Polychlorinated Biphenyls (PCB) Content
Standard Test Method for Analysis of Polychlorinated Biphenyls in Insulating Liquids by Gas Chromatography, ASTM D4059
Polychlorinated biphenyls (PCBs) content in insulating liquids is a test of a chemical property. It is done primarily for purposes of complying with various environmental and regulatory requirements governing management of PCBs. New oil should be “none detected” for PCBs – the detection limit is typically specified as 2 ppm, so ND is less than this value. In-service equipment and equipment for disposal is frequently regulated according to the insulating fluid’s PCBs content. Of the many PCBs analysis methods, ASTM D4059 is the most useful for measuring PCB content in electrical equipment in the United States.
