ASTM D664 Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D664 testing. This test method covers procedures for the determination of acidic components in petroleum products, lubricants, biodiesel and biodiesel blends.

ASTM D664 Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration

Test Method A, Soluble or nearly soluble in mixtures of toluene and propan-2-ol for petroleum products and lubricants. The range of acid numbers included in the precision expression is 0,1 mg ⁄g KOH to 150 mg ⁄g KOH.

Test Method B was developed specifically for Biodiesel and tests blends of biodiesel with low acidity and slightly different solubility. This test method requires the use of an automatic titrator with automatic endpoint search.

The test method can be used to specify relative. Changes that occur in the oil during use under oxidizing conditions, regardless of the color or other properties of the oil formed. Although the titration is done under certain equilibrium conditions, the test method is not intended to measure an absolute acidic property that can be used to predict the oil's performance under service conditions.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
