This part of IEC 61000 is a basic electromagnetic compatibility (EMC) publication. It considers immunity tests for electrical and/or electronic equipment in their electromagnetic environment.Only conducted phenomena are considered, including immunity tests for equipment connectedto public and industrial power supply networks.This part aims to establish a reference for evaluating the immunity of electric and electronic equipment when subjected to positive and negative low amplitude voltage fluctuations.The voltage fluctuations considered by this standard do not include flicker, which is aphysiological phenomenon due to lighting luminance fluctuations.This standard applies to electrical and/or electronic equipment that have a rated input current up to 16 A per phase. It does not apply to electrical and/or electronic equipment connected to d.c. or a.c. 400 Hz distribution networks. Tests concerning these networks will be covered by other IEC standards.The immunity test levels required for a specific electromagnetic environment, together with theperformance criteria, are indicated in the product, product family or generic standards asapplicable. However, most product groups do not have a history of being susceptible to voltagefluctuations. Consequently, testing for these phenomena is often not required.
