IEC 62442-2:2022可通过以下方式获得:；IEC 62442-2:2022 RLV；其中包含国际标准及其红线版本，显示了与前一版本相比技术内容的所有变化。IEC 62442-2:2022规定了放电灯（不包括低压汞荧光灯）用电磁控制设备的功率损耗、总输入功率和电子控制设备的备用功率的测量方法。还定义了放电灯控制装置效率的计算方法。假设控制设备设计用于高达1000 V的直流电源和/或高达1000 V的交流电源，频率为50 Hz或60 Hz。第三版取消并取代2018年出版的第二版。本版为技术修订版。 与上一版相比，本版包括以下重大技术变更: -第2部分的标题已修改； -本版本与IEC 62442-1和IEC 62442-3一致； -增加了符合IEC 63103的非有功功耗测量方法的参考和使用。

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.
