Reference EN 60296:2012
Title Fluids for electrotechnical applications - Unused mineral insulating oils for transformers and switchgear
Project Number 23085
Abstract/Scope NEW! IEC 60296:2012 is now available as IEC Standards+ 60296:2012 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60296:2012 is applicable to specifications and test methods for unused mineral insulating oils. It applies to oil intended for use in transformers, switchgear and similar electrical equipment in which oil is required for insulation and heat transfer. This edition includes the following significant technical changes with respect to the previous edition: - specifications for corrosive sulphur compounds that can lead to copper sulphide deposition in transformers (in non-passivated and passivated oils); - definitions of additives in oil; and - re-insertion of a missing note on oxidation.
