BS EN 55014-2:1997+A2:2008, CISPR 14-2:1997

1.1 This standard deals with the electromagnetic immunity of appliances and similar apparatus for
household and similar purposes that use electricity, as well as electric toys and electric tools, the rated
voltage of the apparatus being not more than 250 V for single-phase apparatus to be connected to phase
and neutral, and 480 V for other apparatus.
Apparatus may incorporate motors, heating elements or their combination, may contain electric or
electronic circuitry, and may be powered by the mains, by transformer , by batteries, or by any other
electrical power source.
Apparatus not intended for household use, but which nevertheless may require the immunity level, such
as apparatus intended to be used by laymen in shops, in light industry and on farms, are within the scope
of this standard, a s far as they are included in CISPR 14-1 , and in addition:
— microwave ovens for domestic use and catering;
— cooking hobs and cooking ovens, heated by means of r.f. energy, (single- and multiple-zone) induction
cooking appliances;
— appliances for personal care equipped with radiators in the range from UV to IR, inclusive
(this includes visible light).
1.2 This standard does not apply to:
— equipment for lighting purposes;
— apparatus designed exclusively for heavy industrial purposes;
— apparatus intended to be part of the fixed electrical installation of buildings (such as fuses, circuit
breakers, cables and switches);
— apparatus intended to be used in locations where special electromagnetic conditions prevail, such as
the presence of high e.m. fields (for example in the vicinity of a broadcast transmitting station), or where
high pulses occur on the power network (such as in a power generator station);
— radio and television receivers, audio and video equipment, and electronic music instruments other
than toys ;
— medical electrical appliances;
— personal computers and similar equipment other than toys ;
— radio transmitters;
— apparatus designed to be used exclusively in vehicles;
— babies surveillance systems.
1.3 Immunity requirements in the frequency range 0 Hz to 400 GHz are covered.
1.4 The effects of electromagnetic phenomena relating to the safety of apparatus are excluded from this
standard and are covered by other standards, for example IEC 335.
Abnormal operation of the apparatus (such as simulated faults in the electric circuitry for testing purposes)
is not taken into consideration.
NOTE Attention is drawn to the fact that additional requirements may be necessary for apparatus intended to be used on board
ships or aircraft.
1.5 The object of this standard is to specify the immunity requirements for apparatus defined in the scope
in relation to continuous and transient, conducted and radiated electromagnetic disturbances, including
electrostatic discharges.
These requirements represent essential electromagnetic compatibility immunity requirements.
NOTE In special cases situations will arise where the level of disturbances may exceed the test values specified in this standard. In
these instances special mitigation measure may have to be employed.

CISPR 14-2:2020 specifies the electromagnetic immunity requirements in the frequency range 0 Hz to 400 GHz that apply to appliances, electric tools and similar equipment as specified below, whether powered by AC or DC (including a battery). This document specifies immunity requirements for continuous and transient electromagnetic disturbances, both conducted and radiated. Unless otherwise specified, this document is applicable to all equipment in the scope of CISPR 14-1, namely:

- household appliances or similar equipment;

- electric tools;

- similar equipment;

- Refer to the Scope of the document for examples of equipment.

Included in the scope of this document are also microwave ovens for domestic use or catering.

Equipment which incorporate radio transmit/receive functions are included in the scope of this document. NOTE: For handling cases where equipment under the scope of this document is combined with transmit and/or receive radio functions, see Clause 8.

Excluded from the scope of this document are:

- equipment for which all electromagnetic immunity requirements are explicitly formulated in other CISPR or IEC standards;

- equipment intended to be part of the fixed electrical installation of buildings (e.g. fuses, circuit breakers, cables and switches);

- medical electrical equipment, including those in the scope of CISPR 14-1;

- equipment used only in industrial environment;

- equipment intended to be used exclusively in locations where special electromagnetic conditions exist (e.g. high electromagnetic fields nearby broadcast transmitting stations or high energy pulses nearby power generation stations);

- equipment intended to be used exclusively on a vehicle, ship, boat or aircraft;

- the effects of electromagnetic phenomena relating to the safety of apparatus (see IEC 60335 series);

Also excluded from the scope of this document is AC single-phase equipment with a rated voltage higher than 250 V between phase and neutral and AC multi-phase equipment with rated voltage higher than 480 V. Abnormal operation of the equipment, such as simulated faults in the electric circuitry for testing purposes, is not taken into consideration.

This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

a) extension of the frequency range for radiated immunity above 1 GHz;

b) an advanced categorisation of equipment;

c) revision of general test conditions and addition of new specific test conditions (e.g. for robotic equipment);

d) clarification of requirements applicable to equipment incorporating radio functions;

e) addition of requirements for wired network ports;

f) revision of definitions and addition of new ones;

g) delete requirements referring to statistical evaluation.
