scope:

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 µ F, having a rated voltage not exceeding 1000 V, which are intended for use in discharge lamp circuits operating at 50 Hz or 60 Hz and at altitudes up to 3000 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 384-14. Tests in this standard are type tests. Guidance on conformity of production is given in annex A.
