BS EN 55024:2010 pdf free.Information technology equipment – Immunity characteristics – Limits and methods of measurement.
This CISPR publication applies to information technology equipment (ITE) as defined in
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 o Hz to 400 GHz for electromagnetic phenomena.
The test requirements are specified for each port considered.
NOTE 1 Safely 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 Ihese instances. special mitigahon measures may have to be employed.

For the purposes of this document, the terms and definitions given in IEC 60050-161. and the following apply.
unwanted change in operational performance of an EUT due to electromagnetic disturbances. This does not necessarily mean malfunction or catastrophic failure
3.2 equipment under test EUT representative device or functionally interactive group of devices (that is a system) which includes one or more host units that is subjected to test procedures specified in this publication
3.3 information technology equipment ITE any equipment:
a) which has a primary function of either (or a combination of) entry, storage, display, retrieval, transmission, processing, switching, or control, of data and of telecommunication messages and which may be equipped with one or more terminal ports typically operated for information transfer;
b) with a rated supply voltage not exceeding 600 V.
It includes, for example, data processing equipment, office machines, electronic business equipment and telecommunication equipment.
Any equipment (or part of the ITE equipment) which has a primary function of radio transmission andlor reception according to the ITU Radio Regulations are excluded from the scope of this publication.BS EN 55024 pdf download.
