ASTM D2896-06 Standard Test Method for Base Number of Petroleum Products by Potentiometric Perchloric Acid Titration - This test procedure deals with the determination of basic specimens in products by titration with perchloric acid in glacial acetic acid. Test procedures A and B use different titration solvent volumes and sample weights. Additionally, this test method allows for the use of an alternative solvent structure, which eliminates the use of chlorobenzene. The constituents considered to have basic characteristics include amino compounds, organic and inorganic bases, basic salts of polyacidic bases, salts of weak acids (such as soaps), and salts of heavy metals.

ASTM F1277-02 Standard Test Method for Determination of Leachable Chloride in Materials by Ion-Selective Electrode Technique - This test procedure allows for the measurement of chloride ion leached from plastics and composites. Samples containing 7 to 6700 g Cl-/g sample can be analyzed using this method. The upper concentration threshold is extendable by the dilution of the test solution.

ASTM D1125-95 Standard Test Methods for Electrical Conductivity and Resistivity of Water - The following test procedures deal with the determination of the electrical conductivity and resistivity of water. The test methods are as follows – Test Method A - Field and Routine Laboratory Measurement of Non-Flowing (Static) Specimens (Range from 10 to 200,000 S/cm, Sections 12 to 18); Test Method B – Continuous In-Line Measurement (Range from 5 to 200,000 S/cm, Sections 19 to 23). The test procedures have been tested in reagent water.
