Plastic Sheeting
Welded or overlap joints in PVC sheets can be tested for defects by using a DC Holiday Detector or a high voltage AC Spark Tester.
Spark Testers provide an inexpensive means of testing but have no output voltage meter or audible alarm. However, they can test joints even if the backing is not connected.
