What specifications are listed in a Shell transformer oil data sheet?

A Shell transformer oil data sheet, for a product line such as Shell Diala, typically lists compliance claims, intended service, and typical property ranges. Common properties include density, viscosity, flash point, pour point, acidity, dielectric dissipation factor, resistivity, and breakdown voltage values based on referenced test methods. It may also indicate whether the oil is inhibited or uninhibited and provide guidance on handling and storage. For mineral insulating oils used in transformers, many data sheets align property targets with IEC 60296 requirements for unused mineral insulating oils.
