David, Tim, and Others:
It is still an issue in Taiwan. BSMI do not feel comfortable to accept 3m
data due to the near field concern. If CISPR 22 (or its replacement)
committee explicitly accepts 3m data, BSMI will accept 3m data.

Tim,
I know that this has been an issue in Taiwan in the past - I had a
submission rejected a few years ago for this reason.
I'll defer to someone with more recent experience with Korea since the
regulating agencies just changed there - the last approval I completed there
was at my last job just before the change occurred (now I'm realizing that I
haven't sought approval for a non radio device for a long time in Korea so
there's another reason to defer to someone else).
As for 1-4, for most devices, you're dealing with self-declaration or
its
equivalent. This is up to you to determine if your results indicate
compliance in a 10m chamber since a 10m chamber is the common reference
indicated in most emissions standards. Taking the assumption you state into
account, you should be in good condition. It would be a good idea to obtain
some correllational data to a 10m chamber to confirm you're getting similar
results (and use some engineering judgement in the near field).
This is a short response to a complex issue, but I hope it was somewhat
helpful.
Best Regards,
-Dave

Subject: 5 Meter Chamber For EMI Qualification Testing
Hello Group,
I would like to know if radiated emission test data taken at a 3 meter
distance in a 5 meter semi-anechoic chamber is valid for qualification testing
for the following:
Please assume that the chamber is fully validated with volumetric NSA.
1. FCC/Industry Canada
2. VCCI (Japan)
3. Australia/New Zealand
4. Europe
5. Taiwan
6. Korea
I ask this question because I have been hearing that some countries do
not
accept 3 meter chamber data.
Thanks for your help.
Tim Pierce
