Electromagnetic compatibility (EMC) - Testing and measurement techniques. Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests1 Scope and object This part of IEC 61000 defines the immunity test methods and range of recommended basic test levels for electrical and electronic equipment with rated current up to 16 A per phase at disturbance frequencies up to and including 2 kHz (for 50 Hz mains) and 2,4 kHz (for 60 Hz mains) for harmonics and interharmonics on low voltage power networks. It does not apply to electrical and electronic equipment connected to 16 2 3 Hz , or to 400

A rated current not exceeding 125 A
