I would like to clarify a misconception about the CB SCHEME stated in Mr. Juan P. Pena's contribution to the PSTC current conversation. e.g.;
"The CB scheme only works with the "official" organization in every country (UL in USA, VDE in Germany, etc.). For example, all the German TUV's are outside the CB scheme. Are they technically competent? " Most countries have a single test agency that is their "official" organization, but this is not true everywhere. The two countries that were used as an example happen to have more than one. In the United States, there is no single "official" test organization. There are several NRTL's all equal in the eyes of their accrediting body, OSHA. Out of those that are NRTL's, some happen to be NCB's in the CB SCHEME. All equal in the eyes of the IEC. Therefore, there is no official NCB that represents the United States. In addition, Germany does have more than one accredited test house. I can't begin to name them all. However, to set the record straight, both TUV Rheinland and TUV Product service are an accredited NCB of the CB SCHEME. They are both technically competent to do the job they were accredited for. These are my views, and do not necessarily reflect the opinion of my employer. Anton (Tony) J. Nikolassy Factory Mutual Research Corp. Ph: 781-255-4819 Fx: 781-762-9375 Anton (Tony) J.
