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.

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.
