DESCRIPTION

BS EN 62021-2:2007


This standard BS EN 62021-2:2007 Insulating liquids. Determination of acidity is classified in these ICS categories:
  • 29.040.10 Insulating oils
Describes a procedure for determination of the acidity of unused and used electrical mineral insulating oils. The method may be used to indicate relative changes that occur in a mineral insulating oil during use under oxidizing conditions that may or may not be shown by other properties of the resulting mineral oil. The acidity can be used in the quality control of unused mineral oil. As a variety of oxidation products present in used mineral oil contribute to acidity and these products vary widely in their corrosion properties, the test cannot be used to predict corrosiveness of a mineral oil under service conditions.
