IEC 61000-3-2-2018 pdf free download.Electromagnetic compatibiity (EMC) – Part 3-2: Limits – Limits for harmonic current emissions (equipment input currents 16 A per phase).
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 distribution systems.
Arc welding equipment which is not professional equipment, with a rated input current up to and including 16 A per phase, is included in this document. 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.
NOTE The words apparatus, appliance, device and equipment are used throughout this document. They have the same meaning for the purposes of this document.

4 General
The objective of this document is to set limits for harmonic emissions of equipment within its scope, so that, with due allowance for the emissions from other equipment, compliance with the limits ensures that harmonic disturbance levels do not exceed the compatibility levels defined in IEC 61000-2-2.
Professional equipment that does not comply with the requirements of this document can be permitted to be connected to certain types of low voltage supplies, if the instruction manual contains a requirement to ask the supply utility for permission to connect. Recommendations concerning this aspect are contained in IEC 61000-3-12.
5 Classification of equipment
5.1 General
For the purpose of harmonic current limitation, equipment is classified as follows:
Class A:
Equipment not specified as belonging to Class B, C or D shall be considered as Class A equipment.
Some examples of Class A equipment are:
— balanced three-phase equipment;
— household appliances, excluding those specified as belonging to Class B, C or D;
— vacuum cleaners;
— high pressure cleaners;
— tools, excluding portable tools;
— independent phase control dimmers;
— audio equipment;
— professional luminaires for stage lighting and studios.
NOTE 1 Equipment that can be shown to have a significant effect on the supply system might be reclassified in a future edition of this document, taking into account the following factors:
— number of pieces of equipment in use:
— duration of use:
— simultaneity of use;
— power consumption.IEC 61000-3-2 pdf free download.
