TUV does have a mechanism, they issues the GS mark for products and the Bauart mark for components. Dave Clement Motorola Inc. Test Lab Services Homologation Engineering 20 Cabot Blvd. Mansfield, MA 02048

Why would a mfr get a UL recognition approval for a commercial ITE style single phase 155-230vac computer style product but for that same product get the TUV "GS" mark? Mfr is a stateside company. Product to be used in restricted areas with trained personnel only. But, one that essentially anyone could buy. What's the advantage of getting such a mixed set of approvals? <<<<<<<<<<<< It's not really a mixed set of approvals. UL must have considered the device to be incomplete in some way (does it have an enclosure?), therefore they Recognized it as a component as opposed to Listing it as a finished product. The GS Mark has no mechanism for delineating between components and finished products - both can receive GS approval. Hence the TUV GS mark. That's my guess, based on the limited information you gave. Greg Galluccio www.productapprovals.com
