New BS EN 55022:2010 just released on Information technology equipment – Radio disturbance characteristics – Limits and methods of measurement

The new BS EN 55022 2010 Edition has just been released for public distribution.  It’s titled “Information technology equipment. Radio disturbance characteristics. Limits and methods of measurement,” and is the official English language edition of the EN 55022:2010.  The standard is a modified adoption of the CISPR 22 6th Edition from 2008.

The standard applies to information technology equipment (ITE). Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified. The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.

BS EN 55022 applies to 2 EU Directives: EMC Electromagnetic Compatibility (2004/108/EC) and RTTE Radio and telecommunications terminal equipment (1999/5/EC).  It replaces the BS EN 55022:2006+A2:2010 Edition, which remains current.

This standard, and all BS documents, are available from Document Center Inc. via our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We can help you with questions regarding the EN standards, as well as all your other conformance documentation requirements.

 

New Amendment A2 issued for BS EN 55022 2006 Edition on Radio Disturbance Characteristics

The BS EN 55022:2006 — Information technology equipment, Radio disturbance characteristics, Limits and methods of measurement — has just been modified by Amendment A2 dated 3/1/2011.  The consolidated BS EN 55022:2006+A2:2010 supersedes (replaces) the BS EN 55022:2006+A1:2007, which will be withdrawn on December 1, 2013.

This new BS EN 55022 (the Official English language edition of EN 55022) is an adoption of the CISPR 22, 5th Edition,  with modifications.  The differences in the 2 documents are noted by specific tags within the EN copy.  Tags also define the changes generated by the 2 amendments, A1 and A2.

Since the CISPR 22 standard has recently been revised to the 6th Edition, there may be some question as to why the EN edition of the same source material is lagging behind.  With these documents that originate with IEC and then are adopted at the European regional level by CENELEC,  there is often a greater necessity for modifications and a longer adaption period for the countries affected.  This reflects the inherent difficulties generated by standards having to do with electricity, where protocols for its usage vary from country to country and region to region.

Since the BS EN 55022:2006+A2:2010 is interfiled, the document must be repurchased in its entirety.   The standard (and all BSI and BS EN specifications) are available from Document Center Inc. on our website, www.document-center.com.  Or you may contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  All questions are welcome.
