IEC 61000-3-2: Limits - Limits for Harmonic Current Emissions (equipment input current up to and...
Standard Overview
IEC 61000-3-2 deals with the limitation of harmonic currents injected into the public supply system. IEC 61000-3-2 specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions. This standard applies to electrical and electronic equipment having a rated input current up to and including 16 A per phase, and intended to be connected to public low‑voltage distribution systems.
Note: Advanced Test Equipment Rentals can perform ISO17025 accredited calibration on products that abide by this standard.

Arc welding equipment which is not professional equipment, with a rated input current up to and including 16 A per phase, is included in IEC 61000-3-2. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this document and can be subject to installation restrictions as indicated in IEC 61000-3-12.
The tests according to this document are type tests. For systems with nominal voltages less than but not equal to 220 V (line-to-neutral), the limits have not yet been considered.
This fifth edition, IEC 61000-3-2:2018, cancels and replaces the fourth edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes from the previous edition:
a) an update of the emission limits for lighting equipment with a rated power ≤ 25 W to take into account new types of lighting equipment;
b) the addition of a threshold of 5 W under which no emission limits apply to all lighting equipment;
c) the modification of the requirements applying to the dimmers when operating non‑incandescent lamps;
d) the addition of test conditions for digital load side transmission control devices;
e) the removal of the use of reference lamps and reference ballasts for the tests of lighting equipment;
f) the simplification and clarification of the terminology used for lighting equipment;
g) the classification of professional luminaires for stage lighting and studios under Class A;
h) a clarification about the classification of emergency lighting equipment;
i) a clarification for lighting equipment including one control module with an active input power ≤ 2 W;
j) an update of the test conditions for television receivers;
k) an update of the test conditions for induction hobs, taking also into account the other types of cooking appliances;
l) for consistency with IEC 61000-3-12, a change of the scope of IEC 61000-3-2 from equipment with an input current ≤ 16 A to equipment with a rated input current ≤ 16 A.
