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 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. NOTE These lamps and associated ballasts are covered by IEC 60081, IEC 60901, IEC 60188, IEC 60192, IEC 60662, and IEC 61167 and by IEC 61347-2-8 and IEC 61347-2-9, respectively. 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 given in this standard are type tests. Requirements for testing individual capacitors during production are not included. Particular requirements for built-in capacitors having an insulation equivalent to double or reinforced insulation are given in Annex E.
