Thank you all for your valuable replies. I've always tended to be conservative when writing test plans. These days, however, everyone is trying to pinch every penny. I agree that these tests are not terribly expensive as EMC testing goes. But then, expensive that is a relevant term.
This is a computing device with a display and is primarily intended for use within industrial process control applications. Power interface is via a field-wired terminal block. It is designed for panel mounting because most often it is likely to be included in the same enclosure as a PLC. So you can see that the primary intention is clearly industrial. However, as market pressures have driven the price of such devices down they have also been adapted to many other types of applications - even car washes. The device isn't marketed toward such applications, but obviously system integrators can and will do what they choose. I agree with John with regard to manufacturers statements and rely upon them heavily for both EMC and safety compliance. However, John's reference to the acceptance of such statements on the part of regulatory authorities are really the bottom line and I don't think that one can rely upon what I\we may consider to be common sense.

I see within the Scope of EN 61000-3-2 and -3 that those standards should apply to devices which are connected to 'public low-voltage distribution systems'. Are panel-mount type devices intended for use in industrial applications generally exempt from those standards due to this clause? What do you mean by a 'panel-mount device' If it isn't a finished product, but something like a meter or switch, then it's a component and the standards do not apply to components. If it is a finished product, clearly unsuitable for operation from the public supply, or if the manufacturer specifies that it is NOT INTENDED to be used on the public supply, preferably with an explanation that it does (or may) not meet the required standards, then the standards do not apply. We don't have any certainty that a manufacturer's statement would be accepted by every regulatory authority, even though it should be. The responsibility for using such a product on the public supply in defiance of instructions must rest with the user. -- OOO - Own Opinions Only.
