Re: How to fulfill IEC 60601-1-2 EMC Testing Requirements
I would suggest that you discuss the situation with your EMC test house. If you can get them to agree that the changes are very unlikely to influence the EMC behaviour then that may be enough.
What may be possible is to agree, with the test house, that only certain parts of the test programme need to be repeated. So, if you look through your test results and find that, say, the radiated RF immunity was OK but nearly caused problems at 2GHz, horizontal polarization, then just repeat that part of the tests.
How successful this approach would be is somewhat dependent upon how constructively helpful your test house is. They are, naturally, rather conservative but if the approach throughout is one of constructive problem solving (rather than box ticking) can be very helpful.
