Insulating liquids. Determination of acidity - Test methods for non mineral insulating oils1 Scope This part of IEC 62021 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. NOTE 1 In unused and used non mineral insulating oils, the constituents that may be considered to have acidic characteristics include organic acids, phenolic compounds, some oxidation products, resins, organometallic salts
