IEC 61000-4-4:2012 is available as IEC Standards+ 61000-4-4:2012 which contains the International Standard and its Redline version (English only), showing all changes of the technical content compared to the previous edition. IEC 61000-4-4:2012 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It has the status of a basic EMC publication in accordance with IEC Guide 107. It gives immunity requirements and test procedures related to electrical fast transients/bursts. It additionally defines ranges of test levels and establishes test procedures. The object of this standard is to establish a common and reproducible reference in order to evaluate the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this standard describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This third edition cancels and replaces the second edition published in 2004 and its amendment 1 (2010). It constitutes a technical revision which improves and clarifies simulator specifications, test criteria and test setups.
