New IEC 61000-3-3 3rd Edition on Electromagnetic Compatibility (EMC)

EMC Compliance is an important part of many electrical engineer’s jobs.  So changes to the major EMC standards are critical to track.  One such new update is the IEC 61000-3-3 Edition 3.0, “Electromagnetic compatibility (EMC) – Part 3-3: Limits – Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current < or = 16 A per phase and not subject to conditional connection.”   The document covers  the limitation of voltage fluctuations and flicker impressed on the public low-voltage system.

IEC 61000-3-3 2013 contains 4 Annexes in addition to the body of the text.  They cover:

  • Application of limits and type test conditions for specific
  • Test conditions and procedures for measuring d max voltage changes caused by manual switching
  • Determination of steady state voltage and voltage change
    characteristics, as defined in IEC 61000-4-15:2010 max voltage changes caused by manual switching
  • Input relative voltage fluctuation ΔV/V for Pst = 1,0 at output
    [IEC/TR 61000-3-7:2008]

This third edition cancels and replaces the second edition published in 2008.  The bilingual edition now available contains first the English language text and then the French.  It is a technical revision generated to harmonize the IEC 61000-3-3 with changes made in IEC 61000-4-15:2010.  A redline edition is available, should you want to have the changes defined.

The IEC 61000 series on EMC, Electromagnetic Compatibility, is organized into 6 distinct parts:  Part 1: General, Part 2:  Environment, Part 3: Limits, Part 4: Testing and measurement techniques, Part 5: Installation and mitigation guidelines, and Part 9: Miscellaneous.
