IEC 61000-4-4:2004

Relates to the immunity requirements and test methods for electrical and electronic equipment to repetitive electrical fast transients. Additionally defines ranges of test levels and establishes test procedures. The object of this standard is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to repetitive fast transients (bursts), on supply, signal and control ports. The test is intended to demonstrate the immunity of electrical and electronic equipment when subjected to types of transient disturbances such as those originating from switching transients (interruption of inductive loads, relay contact bounce, etc.). The standard defines: - test voltage waveform; - range of test levels; - test equipment; - test set-up; - test procedure.

Introduces additional requirements for the calibration of the fast transient/ burst generator. The intention is to improve the reproducibility of the test.

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.
