LIQUID DIELECTRICS
**************************************************************************
NOTE: Select 2 ppm for Air Force projects.
**************************************************************************
Liquid dielectrics for transformers, capacitors, reclosers, and other
liquid-filled electrical equipment shall be non-polychlorinated biphenyl
(PCB) mineral-oil or less-flammable liquid as specified. Nonflammable
fluids shall not be used. Tetrachloroethylene (perchloroethylene) and 1,
2, 4 trichlorobenzene fluids shall not be used. Liquid dielectrics in
retrofitted equipment shall be certified by the manufacturer as having less
than [50] [2] parts per million (ppm) PCB content. In lieu of the
manufacturer's certification, the Contractor may submit a test sample of
the dielectric in accordance with ASTM D 923 and have tests performed per
ASTM D 4059 at a testing facility approved by the Contracting Officer.
Equipment with test results indicating PCB level exceeding [50] [2] ppm
shall be replaced.
