Dear Doug, AFAIK, If the product type is not listed in CCC List. CCC Mark is not required. This is the mandatory requirement. If I understand you correctly, you mean if it is not tested, you may feel uncertain whether it will get into trouble in China. If this is the case, you may apply for

First convert the limit in Volts to micro Volts, then simply take the log of that number and multiply by 20. Example: 1) to convert 1 Volt into dBuV 2) 1 Volt = 1,000,000uV 3) 20log 1,000,000 = 120dBuV To convert dBuv into Volts just work backwards. Divide 120(dBuV) by 20 (= 6) and take the

Hi The harmonics limits haven't changed. The method of applying the limits has changed slightly, but if anything they're easier to meet now than they were before, so its a reasonable assumption that your EUT is OK. Steve Seller - York EMC Services On 12 Feb 04, at 12:42, Colgan,
