That is the preferred method for Mil-810 testing. The rational is that they would like this thing to work within its actual environment not as a lab queen, I have not seen it required in commercial work. In my opinion it is one of the reasons that major manufacturer's like Dell and others often fail after a few shipping cycles between labs, or even after sitting around for a while. They are designed not for EMC robust but to be quickly manufactured and easily opened to have upgrades added etc. All of this fights against the enclosure retaining its shielding effectiveness. I'm sure many of us have spent time cleaning seams, gaskets, and blank panels, and other mating surfaces because of all the shipping vibration etc. If none of you have then neither have I :) Gary -----Original Message----- From: John Woodgate [mailto:[email protected]] Sent: Tuesday, October 04, 2016 8:47 AM To: [email protected] Subject: [EXTERNAL] Re: [PSES] When is EMI testing performed? No personal experience, but I have heard of this procedure. It might also apply to safety testing. Logically, EMC and safety testing won't affect the environmental test results, but the opposite is not so very improbable. With best wishes DESIGN IT IN!

Have any of you ever seen EMI qualification intentionally scheduled at the end of environmental qualification for the purpose of assessing EMI performance after the suite of environmental tests has taken its toll?
