Thank you all for your comments and advice, it is appreciated.
For your interest, the product had gone through approval and though there were some ESD induced abnormalities these were considered a low risk. It was the reports from two independent customers regarding a particular failure mode that led to this investigation. To achieve this particular failure mode we had to reduce the level to -800V ; I should point out that at higher levels, other failures were infrequent. What is probably more 'interesting' is that both customer's method of use was different, though valid, to the way we had perceived. As an aside, when working on compliance problems I am often reminded of the following: "When looking for the light at the end of the tunnel, make sure you are not in a cave" Thanks again, Vic Gibling Compliance Engineer (in the making) Marconi Applied Technologies ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
