2Scope / Description
This International Standard specifies performance requirements for ballasts for discharge lamps such as high-pressure mercury vapour, low-pressure sodium vapour, high-pressure sodium vapour and metal halide lamps. Clauses 12 through 15 each detail specific requirements for a particular type of ballast. This standard covers inductive type ballasts for use on a.c. supplies up to 1 000 V at 50 Hz to 60 Hz associated with discharge lamps, having rated wattage, dimensions and characteristics as specified in the relevant IEC lamp standards.
NOTE 1 For certain types of discharge lamps an ignitor is required.
NOTE 2 Extension of the standard to cover ballasts incorporating, or for use with, series capacitors is under consideration.
NOTE 3 The performance requirements of ballasts for tubular fluorescent lamps are covered by IEC 60921.
NOTE 4 There are regional standards regarding the regulation of mains current harmonics for end-products such as luminaires and independent control gear. In a luminaire the control gear is dominant in this respect. Control gear, together with other components, should comply with these standards.
