No, or probably no. See my response
Every person working in the EMC field has their own techniques when dealing will
emissions issues. Mostly based on past experiences, product type, what tools
they have handy or can afford plus the political atmosphere where they work.
I am no exception, part of my list of tools include:

Article 7 in the Directive discusses using national standards to meet the

Partially Wrong.
The only reference you will have to use in Europe
with the Compliance matters and standards is the

Dates (DoW) printed in the standard itself may

The reason for this is that standard

In a conversation with an acquaintance of mine, the EMC Directive became a

Your subject states "Taiwan and China approvals" but your message specifies
"Korea and China approvals". I asume it's Korea and China that you ar4e
interested in.
TUV Rheinland of North America is very helpful in obtaining approvals in the

At minimum you really should have a spectrum analyzer, but
that's my opinion.
For a good 'homemade' probe try Doug Smith's web site.

Dear Brian,
The Canadian Standard CAN/CSA -C22.2 No.0.17 -92 offers within the Appendix
D a so called "Flame Tests Equivalency Table" that gives the information for
which you are looking for.
If you want, give me your Fax number and I will fax it to your attention.
Respectfully yours,

But do note that the Part 15 revision of July 2002 does add radar detectors
as an exception to the 960 MHz limit.

Some things are not so obivious, take the case of that of VSAT (very small
aperture satellite terminals ) receivers and that of radar detectors.
That's when an unintentional source should be mixed with the LO and
