with metal foil electrodes.This standard does not cover radio-interference suppressor capacitors the requirements for which are found in IEC 60384-14.Tests in this standard are type tests. Guidance on conformity of production is given in annex A.
