Summary: This standard specifies the end -use and used electrical insulating mineral acid value measurement method. Note: the unused and used electrical mineral insulating oil, the acidic ingredients, including organic acids, phenolic compounds, oxidation products, resins, metal salts and organic additives. 1. 2 Wood standard mineral insulating oil can be used to indicate the oxidation conditions of use relative changes that occur regardless of whether the performance of their color or other change. 1. 3 Acid can be used for unused mineral insulating oil quality electrical control. 1. 4 used electrical insulating mineral oil present in a variety of oxidation products will be on acid affected, and these different corrosive oxidation products, the standards can not be used to predict the use of mineral insulating oil for electrical resistance. Note: The acid value of the standard measurement results with GB/T 4945 and GB/T 7304 The results of measurement values ??can be the same or may be different vessels, it is usually the same order of magnitude.
