|| IEC 61000-4-11 ed2.0 withdrawn corrigendum
|| Electromagnetic compatibility (EMC) - Part 4-11: Testing and
measurement techniques - Voltage dips, short interruptions and
voltage variations immunity tests
||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 standard 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 a.c. networks.
It does not apply to electrical and electronic equipment for
connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards.
The object of this standard 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.
This second edition cancels and replaces the first edition published in 1994 and its amendment 1 (2000). This second edition constitutes a technical revision in which
1) preferred test values and durations have been added for the
different environment classes;
2) the tests for the three-phase systems have been specified.
It has the status of a Basic EMC Publication in accordance with IEC
