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

2Scope / Description

Scope
This document specifies methods for evaluating electromagnetic compatibility (EMC) immunity, along with preferred test levels for voltage dips, short interruptions, and voltage variations for electrical and electronic equipment connected to low-voltage networks.

It applies to electrical and electronic equipment with a rated input current not exceeding 16 A per phase when connected to 50 Hz or 60 Hz AC mains.

It does not apply to equipment connected to 400 Hz AC mains. Test requirements for such networks are to be addressed in future IEC documents.

The objective of this document is to establish a general basis for assessing the immunity of electrical and electronic equipment under conditions of voltage dips, short interruptions, and voltage variations.

NOTE 1: Voltage fluctuation immunity testing is covered by IEC 61000-4-14.

The test method described in this document provides a unified approach for assessing the immunity of equipment or systems to specified disturbances.

NOTE 2: As outlined in IEC Guide 107, this is a base publication for use by IEC product committees. IEC Guide 107 further states that IEC product committees are required to determine the applicability of this immunity standard and, where applicable, define the relevant test levels. Technical Committee 77 and its subcommittees are prepared to collaborate with product committees to evaluate the specific immunity test values for their products.
