Scope

This document 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 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 of GB/T 17626 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.
