Insulating liquids. Determination of acidity - Test methods for non mineral insulating oils PAS 15 Note 4: ISO 11138-7 doesWhat 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
