IEC 60666 Detection and determination of pasivants in mineral insulating oils
It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. The main changes with respect to the previous edition are listed below: Antioxidants and passivators are frequently added to mineral oils to enhance oxidation stability and reduce the 66066 charging tendency, respectively.
Since existing standard test methods only allow analysis of individual additives, new approaches are needed for the detection of mixtures.
