CISPR and TC77 Go to Korea!
This year, the Special International Committee on Radio Interference
(CISPR) and Technical Committee 77 of the International Electrotechnical
Commission (IEC) wended their way to Jeju Island just off the
coast of Korea for their annual meeting. About 200 delegates from
20 countries assembled for nine days of meetings to review and
progress standards in these areas:
Subcommittee A: Basic
standards for measurement instrumentation, measurement methods
and statistical applications including measurement uncertainty
Subcommittee B: Standards
for interference relating to industrial, scientific and medical
RF apparatus, to other heavy industrial equipment, to overhead
power lines, to high voltage equipment, and to electric traction
Subcommittee F: Standards
relating to household appliances, tools, lighting equipment
and similar apparatus
Subcommittee I: Standards
for information technology, multimedia, and receiver equipment
Subcommittee H: Basic
standard for limits for protection of radio services
In addition to the usual CISPR meeting
schedule, this year TC77 (Electromagnetic Compatibility) also
met during the second week. TC77, for example, sponsors the IEC
61000-4-X series of standards, which includes the most commonly
used immunity testing standards. Their subcommittees include:
Standards for low frequency phenomena
Standards for high frequency phenomena
Standards for high power transient phenomena
The connection with CISPR involves joint
projects, which at the present time include the following topics:
TEM test methods
Use of reverberation
testing (IEC 61000-4-21)
for both radiated emission and immunity testing
Measurements in fully
absorber lined rooms (FARs)
A myriad of work was conducted on topics
ranging from extensive work on measurement methods, site validation,
and limits above 1 GHz to preparing the next revisions of the
immunity test procedures. More detail on the activity will be
addressed in reports provided to the EMC Society Standards Advisory
and Coordination Committee (SACCom).
Included with this article are a few photos
of the meeting, which was held at the Lotte Hotel. The host of
the meeting, the Korean Agency for Technology and Standards, Ministry
of Commerce, Industry and Energy, Republic of Korea, selected
this hotel. The Korea Testing Laboratory in Seoul, Korea organized
the meeting. The facilities and organizational support were superb.
We thank the host and organizers. Finally, we hope you enjoy the

that a pig is in the background; apparently, they had pork
on the mind!

The article in the Spring 2003 issue
of the Newsletter on Changes to ANSI C63.4 from
the 2001 edition to the 2003 edition misstated the date
in the first paragraph. This showed 1991 instead of 2001
for the edition of the standard, which is being replaced
with the 2003 edition. We hope that this has not caused
any confusion and it was clear in the rest of the article
that the comparison was between the most recent two editions,
not one dating way back to 1991.
