scope:

This Standard specifies the limitation of harmonic currents flowing into the commercial power supply systems. It also 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 Annex A and Annex B. The tests according to this Standard are type tests. Test conditions for particular equipment are given in Annex C.

The Standard is applicable to electrical and electronic equipment (household electrical appliances and general-purpose products) (hereafter referred to as the "equipment") having rated current up to and including 20 A per phase, and intended to be connected to the commercial power supply systems of 300 V or less. However, even when this Standard is applied beyond this range, the application with necessary modification is not precluded.

Arc welding equipment which is not the professional equipment is within the scope of this Standard.

Arc welding equipment intended for professional use as specified in JIS C 9300-1 is out of the scope of this Standard.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 61000-3-2 : 2005 Electromagnetic compatibility (EMC) - Part 3-2 : Limits - Limits for harmonic current emissions (equipment input current:5 16 A per phase), Amendment 1 : 2008 and Amendment 2 : 2009 (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
