This part of IEC 61000 deals with the limitation of harmonic currents injected into the public
It specifies limits of harmonic components of the input current which can be produced by
equipment tested under specified conditions.
This part of IEC 61000 is applicable 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
Arc welding equipment, which is not professional equipment, with a rated input current up
to and including 16 A per phase, is included in the scope of this document. All other arc welding
equipment is excluded from the scope of this document; however, the harmonics emission can
be evaluated using IEC 61000-3-12 and relevant installation restrictions.
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.
NOTE The words apparatus, appliance, device and equipment are used throughout this document. They have the
same meaning for the purposes of this document.
