I worked on a few products where an attached cord was used for other reasons. The product line had to have a high level of up-time. There was a concern about every connection coming loose. An attached cord removed potential one fault point.

It is possible to design a cord that meets the requirements of North America and Japan. However, as Peter Merguerian noted, it is expensive. The sales volumes of these cords tend to be very low. There are many national differences in most Japanese product standards, and as such, many manufacturers sell different versions of their products in Japan and in North America. Therefore, it typically is cheaper to use cords with only North American or Japanese approvals for the specific sales region. If your product has an attached cord, you can have the product tested to METI DENAN standards including the cord. The cord need not have the PSE mark, but it needs to meet the requirements. Further, you will need to retest if the cord changes in any way. It may be difficult to have the cord vendor keep you updated of any changes that may occur. I have successfully done this on a few products, but it wasn’t a cheap option.

If you wish, e-mail me separately and I can provide you a link (in Japanese) which wil help you find the <PSE> Marked cords of various ratings. There is no national standard in Japan that is harmonized with IEC61010 and the CB Bulletin does not call out Japan. As such no NCB can issue a CB with Japan national deviations. If the invertor is covered by Denan (dc to ac invertors are not covered by Denan) and requires a <PSE> Mark, the invertor can be tested for compliance with Japanese Appedix 8 standard that covers various electrical equipment for safety and emc. If invertor is not covered by Denan and does not require the <PSE> Mark, you can approach a Japanese certification body like TUV Rheinland and they can issue voluntary Japan S Mark approval to IEC61010. Such a cert and Mark will require annual follow-up inspections at the factory --- On Thu, 4/23/09, [email protected] <[email protected]> wrote: From: [email protected] <[email protected]> Subject: Safety: Japan PSE vs UL Power Cords and Japan CB Cert to IEC 1010 To: [email protected] Date: Thursday, April 23, 2009, 1:17 PM Group, ( Sleepless in Japan ) I'm having a hard time finding a standard 120VAC 15 amp, 18 AWG power cord with both the UL and PSE Safety Marks. I've tried several power cord manufacturers and they state this combo does not exist. If so why not???? I have power supplies that are both PSE and UL recognized. Also, I have an inverter that is certified to IEC 1010 with a CB scheme certificate. We need Japan as part of the country deviations listed on the certificate but the Competent Body we chose is unable to list Japan to IEC 1010 on the certificate. Are there any CB's that can provide CB scheme certification for Japan to IEC 1010?
