IS 1569-1976 Specification for capacitors used in circuits for tubular fluorescent lamps, high-pressure mercury lamps and low-pressure sodium vapor discharge lamps
1.1 This standard specifies the requirements for both self-healing and non-self-healing continuously rated ac 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 and at altitudes up to 3 000 m.
1.1.1 It covers capacitors intended for connection in shunt, series or an effective combination of these.
1.1.2 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.
1.2 The standard does not cover radio-interference suppressor capacitors.
