Re: Electrical Safety regulations regarding PLUGS for DIRECT PLUG-IN TRANSGFORMERS in CHINA
Constantin, The implementation rule, governing CCC approval process, for the standards Ted pointed out is CNCA-01C-003. An English version of this implementation rule is available from the CNCA web site at www.cnca.gov.cn. Click ENGLISH (upper right corner) to go to English web page. The CQC (merged with CEMC) is the only CCC certification center for the scope of this rule. There are about 20 test labs which are the best resources to ask questions if you have any connection to the people speaks Chinese. A quick Google search for the picture turned out at http://www.interpower.com/ic/sbc-x.asp. Two of my Chinese colleagues confirms this is the type they use in China. In addition to this type (two poles with ground), "two poles (two parallel plates, equal length)" and ""two poles dual use (two round pins, I believe)" are the types listed in the GB 1002-1996. This standard in Chinese is available from webstore.ansi.org. The cost is less than a dinner bill. The standard provides diagrams and dimensions. It should not be difficult to figure out dimensions (in numbers). For a product under 36V, CCC may not apply. From my understanding, 36V applies to input and output, not only output. If a product interested is a power adaptor, other implementaion rule(s) and standards may apply. For a power adaptor for IT equipment, implementation rule CNCA-01C-020 applies. Test standards are GB4943, GB9254, and GB17625.1. For a power adaptor for audio/video equipment, implementation rule CNCA-01C-017 applies. Test standards are GB8898, GB13837, and GB17625.1. I hope this helps. Regards, Grace On 5/5/08, Ted Eckert wrote: The most common grounded plug type in China is the flat plug similar to the Australian plug.

If I understand the original question correctly, this is what it really comes down to. The power supply may be Listed by itself, but that does not mean that the end product using it is then somehow covered by the power supply Listing, even if no additional hazards are present in the end product outside the power supply. If there is a requirement for the end product to be Listed, then it must be evaluated separately. Allowing the power supply Listing mark to be visible in the end product in such a way that the customer is led to believe that this mark covers the end product is a no-no.
