IEC 62442-2:2022 defines a measurement method of the power losses of electromagnetic controlgear, the total input power and the standby power of electronic controlgear for discharge lamps (excluding low-pressure mercury fluorescent lamps). A calculation method of the efficiency of controlgear for discharge lamp(s) is also defined. It is assumed that the controlgear are designed for use on DC supplies up to 1 000 V and/or AC supplies up to 1 000 V at 50 Hz or 60 Hz. This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the title of Part 2 has been modified;
- this edition has been harmonized with IEC 62442-1 and IEC 62442-3;
- the reference to and use of the measurement methods for non-active power consumption in accordance with IEC 63103 have been added.
