BS EN 61000-4-4:201261000-4-4 IEC:2012 7 ELECTROMAGNETIC COMPATIBILITY (EMC) Part 4-4: Testing and measurement techniques Electrical fast transient/burst immunity test 1 Scope This part of IEC 61000 relates to the immunity of electrical and electronic equipment to repetitive
37、 electrical fast transients. 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 eva
38、luate 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 part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defin
39、ed phenomenon. NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are respons
40、ible for determining the appropriate test levels and performance criteria.1The standard defines: test voltage waveform; range of test levels; test equipment; calibration and verification procedures of test equipment; test setups; test procedure. The standard gives specifications for laboratory and i
41、n situ tests. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
