Total Base Number Standards

Total Base Number Standards

 The test method for determining Total Base Number (TBN) is used to determine basic constituents in oils and lubricants such as organic bases, inorganic bases, amino compounds, salts of weak acids (soaps), basic salts of polyacidic bases and salts of heavy metals. The methodology of performing the test involves dissolving the sample in an anhydrous mixture of chlorobenzene/glacial acetic acid and titrating potentiometrically with a solution of perchloric acid in glacial acetic acid. TBN Standards come in a 50g package prepared in a synthetic base oil matrix and are available in the following concentrations: 1.0, 3.0, 6.0, 10, 15, 30, 40 and 50 mg/g KOH.
