RE>>Part 68 and PCMCIA Voltages 11/20/96
If we are talking about test voltages for electric strength tests, I don't about part 68, but, in CSA C22.2 No.950 or UL1950 equivalent, it states that the test voltage is determined by what the working voltage is & the type of insulation used. (5.3.2) Test voltages can be from 1000 V to 10,607 V pending.
