IEC 62442-2:20 22作为IEC 62442-2:20 22 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62442-2:20 22定义了放电灯（不包括低压汞荧光灯）电磁控制装置功率损耗、总输入功率和电子控制装置待机功率的测量方法。还定义了放电灯控制装置效率的计算方法。假设控制装置设计用于50 Hz或60 Hz下高达1 000 V的DC电源和/或高达1 000 V的交流电源。这第三版取消并取代了2018年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-修改了第2部分的标题； -此版本已与IEC 62442-1和IEC 62442--3协调； -增加了对根据IEC 63103的非有功功耗测量方法的引用和使用。

IEC 62442-2:2022 is available as IEC 62442-2:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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.
