CISPR

The Comité International Spécial des Perturbations Radioélectriques (CISPR; English: International Special Committee on Radio Interference) was founded in 1934 to set standards for controlling electromagnetic interference in electrical and electronic devices, and is a part of the International Electrotechnical Commission (IEC).

Organization

CISPR is composed of six subcommittees, each responsible for a different area, defined as:

Technical standards

CISPR 11

CISPR 11 is analog standard to European standard EN 55011. This is the standard that is very often referenced in all European EMC standards, defining measurement methods, measurement equipment, limit lines and interpretation of applicability of limit lines, starting from household appliances to medical devices.

CISPR 22

CISPR 22 is analog standard to European standard EN 55022. This is the standard that is very often referenced in all European EMC standards, defining measurement methods, measurement equipment, limit lines and interpretation of applicability of limit lines, starting from household appliances to medical devices.

EN 55022 Information technology equipment. Radio disturbance characteristics. Limits and methods of measurement.

Scope

Standard EN 55022 is applicable to information technology equipment (ITE). It defines information technology equipment as any equipment or device that operates with a rated supply voltage not exceeding 600V, has a main function of entry, storage, display, retrieval, transmission, processing, switching, or control of data and equipment that could be used in combination with one or more terminal ports with the main function– information transfer. Equipment or device, with a main function of radio transmission or reception are not covered by standard EN 55022.
