NEW!IEC 61000-4-12:2017 is available as IEC 61000-4-12:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC61000-4-12:2017 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 IEC61000 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.
