New edition of CISPR 22 extends requirements for radiated emissions up to 6 GHz
" D# a* }2 X5 m  I

Geneva, Switzerland, 2008-10-15 – Following the successful launch of the Standards+ package in June 2008, the International Electrotechnical Commission (IEC) is now proposing a new International Standard with an annexed "Redline" version that keeps track of all changes from the previous edition.

The sixth edition of CISPR 22, Information technology equipment – Radio disturbance characteristics – Limits and methods of measurement, published in September 2008, establishes uniform requirements for the radio disturbance level of information technology equipment, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.

Martin Wright, Secretary of CISPR Subcommittee CIS/I: Electromagnetic compatibility (EMC) of information technology equipment, multimedia equipment and receivers, said: "CISPR 22 is one of the key EMC standards with the widest applicability since it specifies requirements for information technology equipment including telecommunications apparatus and PCs. It has been the cornerstone requirement for the emissions from these equipment for many years and is used across the world as the basis for compliance.

"The most significant change from the previous edition is the extension of the requirements for radiated emissions to cover the frequency band to 6 GHz. This reflects the latest technology in use in apparatus, with the highest frequency of measurement varying according to the technology. In addition the test arrangements have been modified and clarified and the method of measurement of emissions on telecommunication lines, for which no measurement network exists, has been updated.
