IEC 61000-6-3 applies only if no relevant dedicated product or product family EMC emission standard has been published. This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use at residential locations. It also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4.
The intention is that all equipment used in the residential, commercial and light-industrial locations are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 apply. Equipment that has a radio function are also included in the scope of this standard. However, the emission requirements are not intended to be applied to the intentional transmissions from these radio transmitters, their harmonics and their out of band emissions. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within IEC 61000-6-3.
The objectives of IEC 61000-6-3 are:
— to establish requirements that provide an adequate level of protection of radio reception in the frequency range 9 kHz to 400 GHz,
— to establish requirements that provide an adequate level of protection against conducted and radiated electromagnetic disturbances emitted by equipment in the scope of this document,
— to support the reproducibility of measurement and the repeatability of results.
This edition includes some significant technical changes:
a) the addition of magnetic field emission requirements, including the measurement of WPT function,
b) the extension of low-voltage AC mains power requirements to cover the range 9 kHz to 150 kHz,
c) products with a radio function have been added to the scope,
d) limits in a FAR for rack mounted equipment have been added.
