Additional information

1. Scope

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 25C and a fire point of 340C or greater. This specification applies only to new silicone fluid. Information on in-service maintenance testing is available in appropriate guides.
