1.1 This standard applies to the conduction and radiation of radio-frequency disturbances
from appliances whose main functions are performed by motors, switching or regulating
devices, or by r.f. generators used in induction cooking appliances.

It includes such equipment as: household electrical appliances, electric tools, regulating
controls using semiconductor devices, motor-driven electro-medical apparatus, electric/
electronic toys, automatic dispensing machines as well as cine or slide projectors. Both mains
powered appliances and battery powered appliances are included.

Also included in the scope of this standard are:

– separate parts of the above mentioned equipment such as motors, switching devices e.g.
(power or protective) relays, however no emission requirements apply unless formulated in
this standard.

Excluded from the scope of this standard are:

– apparatus for which all emission requirements in the radio frequency range are explicitly
formulated in other IEC or CISPR standards;

– regulating controls and equipment with regulating controls incorporating semiconductor
devices with a rated input current of more than 25 A per phase;

– stand-alone power supplies.

1.2 The frequency range covered is 9 kHz to 400 GHz.

1.3 Multifunction equipment which is subjected simultaneously to different clauses of this
standard and/or other standards shall meet the provisions of each clause/standard with the
relevant functions in operation; details are given in 7.2.1.

1.4 The limits in this standard have been determined on a probabilistic basis, to keep the
suppression of disturbances economically feasible while still achieving an adequate radio
protection. In exceptional cases radio frequency interference may occur, in spite of
compliance with the limits. In such a case, additional provisions may be required.

1.5 The effects of electromagnetic phenomena relating to the safety of apparatus are
excluded from the scope of this standard.
