The regulations require the assumption "that a capacitor manufactured prior to July 2, 1979, and whose PCB concentration is not established, contains 500 ppm PCBs" and is a PCB capacitor. If the date of manufacture is unknown the capacitor must be assumed to be a PCB capacitor and assumed to contain 500 ppm PCBs.
