Application Summary AI generated
This standard specifies the immunity test method for electrical and electronic equipment when subjected to variations in the power frequency (typically 50 Hz or 60 Hz). It is applied in EMC testing to verify that equipment, such as household appliances, industrial machinery, and telecommunications devices, can function correctly during temporary frequency fluctuations in the AC mains supply. The test is relevant for manufacturers and testing laboratories assessing product reliability in real-world power grid conditions.
