Principally it's the function of the equipment that determines the standard to be used. You should read the title and scope of each standard harmonized to select the most suitable.
Secondly, an equipment containing technologies borrowed from another category (say refrigerator with a internet connection), should at least be thoroughly evaluated against the risks that may result if testing to the other standard be not carried out. This is what is called out the emc assessment in the directives text. After all you should comply with essential requirements and not with a standard only. For those standards that keep up with technology , complying to the standard will most often be sufficient. However there are some standard committees that are obsolete in following technology developments (not in validity). Using them without due diligence regarding the sense of the directive may result in non compliance with the essential requirements. More and more standards contain clauses about multifunction equipments that should comply with all applicable standards. Piotr, in your case there is a specific standard for access control systems (EN 50133) referring to EN 50130-4 for immunity (I believe, did not check) and EN 55022 for emissions. Regards, Ing.

In access control system you can find all of: "entry, storage, display, retrieval, transmission, processing, switching, or control, of data" and it is "equipped with one or more terminal ports typically operated for information transfer". I was sure I should test such system devices to EN55022 and EN55024. Should I look for standards for keys and door locks ?
