EN 61000-4-4 Regulatory Compliance & Certification Testing

EN 61000-4-4 EMC Immunity Testing of Electrical Fast Transient/Bursts

EN 61000-4-4 test standard relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. EN 61000-4-4 test labs provide immunity requirements and test procedures related to electrical fast transients/bursts. EN 61000-4-4 testing additionally defines ranges of test levels and establishes test procedures.

Summary of EN 61000-4-4 Immunity Testing of Electrical Fast Transients/Bursts

EN 61000-4-4 testing establishes a common and reproducible reference for evaluating the immunity of electrical and electronic equipment. The equipment has to be first subjected to electrical fast transients/bursts on supply, signal, control, and earth ports. The EN 61000-4-4 test method assesses the immunity of an equipment or system against a defined phenomenon.

EN 61000-4-4 defines:

  • test voltage waveform
  • range of test levels
  • test equipment
  • verification procedures of test equipment
  • test set-up
  • test procedure

EN 61000 4 4 testing gives specifications for laboratory and post-installation tests. The repetitive fast transient test is a test with bursts consisting of several fast transients, coupled into a power supply, control, signal, and earth ports of electrical and electronic equipment. 

The test is intended to demonstrate the immunity of electrical and electronic equipment. However, only when subjected to types of transient disturbances such as those originating from switching transients. This may include interruption of inductive loads, relay contact bounce, etc.
