While I was at one now defunct computer manufacturer, our safety engineer left for greener pastures in the Persian restaurant business (honest!) and we EMC types were drafted until we could find another one.
However, after I saw the AC decay voltage tester setup I yelled at them a bit, then rewired things so one didn't risk electrocution every them he did that test. It must have been good enough, because various witnessed tests were accepted. This raises the question, however, of whether such a test was done on these computers; it's pretty simple, or can be.
