1.1This specification covers silicone liquid for use in transformers, capacitors, and electronic assemblies as an insulating or cooling medium, or both.
1.2Silicone liquid covered by this specification is polydimethylsiloxane having a nominal viscosity of 50 mm2/s at 25°C and a fire point of 340°C or greater. This specification applies only to new silicone liquid. Information on in-service maintenance testing is available in appropriate guides.2
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
