This CISPR publication applies to information technology equipment (ITE) as defined in
CISPR 22.
The object of this publication is to establish requirements that will provide an adequate level of
intrinsic immunity so that the equipment will operate as intended in its environment. The
publication defines the immunity test requirements for equipment within its scope in relation to
continuous and transient conducted and radiated disturbances, including electrostatic
discharges (ESD).
Procedures are defined for the measurement of ITE and limits are specified which are
developed for ITE within the frequency range from 0 Hz to 400 GHz.
For exceptional environmental conditions, special mitigation measures may be required.
Owing to testing and performance assessment considerations, some tests are specified in
defined frequency bands or at selected frequencies. Equipment which fulfils the requirements
at these frequencies is deemed to fulfil the requirements in the entire frequency range from
0 Hz to 400 GHz for electromagnetic phenomena.
The test requirements are specified for each port considered.
NOTE 1 Safety considerations are not covered in this publication.
NOTE 2 In special cases, situations will arise where the level of disturbance may exceed the levels specified in
this publication, for example where a hand-held transmitter is used in proximity to equipment. In these instances,
special mitigation measures may have to be employed.
