IEC 61000-3-2 and 3-3

2000-07-15 Thread Alan E Hutley
Ladies and Gentlemen

If you are interested in the situation on 61000-3-2 /3-3 you might like to read 
two articles on our web site
Harmonic Current Standards...the end of the line and EMCTLA Meeting Report.  
For those that are not aware the EMCTLA is the UK association of Test Labs.   
at the meeting was Maarten Vrolijk from Phillips who is the chairman of the 
CENELEC TC 210 committee.
www.emc-journal.co.uk just click EMC+Compliance Journal and it will take you 
direct to the articles.

Any problems let me know and I can email you them direct.

Re: Internet port in test equipment

2000-07-15 Thread Barry Ma

Hi,

Eric Lifsey explains to me in a separate Email today: "On page 11 (of EN61326), 
at the top, the first paragraph seems to be clear about the exception for I/O 
ports that employ shielded cables.  It overrides any discussion of shielded 
cables in -4-6."

Please allow me to quote the paragraph of EN61326 here:
"For I/O circuits where the manufacturer specifies that shielded cables must be 
used... the conducted immunity requirements can be omitted within the frequency 
range 150 KHz to 80 MHz."

This is a convincing argument. Therefore EN61326 exempts 1000-4-6 from I/O 
ports with shielded cables. Thanks Eric.


Regards,
Barry Ma

That's right Dale. CETCOM in Saarbruecken offers these service for all the
relevant the EU countries. 
Contact the person under cc for more information.

CAUTION!  The Notified Body is not optional.  The ISM band is not
harmonized.  The transmitter is a class 2 product and member countries may
have restrictions.  Further, the EC authority of each memeber country must
be notified 4 weeks prior to placing on the market and a fee of $500 is
required.  Contacting a NB is good advice.

Dale.

The ETSI standard you refer to is actually ETS 300 328, and you can retrieve
a copy from www.etsi.org

Your transmitter module would certainly fall under the scope of the R&TTE
Directive. I would contact a European notified body, and pay them to tell
you which standards you need to meet. Then, test to those standards, which
are likely to include radio performance and EMC and safety. Then, have them
assess the test reports for compliance to the R&TTE Directive. FInally, you
can then declare conformity to the applicable directive, and that you meet
"all essential requirements" and put the CE Mark on the product and sell it
in the EU.

If you have never been through this (and because the R&TTE is new as of
April most people have not) it pays to get a Notified Body and test lab
helping you along.

Mr. Woods informed me of missing data from my first e-mail - sorry about
that!

Equipment is medical (EN60601-1 Safety, EN60601-1-2 EMI)
Countries: USA, Canada and Europe at this time
There is also an option to use a short range telemetry unit with this device
to transmit patient data. It is spread spectrum at 2.4 GHz. Is an OEM
configuration which we repackage (the transmitter) into the battery back
(+12V) worn my the athlete/patient. It does not have CE, but is complaint
with ETSI 300.28 (I'm not sure what this is it yet)and FCC (which I still
have not seen any FCC cert. yet). Does the telemetry module fall under the
scope of the RTTE directive?   
If I'm missing any other pertinent information please advise.
Thank you

Good Day Forum Members
I have a very similar question that Barry Ma presented on 7-13. It
regarded
a Ethernet port on test equipment. His question was as follows:
 
1. A phone line port has to comply with related regulations in
Telecom
world. In my recollection, PC industry just added an Immunity
requirement to
the phone line port. (It is included in EN55024?) But Ethernet can
be
converted to phone line through an adapter. Is there a similar
immunity
requirement for the Ethernet port in test equipment? If not, should
it be
added to EN61326?

My dilemma is that my company "inherited" a piece of equipment via
an
earlier acquisition. On this piece of equipment they incorporated an
RJ-11
telecom jack. Over this jack they are running power (+12V & pwr gnd)
from a
remote battery pack and RS-232 (Tx & Rx)comm which terminates to a
PC. Can
anyone provide me with some insight with regards to EMI/RFI
requirements and
device safety (I have somewhat of a handle on the safety side - but
welcome
other opinions!). None of these four lines have any type of safety
(over
current/voltage) protection nor any EMI filtering, etc. If you can
provide
some insight or reference to required standards I would appreciate
it

Thank You (in advance)
