Greetings All,
Many members have expressed their concerns in regard to the maximum permissive
limits for hazardous substances set by China. Thanks to Michael Kirschner of
Design Chain Associates' help, I put together the following information for
your reference.

Sorry for all this non-safety non-EMC stuff but here's another
environmental compliance question, regarding WEEE and the
crossed-out-wheelie-bin symbol and bundled accessories.
Suppose a product ships with an accessory. Do both the product and the
accessory require the WEEE symbol, or can the

Does the IMO requirement MSC/Circ.862 apply for US Coast Guard approval?

Singapore Airlines offers it, too. I used it last month on a flight
from San Francisco to Hong Kong. Worked well for me, too.

Many of the product family standards (PFS) call out their own level and
duration of voltage dip or interrupt using the testing techniques of
61000-4-11.
(61326-1: 1/2 cycle 100%; CISPR 24, Table 4)
This has been a topic of discussion around here, what effect on compliance

Doug,
A short time ago I used the wireless setup on a Lufthansa flite from
Germany to the US. It was easy to get into, the setup was convenient (they
took my credit card number right away), and the service was good.
One of the things I did was call my daughter on my VoIP connexion to
But what product family standard are you using that calls out this test
method? If it is CISPR 24 (and EN 55024) this change doesn’t matter as
CISPR 24 uses dated references for the test methods. Check your product
family standard to see if the same happens there.

This specification IEC 61000-4-11:2004 has been published as of 3/1/05 and the
DOW (Date of Withdrawal) is 6/1/2007. It is this version of the standard that
the new 80% dip level has been introduced.

I got a Voltage dips / sags / interrupts question .
Is there a new amendment to IEC 61000-4-11 where in one of the test criteria
drop out is 80 % with 25 cycles , when does it become effective ?

I agree. It is not a matter of We cannot sell because it is not CE
marked, it is a matter of the fact that you do not know what affect the
antenna will have on a unit that it has not been tested with.

All,
What is your opinion: Do the microprocessor system destined for education
(8051 microcontroller programming) falls under WEEE and ROHS ?
The system is made that way, that you see its education destination at once,
and it is really unusable for other purposes.

Dear all,
EMC
Is the antenna active? Is it passive? It IS fed with electrical energy - so I
think active although not in the usual sense.
Can it's construction modify the signal that is fed into it? Maybe - it could
have dissimilar metals that, during its life, corrode and form a diode. I
could
