1.1 This specification covers silicone fluid for use in transformers, capacitors, and electronic assemblies as an insulating or cooling medium, or both. 1.2 Silicone fluid covered by this
specification is polydimethylsiloxane having a nominal viscosity of
50 cSt at 25°C and a fire point of 340°C or greater. This
specification applies only to new silicone fluid. Information on
in-service maintenance testing is available in appropriate
guides.
