Barry brings up a good point. The products manufactured by my company, Evans & Sutherland, are typically high computer systems (flight simulators) used in a Heavy Industrial environments. As such we routinely test to EN 55022 Class A (emissions) and EN 50082-2 (immunity). More recently we have also added EN 55024 (ITE immunity) as well. Depending on the end use application, some of our lower end image generators do not have heavy industrial immunity but they are all Class A devices. These are not used in residential applications but rather as light industrial products.

You said: "I believe its because the scope of EN 55024 is geared toward the residential, commercial and light industrial environment. If I were producing a piece of ITE equipment intended for a truly industrial environment, I would consider Class A emissions (yes Class A) from EN 55022 (assuming it's ITE). I would then look for the best fit of an immunity standard for industrial environments. Either a generic immunity standard such as EN 50082-2 or another whose scope is directed at an industrial environment." I respect the due diligence to find a best-fit immunity standard for industrial environment, especially when customers want to do so. Please allow me to ask a question when customer don't care: Is there any conflict with written statement in relevant standards if we simply follow EN55024 for ITE used in industrial environment? Thanks.
