Description of BS EN 55014-1:2017+A11:2020 2020

This part of CISPR 14 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools and similar apparatus as defined below, whether powered by AC or DC (including a battery).

Within this standard wherever the term “equipment” is used it includes the more specific terms “appliance”, “household or similar appliances”, “electric tool”, “toys” and “apparatus”.

This International Standard is applicable to the following equipment:

• household appliances or similar equipment;

  NOTE 1 Examples are equipment used:

  • for typical housekeeping functions in the household environment, which includes the dwelling and its associated buildings, the garden, etc.;

  • for typical housekeeping functions in shops, offices, commercial and other similar working environments;

  • in farms;

  • by clients in hotels and other residential type environments;

  • for induction cooking, either in residential or commercial environments.

• electric tools;

  NOTE 2 Examples of electric tools include electric motor-operated or electromagnetically driven hand-held tools, transportable tools, lawn and garden machinery.

• similar apparatus.

  NOTE 3 Examples are external power controllers using semiconductor devices, motor-driven electro-medical apparatus, electric/electronic toys, automatic goods-dispensing machines, entertainment machines, cine or slide projectors, as well as battery chargers and external power supplies for use with products under the scope of this standard.

  Also included in the scope of this standard are separate parts of the above mentioned equipment such as motors and switching devices (e.g. power or protective relays); however, no emission requirements apply to such separate parts, unless otherwise stated in this standard.

  Excluded from the scope of this standard are:

  • equipment for which all emission requirements in the radio-frequency range are explicitly formulated in other CISPR standards;

    NOTE 4 Examples are:

    • luminaires, including portable luminaires for children, discharge lamps and other lighting devices under the scope of CISPR 15;

    • information technology equipment, e.g. home computers, personal computers, electronic copying machines under the scope of CISPR 32;

    • audio/video equipment and electronic music instruments other than toys under the scope of CISPR 32;

    • mains communication devices, as well as baby surveillance systems;

    • equipment which is under the scope of CISPR 11 because of the use of radio frequency energy for heating (other than induction cooking) and therapeutic purposes, microwave ovens (but be aware of 6.5 on multifunction equipment e.g. for click measurements)

    • radio controls, walkie-talkies and other types of radio-transmitters;

    • arc welding equipment.

• equipment intended to be used only on a vehicle, ship or aircraft;

• the effects of electromagnetic phenomena relating to the safety of the equipment.

Multifunction equipment may be required to comply with clauses in this and other standards. The details are given in 6.5.

The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions.
