AS/NZS CISPR 24:2002

Establishes the unifrom requirements for the electromagnetic immunity of information technology equipment and specifies applicable tests, test levels, product operating conditions and assessment criteria. This Standard is identical to and has been reproduced from CISPR 24:1997.

This CISPR publication 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 range 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 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 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.NOTES1 Safety considerations are not covered in this publication.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 an equipment. In these instances special mitigation measures may have to be employed.
