FCC Proposes $1,000,000 Fine
On February 16, 2006 the FCC issued a Notice of Apparent Liability
(FCC 06-13) in the amount of $1,000,000 to the importer of
digital audio equipment for marketing such equipment in violation of
Part 15 of the FCC rules. The equipment in question was
subject to, but had not been verified compliant with, FCC Part 15 Class
B
emission requirements. A pdf file of the Notice of Apparent
Liability is
available at http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-06-13A1.
New
Antenna Design Simplified Seminar Offered by Henry Ott Consultants
Why is Henry Ott Consultants (an EMC training and consulting
organization)
offering a course on Antenna Theory? Well, if a product, or PCB,
or cable radiates or is susceptible to electromagnetic energy, it is
acting
as an antenna. Besides, antennas are used in EMC testing, both emission
and susceptibility. In all these cases an understanding of some
basic
antenna theory would be very useful to the engineer or
technician.
However, the way that antenna theory is taught in schools and
universities
- it is too theoretical and abstract to be very helpful. Hence
our
course, Antenna Theory Simplified.
FCC Revises Parts 15 & 18 Rules for
Conducted
Emission
The FCC has revised its rules pertaining to the
amount
of RF energy that a product can conduct back onto the AC power
line.
The Commission amended its rules for Part 15 and Part 18 devices to
make
them consistent with the international CISPR standards with respect to
conducted emission. This change harmonizes the FCC requirements
with
the international CISPR requirements. It should be noted that for
many years Part 15 devices have had the option of complying with either
the FCC limits or the CISPR limits. Now, however, complying with
the CISPR limits will be mandatory for both Part 15 and Part 18 devices.
The ruling was published in the Federal
Register
on July 10, 2002 on pages 45666 to 45671.
The revision applies to all new products
authorized under Parts 15 or 18 of the FCC rules on or after July 12,
2004.
It will apply to all existing products manufactured or imported
on or after July 11, 2005. Equipment authorized, manufactured, or
imported prior to these dates will have the choice of complying with
either
the old or new version of the rules.

European Union EMC
New
EMC Directive (2004/108/EC)
A new updated version of the fifteen year old EMC Directive
(89/336/EEC) was published in the Official Journal of
the European Communities on December 31, 2004 as Directive 2004/108/EC. The new
directives protection requirements remain essentially the same,
however, most other aspects of the
directive have been completely rewritten. See EMC Regulations for more information.
Revised
EMC Directive Standards List
An
updated
list of harmonized standards under the new EMC directive
2004/108/EC (previously 89/336/EMC)
along with their effective dates was published in the Official
Journal
the European Communities (OJ) on December 12, 2006.
The
list replaces all previous lists published in the OJ.
The list is available at: http://europa.eu.int/comm/enterprise/newapproach/standardization/harmstds/reflist/emc.html
