Hi Jim, As the function of the Emission standard is to protect the spectrum, it cannot be seen different then "protecting the spectrum of the environment the equipment is used in" (office). (seen the physical range any interfence can go: +/- 30 meters) Then seek appropriate standards, taking account:
- it's function, - the essential requirements of any applicable directive, and the - the essential phenomena (due diligence) as defined by the EC. Then the choice can be made easily: the environment is office, seeking compliant emission standard is EN 55022 the equipment is motor operated EN 55014, was meant for that; is there any emission aspect that can be overlooked using EN 55022 ? One difference is click, but EN 55022 is mere severe in this aspect (no relaxation) essential requirements: one shall not interfere : the extended frequency measuring range fits better to the requirement. The fact that a radiated instead of a conducted measurement is made ; is more close to the essential requirement. For test phenomena both are equal (but for the F-range) Then the choice for immunity should follow the same logic.

The only electrical port on the machine is for an AC mains input cable. There is no interface port. There is a control panel and circuitry that controls the motors and positioning of mechanisms to accomodate different styles of folds and for adjustment for different sizes of paper and envelopes. The product is typically used in an office environment as the folding and inserting functions are generally for mail preparation. I believe that the appropriate EMC standards for the above and similar types of electromechanical equipment are EN 55014-1, EN 55014-2, EN 61000-3-2, and EN 61000-3-3. The choice of EN 55014-1 and EN 55014-2 is based on the product's main function being motor controlled mechanical operations. I don't see how this type of product fits into the scope of EN 55022 and EN 55024 for ITE if I read the scope of those standards and the definition of ITE. However, I have heard different opinions from some very reputable authorities in Europe who feel that EN 55022 and EN 55024 can be appropriately applied to this type of product based, presumably, on its intended operating environment. The opinion seems to be that EN 55014-1 and EN 55014-2 really only apply to household appliances, although in MY reading of the scope (not just the title) it applies to more types of equipment than that. Bottom line: What standards would you apply and why? Thank you.
