Establishes uniform requirements for the conduction and the radiation of radio-frequency disturbances from appliances whose main functions are performed by motors and switching or regulating devices, unless the the r.f. energy is intentionally generated or intended for illumination.

1.1 This standard applies to the conduction and the radiation of radio-frequency disturbancesfrom appliances whose main functions are performed by motors and switching or regulatingdevices, unless the r.f. energy is intentionally generated or intended for illumination.It includes such equipment as: household electrical appliances, electric tools, regulatingcontrols using semiconductor devices, motor-driven electro-medical apparatus, electric/ electronic toys, automatic dispensing machines as well as cine or slide projectors.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.This standard gives for the time being no requirements for apparatus that cannot be measured on a test site; requirements for in situ measurements are under consideration.Excluded from the scope of this standard are:– apparatus for which all emission requirements in the radio frequency range are explicitlyformulated in other IEC or CISPR standards;NOTE 1 Examples are:−luminaires, including portable child-appealing luminaires, discharge lamps and other lighting devices: CISPR 15;−audio and video equipment and electronic music instruments, other than toys: CISPR 13 and CISPR 20 (see also 7.3.5.4.2);−mains communication devices, as well as baby surveillance systems: IEC 61000-3-8;−equipment for generation and use of radio frequency energy for heating and therapeutic purposes: CISPR 11;−microwave ovens: CISPR 11 (but be aware of 1.3 on multifunction equipment);−information technology equipment, e.g. home computers, personal computers, electronic copying machines: CISPR 22;−electronic equipment to be used on motor vehicles: CISPR 12;−radio controls, walkie-talkies and other types of radio-transmitters, also when used with toys.– regulating controls and equipment with regulating controls incorporating semiconductordevices with a rated input current of more than 25 A per phase;– stand-alone power supplies.NOTE 2 Toys powered by the supply system of a motor-powered vehicle, ship or aircraft are not covered by this standard.1.2 The frequency range covered is 9 kHz to 400 GHz.1.3 Multifunction equipment which is subjected simultaneously to different clauses of thisstandard and/or other standards shall meet the provisions of each clause/standard with therelevant 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 thesuppression 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.
