Several others have questioned which standard was being applied. However, when in a situation like what you described, the best way to (hopefully) answer your questions is to state "show me" when the tech tells you "that is the way it is done".
If he / she cannot provide the standard which defines the procedure, call the supervisor, manager, boss, owner, or whoever and get the situation answered to your satisfaction. If not, you may wish to considered packing up your equipment and going home. By the way, does this lab have accreditation to ISO 17025? Regards, John Shinn, P.E.

Ieee. Org Subject: Conducted emissions--green wire? Dear Listers: I recently watched a conducted emissions test. Said test technician connected Line to a LISN, Neutral to a LISN, and ground got stuck in a piece of foam to keep it from touching anything. This bothered me and I questioned this. However, according to said test technician, that is what they are supposed to do. The LISN's and the EUT were put on a metal table surface. The LISN's were well strapped down, but my thing was just sitting there. Doesn't this mean that the impedance of the EUT is some random number depending on the materials and surface finishes of the table, EUT, and where they put the LISN's? The stand I used for the EUT isn't really part of the EUT, just something I had to hold it up. What happens when somebody else mounts a display on a furniture lift and puts it in a piece of wooden furniture?
