Defines general terms and terms concerning impedances, harmonics, voltage changes and flicker.
Applicable to electrical and electronic equipment for household and similar use, intended to be connected to low-voltage a.c. distribution systems. Gives general requirements and maximum permissible values of harmonics components of the input current which may be produced by a piece of equipment tested individually under specified conditions, practical methods of type tests and guidance on the practical application of the requirements. The second impression (1991) includes Amendments 1, 2 and 3.
Specifies limits for harmonic current emissions 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. The tests according to this standard are type tests. Test conditions for particular equipment are given in annex C. For systems with nominal voltages less than 220 V (line to neutral), the limits have not yet been considered.
