ASTM D2074 is the standard test method used to determine the total, primary, secondary, and tertiary amine values of fatty amines through an alternative indicator method. Understanding this standard is essential for industries dealing with lubricants, drilling fluids, engine oils, and other industrial fluids where amines act as critical corrosion inhibitors and acid neutralizers. Overview of ASTM D2074

The standard uses a titration method with perchloric acid in glacial acetic acid, using specific indicators to differentiate between amine classes. This is known as the alternative indicator method , distinguishing it from other ASTM methods like D2073 (potentiometric method).
