BS EN 61000-4-14:1999+A2:2009 Electromagnetic compatibility (EMC) - Testing and measurement techniques - Voltage fluctuation immunity test for equipment with input current not exceeding 16 A per phase
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 connected to 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 a physiological 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 the
performance criteria, are indicated in the product, product family or generic standards as applicable. However, most product groups do not have a history of being susceptible to voltage fluctuations. Consequently, testing for these phenomena is often not required.
