PCB warning label on a power transformer known to contain PCBs. A polychlorinated biphenyl (PCB) is an organic chlorine compound with the formula
2.2 Identification of PCB Transformers 2.3 PCB-Contaminated Mineral Oil Transformers 2.4 Identification of PCB Capacitors 2.5 Labelling of PCB Equipment 2.1 Introduction In this handbook, PCB equipment means electrical equipment that was designed to use PCBs. PCB equipment includes PCB transformers and PCB capacitors. PCB Congeners A PCB congener is any single, unique well-defined chemical compound in the PCB category. The name of a congener specifies the total number of chlorine substituents, and the position of each chlorine.
Orange PCB Label The orange PCB label with white printing identifies PCB-contaminated transformers. This category of contamination indicates that the dielectric fluid contains between 50 and 500 ppm PCBs. The concentration is lowered into this range by retroflushing, which is done and certified by a qualified contractor. No PCB Label Required
Tcb Store It New Label Grey Bg And in reality, it's not far off from what some do when leaking transformers are transported or stored than action level for polychlorinated biphenyls — or PCBs — but many of the transformers are This article summarizes the various types of printed circuit boards, the typical to the terminals, as were the wires from the larger devices, such as transformers. and a silkscreen coating may be added as a final layer to label th English and Chinese, together with a chemical waste label as detailed in Appendix B. ▫ Unwanted PCB transformers, if still in good physical condition, should If the ballast does not say "NO PCBs" on the label, the ballasts may contain PCBs .

PCB mount transformer consists of metal core, an outer casing, mounting brackets and connecting terminals. PCB mount transformer is usually made of light materials so that they can be mounted on a computer board or over a chassis. The transformers are usually manufactured using semiconductor fabrication technology. PCB mounted transformers are
Look for old Environment Canada labels that state "Attention PCB" or other labels stating that the equipment contains PCB. Transformers may contain PCB liquids, PCB-contaminated mineral oil or mineral oil. If in doubt, sample and analyze.

Makes jack easier to use with breadboards, and labels the connections to cut down on confusion about the 6.3mm jack chassis/PCB stereo switching JP-611.
Since sampling the PCB All transformers require registration with EHS and labeling with PCB level. Note:PCB-contaminated transformers with ≥50 but less than <500 ppm PCBs do not require the yellow PCB label, but must still be labeled with PCB ppm content. All PCB transformers should have already been drained, retrofilled with non-PCB mineral oil and tested, Transformer test methods.
