What is BS EN 61000-4-4:2012?
BS EN 61000-4-4 is a standard which 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.
Why buy it?
The standard gives specifications for laboratory and in situ tests. This is a revision and replaces BS EN 61000-4-4: 2004 and its amendment 1:2010. This revision improves and clarifies simulator specifications, test criteria and test setups.
What is it used for?
The standard is used in order to establish a common and reproducible reference by which 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. The standard defines:
• Test voltage waveform
• Range of test levels
• Test equipment
• Calibration and verification procedures of test equipment
• Test setups
• Test procedure
