Background

CISPR document 65A/922/CDV (IEC 61326 Ed 3) has been distributed to National Committees for comments with closing date 15/11/2019. If adopted without amendments, IEC 61326-1: 2019 Includes the following significant technical changes with respect to IEC 61326-1: 2013.

Changes

  • Emissions: Group and classes now apply as laid out in CISPR 11:2015/AMD 1:2016/AMD2:2019. For CLASS B EQUIPMENT with input current up to 16 A, IEC 61000-3-2 and IEC 61000-3-3 apply. For higher input currents up to 75 A per phase IEC 61000-3-12 and IEC 61000-3-11 apply as before
  • Electrostatic Discharge: No Significant changes
  • Electromagnetic field: Now requires 3V/m from 1.4GHz to 6GHz for basic and industrial environments. Originally this was 1V/m from 2GHz to 2.7GHz. This also considers battery operated devices as in Annex A
  • Voltage Dips: No longer required for controlled environments when applied to AC power (including protective earth)
  • Power frequency magnetic field: No Significant changes
  • Burst:  Optional 5KHz or 100KHz
  • Surge No Significant changes
  • Conducted RF No Significant changes
  • Instructions for use (NEW) The manufacturer shall give information that emissions, which exceed the levels required by this standard, can occur when equipment is connected to a test object.

Update DOC without testing?

No!

New requirement for Radiated Immunity above 1GHz.

Previous tests would have been done at 1V/m for 2GHz to 2.7GHz. Requirement has changed to 3V/M from 1.4GHz to 6GHz. Manufacturers should either consider retesting to the new level or carry out a risk assessment.
