Gentlepersons: I have just been advised by an NCB that I can not obtain a single CB Scheme Certificate and Test Report for a product that has both ac and dc electrical ratings. This is supposedly based on IECEE Decision 1D107. I asked for a copy of this document and was advised that a copy could not be provided, because IECEE Decisions are, "for NCBs only."
Can anyone out there provide me with a copy? These kinds of decisions are likely found on the IECEE and CB Scheme web sites, but are password protected "for members only." It is my view that I need to study this document to see just how far reaching the implications are and to properly advise my customers of its impact on them. This decision will affect all products with optional dc-dc converters for use as backup/redundant power supplies and products that swap out ac-dc for dc-dc converters in the factory. It may apply to other scenarios. While I have not been hit with the full force of this yet, I expect to be in the not too distant future. So will many of you. Herein lies the rub: IECEE 02, Scheme of the IECEE for Mutual Recognition of Test Certificates for Electrical Equipment (CB Scheme) Rules of Procedure (copy available from www.cbscheme.org), clearly indicates in Subclause 4.2.1 that the CB Certificate is the tradable good (my terminology) and that a Certificate is only valid when accompanied by a Test Report. So, if I am required to have a separate Certificate for an alternate set of electrical ratings or when there is a redundant/backup power supply in a piece of equipment, I will also be required to obtain *a*second*Report*. It has not been made clear to me whether this second report will have to be a complete report or might be in an amendment, or if two independent certificates can point to a single test report as the basis of the validity of both, but the subtleties of this imply that a COMPLETE REPORT will be necessary to support each Certificate. $£¥KACHING!!! I recommend to this body that each of us pull out our rapiers and lobby long and hard through each industry trade association, e-mail list and directly with all NCBs, CBTLs or what have you, to get, what is on the face of it, this ridiculous and costly decision rescinded. I am asking for this item to be added to the TIA TR41.7 and TR41.7.1 meeting agendas, for next month's quarterly meeting. There is still value in obtaining a CB Scheme Certificate and Test Report, though now that value has been taken down a notch. Regards, Peter L.
