It specifies limits of harmonic components of the input current which may be produced by equipment tested under specified conditions.
Harmonic components are measured according to Annexes A and B.
This standard is applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems.
Arc welding equipment which is not professional equipment, with input current up to and including 16 A per phase, is included in this standard.
The tests according to this standard are type tests. Test conditions for particular equipment are given in Annex C.
