What is BS EN 62021-3 -  Non-mineral insulating oils about  ?

BS EN 62021-3 is a European Standard which is the third part of a multi-series that describes two procedures for the determination of the acidity of unused and used electrical non-mineral insulating oils. Method A is potentiometric titration and Method B is colourimetric titration. The method may be used to indicate relative changes that occur in non-mineral insulating oil   during use under oxidizing conditions regardless of the colour or other properties of the   resulting non-mineral oil. The acidity can be used in the quality control of unused non-mineral insulating oil. Note 1: In unused and used non-mineral insulating oils, the constituents that may be considered to have acidic characteristics include organic aci...
