Hi Leslie, some answers: Is this called compliance testing or engineering verification?" Anything that has to do with product quality (like EMI) needs to be addressed in terms of engineering.
"Can we do this and declare compliance?" Sure you can declare compliance, as the European System is simply not targeted to complying with standards, but to complying with "essential requirements". Of course you cannot declare compliance with the standard (to the letter). Using standards is just a way to presumption of compliance. Art 10.1 EMCD If you really DO deviate from the standard , you will need to follow the TCF route using a Competent Body to show compliance. Art 10.2 EMCD Any deviation of the standard is doomed to art 10.2 , but changing an undefined dwell time to better meet the intention of the standard won't lead to a law suite. Several product type of standards do address the topic of dwell time btw. One never can get condamned by not following the prescriptions of the EMCD or standard, only by creating to much EMI or lacking susceptability (and other essential phenomenae).
