The garment is placed on a highly insulative surface (such as our ShockStop 207 AS insulative switchboard matting) and the resistance from sleeve to sleeve is pegged by the megger but take notice, while this testing seems simple it can post sporadic results, especially if the garment is testing to the high end of the electrical resistance range (>1.0E10 for example). Why? Testing to high resistance values accurately relies on following TR-53 precisely AND using test equipment and leads that have an extremely high degree of electrical insulation.

To test the insulative capabilities of your equipment simply place the equipment and leads on a highly insulative surface such as Lexan or clean dry glass. Cross the leads over one another, send a charge through the cables and peg the results. With much of today's test equipment this may register <1.0E10> as the current goes through the insulation of the cables and reads on the megger (incidentally this reading would allow the garment to pass when in actuality it may be failing). To help with obtaining accurate results know your equipment's true limitations. Don't cross leads and utilize the optional equipment grounds if provided.
