Last year ended with the usual EMC standards
activity we got used to earlier in the year. It always amazes
me that there is no “down time” from working standards
in our discipline.
Status of IEEE EMC Standards
To end the 2006 edition of our standards activity, our EMCS Standards
Development Committee met in Houston hosted by Board member Bob
Scully who works at NASA, literally across the street from the
hotel where we met. Stephen Berger chaired our SDCom meeting,
which included this time a long discussion on updating the SDCom
page on the Society’s web site. Mike Hart and his daughter,
Natalie Hart, led the discussion and coordinated the changes with
Natalie taking the lead. You will see the progress if you visit
the EMCS web site and then click on the Standards button in the
left hand column (www.emcs.org).
Once there, click on the “click here to read more”
and you will see the progress and the work still in process. We
also added a link to the IEEE Standards Association web site to
get the EMCS standards of interest (and a vast array of others)
on line.
The meeting continued with a progress report on our cadre of EMC
standards. The full titles and abstracts are found by going to
the IEEE Standards Association web site on www.standards.ieee.org,
clicking on “shop”, and typing in the standard number.
From there, you then get the information on the standard and how
to order it. Here is a brief review of the progress so far for
each active standard:
1. IEEE 139: Measurement of emissions from industrial, scientific
and medical equipment. Status: Reaffirmation of the standard is
completed and it is now current.
2. IEEE 187: Measurement of emissions from television receiver.
Status: This will be balloted for reaffirmation.
3. IEEE 299.1: Measurement of shielding effectiveness of small
enclosures. Status: Approved project by the IEEE Standards Board.
4. IEEE 473: EM site survey measurements. Status: New project
authorization by the Standards Board needed to continue the work.
(The new chair is Vil Arafils.)
5. IEEE 475: RF intrusion emission measurements. Status: Reaffirmation
was approved by the SDCom.
6. IEEE 1128: Performance of RF absorber material. Status: Current.
7. IEEE 1140: Measurement of fields from VDTs. Status: Current.
8. IEEE 1302: Characteristics of RF gaskets. Status: Draft for
balloting soon.
9. IEEE 1309: Probe calibration. Status: Seeking new chair of
working group.
10. IEEE 1560: RF filter performance. Status: Current.
11. IEEE 1597.1 and 1597.2: Computational EM. Status: Ballot in
early 2007.
12. IEEE 1642 and 1643: Intentional EMI. Status: First draft underway.
13. IEEE 1688: Line replaceable module testing. Status: Progress
on first draft.
14. IEEE 1775: Broadband Powerline EMC measurements. Status: Working
with the Power Engineering Society to define contributions from
each Society to the document.
15. IEEE 1900 series of standards: Software Defined Radio Conformity.
Status: Work is proceeding working with the Communications Society.

Natalie and Mike Hart (center) keep
busy! In August, they staffed their Quantum Change booth at
the EMC Symposium in Portland and are shown with Steve Linthicum
(left) and Glenn Shelby (right), both with NASA in Huntsville,
Alabama. In November, they were active contributors to the
EMC Society Standards activity, participating in the SDCom
meeting in Houston, Texas. |
As you can see, we continue to work our projects including cooperating
with other IEEE Societies where the scope of the standard embraces
their work as well as ours. For more information, contact the
SDCom chair: Stephen Berger (Stephen.berger@ieee.org)
or the secretary Ed Hare (w1rfi@arrl.org

ACEC Meeting Report from Geneva, Switzerland
In early December, there was an international EMC meeting of the
Advisory Committee on EMC (ACEC) which reports to the technical
management committee of the International Electrotechnical Commission
(IEC). This committee is called the Standardization Management
Committee. The meeting was in Geneva, Switzerland and was attended
by many IEC committees with EMC in their scopes including TC77
(EMC) and the Special International Committee on Radio Interference
(CISPR) as well as other TCs such as TC62 on medical device standards
and TC46 on cabling. Bill Radasky is the chair. (He is also chair
of our EMCS TC 5 on High Power EM and chair of our work on IEEE
1642 and 1643.)
The meeting focused this time on the revision of ISO/IEC Guide
107: “Electromagnetic Compatibility - Guide to the Drafting
of EMC Publications”. From the title you can see the importance
of this work in understanding the IEC work on EMC standards and
how our own Society might better interact with the IEC activity
or perhaps follow some of the principles in the document for standards
which broadly apply to many product areas as much of our standards
do. The scope states that the guide procedures should be applied
when preparing a new EMC publication or EMC clauses when revising
existing IEC publications. The document covers emission and immunity
as it describes what basic, generic, product family and product
specific standards are and what each should contain. There is
not enough space in this article to describe all that is in the
document, which is undergoing extensive revision now. When the
revision is available, it will be reported in this column. For
immediate questions, contact the chair, Bill Radasky, at wradasky@aol.com.
In Closing
For now we look forward to another active and challenging year
in developing standards that will serve industry and our members.

Volunteers are always welcome and a variety of tasks are available
for many expertise levels. Have a good year! EMC
