Donald At the risk of pre-empting others with more time to give a comprehensive answer, within Europe this type of product would fall under the General Product Safety Directive 92/59/EEC http://europa.eu.int/eur-lex/en/lif/dat/1992/en_392L0059.html
Currently this is rather vague on applicable standards, but I believe that it is in process of being amended to be harmonised standards-based directive like the LVD, R&TTE Directives etc. This amendment may (already have been?)be passed this year to come into operation in 2003. As such, you would generally apply the same safety standard that would apply if the product were actually mains powered, e.g. EN60950 or EN60065. Obviously the requirements for the AC mains circuits would not apply but - in particular - the flammability requirements would be very applicable. In practice - and even if the new text is still vague - I have always thought that there was very little obvious alternative anyway - especially in countries like the UK where a "due dilegence" defence in law in necessary.

I have been asked to determine what compliance standards will have to be applied to ensure that the product meets regulator compliance requirements. The appropriate EMC standards are quite straight forward but I am having more difficult nailing down product safety requirements. The product being supplied via an external low voltage ( <20V DC @ 6A ) appears to technically fall outside the scope of both the European LVD directive and North American NRTL certification requirements for products directly connected to the public mains. The product is similar to that of a laptop computer running from an wall mounted adapter. Questions have been raised regarding flammability of enclosure materials which will have a significant impact of the products cost. Could any member of the forum who may have had to address similar situation share there thoughts? At this point it would appear that provided we ensure the external power supply conforms to any applicable safety standards in which the equipment is to be marketed that their is no legislated (hate to use this term) requirements to safety certify the table top product.
