Fully Anechoic Rooms for Radiated EMC Testing

Fully anechoic rooms (or FARs) are now included as certified test sites in the generic standard CISPR 16-1-4 Ed 3.2. Although limitations exist for floor standing equipment, they significantly reduce cost and facility requirements for many products.

No Sleeping in Seattle: A Recap of CISPR Projects from the 74th IEC General Meeting – Part 2

In this second installment of a two part article, we continue our review of the recent meeting of IEC-CISPR held in October 2010 in Seattle. In the first part of this article, we have described the current changes affecting the basic standard CISPR 16 and the activities of its experts within CISPR sub-committee (SC) A. We now take a look at the activities of the other CISPR sub-committees responsible for preparing the CISPR product standards. We also describe some of the projects shared by CISPR and IEC TC 77B (High Frequency Phenomena).

No Sleeping in Seattle: A Recap of CISPR Projects from the 74th IEC General Meeting

October 2010 saw the 74th IEC General meeting in Seattle, Washington, USA. Within the IEC, its special committee CISPR (Comite International Special des Perturbations Radioelectriques –International Special Committee on Radio Interference) came together and this article reviews some of the key projects discussed at that meeting. The activities of IEC TC 77, a parallel committee to CISPR developing the IEC 61000 series and of equal importance, did not meet in Seattle and hence will not be discussed here except for the JTFs (Joint Task Forces) that exist in common with CISPR Subcommittee A, responsible for the basic standard CISPR 16, which will be the main focus of this first part of a two part article. In the second part of the article (to be published in a subsequent edition of this magazine), we will continue with the CISPR product standards and the Joint Task Forces (JTFs) existing between the different subcommittees as well as between CISPR subcommittees and IEC SC 77 B.

Update on CISPR Standards: What’s New Above 9 kHz

The global recession has not prevented EMC standardization work from marching relentlessly forward. Work within CISPR is no exception and this year delegates and experts will meet in Lyon, France in September under the auspices of the current chairman Don Heirman (US) and secretary Steve Colclough (UK). For those of you new to EMC, CISPR is an international special committee on radio interference within the International Electrotechnical Commission (IEC). As defined on the IEC website for CISPR, 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). Following is a brief overview of the scope of CISPR’s current activities in 2009, close to 75 years after its founding in 1935.
