<!-- NEW! -->IEC 61000-4-11:2020 is available as <a href="https://webstore.iec.ch/publication/66487">IEC 61000-4-11:2020 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>IEC 61000-4-11:2020 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. This third edition cancels and replaces the second edition published in 2004 and Amendment 1:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

- rise time and fall time of transients are now defined terms in Clause 3;

- the origin of voltage dips and short interruptions is now stated in Clause 4.

Keywords: immunity test methods, low-voltage power supply networks
