IEC 61000-4-12:2017
Electromagnetic Compatibility (EMC) - Part 4-12: Testing and measurement techniques - Ring wave immunity test
IEC 61000-4-12:2017 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to ring waves occurring in low-voltage power, control and signal lines supplied by public and non-public networks.
The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to ring waves. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
It has the status of a basic EMC publication in accordance with IEC Guide 107.
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of a mathematical modelling of ring wave waveform;
b) new Annex B on selection of generators and test levels;
c) new Annex C on explanatory notes;
d) new Annex D on measurement uncertainty;
e) addition of high speed CDN;
f) addition of a calibration procedure for CDN.
