Not a legalese answer but a technical consideration. RE are measured only
above 30 MHz due to measurement accuracy concerns at lower frequencies. The
CE limit, in addition to preserving power quality in radio frequency bands,
also limits RE from long power lines. So there is a good technical
Robert,
Yes of course! e.g. For entered 1 minute, timer expects 60, (3600 cycles),
Second Ticks but on 50 Hz power receives only 50. Therefore cooks for
another 10 ticks which takes 1/5 minute longer.
Thank you for the correction.

I would like to express my thanks to all of you who provided me with
valuable information on this topic. I now have a good understanding of the
possible risks associated with such an endeavor.

Ron, my understanding is that if these products were placed in distribution
- e.g., not under your control - they can remain there for a virtually
unlimited time until sold as is. However, if the products are still in a
warehouse under your control, then you have two options:
1. Ensure that
Hello all,
Is there any new requirement on doing conducted emissions testing on
distributed DC inside a building.
RE: EN 55022:1998
The DC comes from an AC - DC supply (compliant).
Would there be a cable length above which the conducted test must be done?
I know some immunity tests are required
Hello to all,
This is directed to all the EMC Directive experts on this list. I need your
help.
It has just come to my knowledge that a sizable quantity lot of finshed ITE
products have been built
and being stored in a warehouse. These products, facing obsolesence, are 100%
compliant with
Thanks to everyone that responded. A critical clue was to look at the plugs
separate from the power cords, and work backwards. I think I can figure it
out.
Again many thanks to those who took the time to respond. I appreciate it.

On second thought, to be a little clearer, the CB scheme may have nothing to do
with this, but the scope of the question includes references to voltage ranges,
voltage surges, dips and interrupts, ripple and anything that may be a
requirement specific to Japan?

When in doubt try http://www.panelcomponents.com/guide.htm I have to admit
that it is confusing with the US plug specified for 220 volt applications.

Can someone direct me to the reference's) that would lead me to a description
of the Japanese voltage requirements for safety in CB Scheme.

Gary,
The best specifications that I have found are:
* South Korea 220V +/-10%, 60Hz +/-4%.
* North Korea 220V +6.8% -13.6%, 60Hz +0.0% -5.0%.
We use linecords with Schuko (CEE7 VII) plugs for both countries.
South Korea changed from a 110V 60Hz standard a few years ago. For several
years

I would think the clock timing and microprocessor timing would suffer and as
a result it may deliver heat but programming prarameters could be
drastically incorrect.
For short periods of time the heating effects would be minimal but who knows
what a safe time period would be. Better to have
