I am lucky to have extraordinarily resistant enamel on my teeth, and have to visit the dentist only at intervals of many years, in spite of being encouraged by them to do so every six months. > >It is the difference between good and bad test houses >to help selecting test suites for unknowing customers >(!??!) that other otherwise choose for >short time gains and long time losses.

I don't agree, not because you are necessarily wrong but because many larger companies themselves don't agree. Yes, my interests lie mostly with SMEs, but I have advised very large companies and they are by no means complacent about testing costs. >Costs for EMC serial production >etc. are neglect able if designed in, from the start. This is true for *large volume products*, like TV sets. But it is not applicable to a large company that makes, for example, a very wide range of professional-use products, each of which is made in quantities not exceeding 1000 or so. >The gain from compliant equipment in terms of quality, >product life time and need for service can easily >be much higher then all testing suites I can imagine. I don't see how EMC conformity affects 'quality', life time and need for service. > >And there is much more to test than only EMC ! Of curse, safety has to be included, and safety conformity MAY affect 'quality' and 'need for service'. Product life-time is mostly determined by market forces (fashion and/or new versions of Windows) rather than technical end-of-life. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
