DUS 2694:2024, Standard Test Method for Base Number of Petroleum Products by Potentiometric Perchloric Acid Titration, First Edition; (20 page(s), in English)

This Draft Uganda Standard covers the determination of basic constituents in petroleum products by titration with perchloric acid in glacial acetic acid. Procedures A and B use different titration solvent volumes and sample weights. The constituents that may be considered to have basic characteristics include organic and inorganic bases, amino compounds, salts of weak acids (soaps), basic salts of polyacidic bases, and salts of heavy metals. This test method can be used to determine base number >300 mg KOH/g.
