Scope of this Standard

Applies to information technology equipment (ITE) as defined in CISPR 22. Procedures are defined for the measurement of ITE and limits are specified which are developed for ITE and within the frequency from 0 Hz to 400 GHz. The object of this publication is to establish requirements which will provide an adequate level of intrinsic immunity so that the equipment will operate as intended in its environment. For exceptional environmental conditions, special mitigation measures may be required. Owing to testing and performance assessment considerations, some test are specified in defined frequency bands or at selected frequencies. Equipment which fulfills the requirements at these frequencies is deemed to fulfill the requirements in the entire frequency range from 0 Hz to 400 GHz for electromagnetic phenomena. The object of this publication is to define the immunity test requirements for equipment defined in the scope in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges (ESD) The test requirements are specified for each port considered.
