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). As its full name implies, CISPR's principal task is at the higher end of the frequency range, from 9 kHz upwards, preparing standards that offer protection of radio reception from interference sources such as electrical appliances of all types, the electricity supply system, industrial, scientific and electromedical RF, broadcasting receivers (sound and TV) and, increasingly, IT equipment (ITE).
There is a subcommittees working under this standardization. CISPR's work involves equipment and methods for measuring interference, establishing limits and immunity requirements, and prescribing (in liaison with other IEC technical committees) methods of measuring immunity. The committee also takes account of the impact of safety regulations on interference suppression of electrical equipment. The scopes of the various subcommittees are listed below,
• CIS/A covers radio-interference measurements and statistical methods
• CIS/B handles interference relating to industrial, scientific and medical RF apparatus
• CIS/D deals with EM disturbances related to electric and electronic equipment on vehicles and devices powered by internal-combustion engines
• CIS/F covers interference relating to household appliances, tools, lighting and similar equipment
• CIS/H sets limits for the protection of radio services, and
• CIS/I, formed in 2001 from the former CIS/E and CIS/G, deals with EMC of information technology equipment (ITE), multimedia equipment and receivers.
In addition, CISPR has a steering committee known as SC S. In some technical areas, there is the possibility of overlap in the standards adopted by CISPR and those of other IEC and ISO technical committees. Where this involves emission and immunity of devices other than receivers, CISPR considers the requirements jointly with the appropriate committee.
In the event of new technological convergence, it is difficult to decide whether some products should be designed to television or to computer EMC standards. This results in some manufacturers having to test their multimedia products to both, which is costly and time-consuming for industry. Hence, the CISPR SC I is working to produce new EMC standards for these multimedia products. Meanwhile, the existing product standards (CISPR 13, 20, 22 and 24) will continue to be fully maintained for the foreseeable future.
To produce new EMC standard, a document is prepared in order to provide guidance in the selection of appropriate CISPR EMC Standards applicable to your products, systems and installations. This document must also give an overview of the latest version of published CISPR Standards covering EMC aspects of products, systems and installations.
