Electromagnetic compatibility (EMC) - Part 4-11: Testing and measurement techniques - Voltage dips, short interruptions and voltage variations immunity tests for equipment with input current up to 16 A per phase

This part of IEC 61000 defines the immunity test methods and range of preferred test levels*for electrical and electronic equipment connected to low-voltage power supply networks for*voltage dips, short interruptions, and voltage variations.*This document applies to electrical and electronic equipment having a rated input current not*exceeding 16 A per phase, for connection to 50 Hz or 60 Hz AC networks.*It does not apply to electrical and electronic equipment for connection to 400 Hz AC networks.*Tests for these networks will be covered by future IEC documents.*The object of this document is to establish a common reference for evaluating the immunity of*electrical and electronic equipment when subjected to voltage dips, short interruptions and*voltage variations.*NOTE 1 – Voltage fluctuation immunity tests are covered by IEC 61000-4-14.*The test method documented in this document describes a consistent method to assess the*immunity of equipment or a system against a defined phenomenon.*NOTE 2 – As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the*IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this*immunity test standard should be applied or not, and, if applied, they are responsible for defining the appropriate*test levels. Technical committee 77 and its sub-committees are prepared to co-operate with product committees in*the evaluation of the value of particular immunity tests for their products.
