Hi Grace – CNS13439 requires a 3m test to prove compliance. Do you know if this will be an issue for the BSMI?

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.

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.

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.
