New and used insulating materials can contain basic constituents which are present as additives. The relative
content of these materials can be determined by titration with acids. The bas number is the measure of the amount of basic substances in the oil always under the conditions of the test.
Acid number is expressed by potassium hydroxide in mg required to neutralize free fatty acid in 1gm of oil.
