Specifies the harmonic requirements for equipment with a current input less than or equal to 16 A intended for connection to an electrical network.

This part of AS/NZS 61000 deals with the limitation of harmonic currents injected into the public supply system. 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 part of AS/NZS 61000 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. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this standard and may be subject to installation restrictions as indicated in IEC 61000-3-4. NOTE 1 It is intended to replace technical report IEC 61000-3-4 by an international standard, IEC 61000-3-12 (under consideration). 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. NOTE 2 The words apparatus, appliance, device and equipment are used throughout this standard. They have the same meaning for the purpose of this standard.
