EN 55024 is equivalent to CISPR 24 and applies to, as the name implies, information technology equipment (ITE). EN 55024 defines the immunity test requirements for information technology equipment in relation to continuous and transient conducted and radiated disturbances. Tests within the standard include Electrostatic Discharges (ESD), Electrical Fast Transients (EFT), Surge, Power Frequency Magnetic Fields, Power interruptions, Radio Frequency Interference (RFI). EN 55024 establishes requirements that will provide an adequate level of intrinsic immunity so that the equipment will operate as intended in its environment. The test requirements are specified and applied on port by port approach. Ports are defined and described within the standard. The ports include the overall enclosure, DC Power, AC Power, Earth, Signal, and finally Telecommunication ports.
