ASTM D2074

is a standard test method specifically designed to determine the amine values of fatty amines. It provides a chemical analysis procedure to quantify the total, primary, secondary, and tertiary amine content using an alternative indicator method . Scope and Application

: Many university libraries and corporate engineering departments provide access through services like IHS Markit or ASTM Compass. ASTM Standards Volume : This specific standard is found in Volume 06.03 (Paints, Related Coatings, and Aromatics). astm d2074 pdf

• Equipment: An automatic or manual titrator equipped with a glass indicator electrode and a calomel reference electrode.
• Titrant: Hydrochloric acid (HCl) in isopropyl alcohol.
• Process: The HCl is added incrementally. As the acid neutralizes the alkaline components in the oil, the electrical potential between the electrodes changes sharply.

• Accuracy: The standard is generally considered highly accurate when performed by trained technicians. However, the results can be matrix-dependent. Peat is an organic material that can vary widely in composition, so the standard emphasizes the importance of representative sampling.
• Precision: ASTM standards typically provide interlaboratory precision data (repeatability and reproducibility). Users generally find that Method B (Instrumental) offers excellent precision, often better than Method A, provided the instrument is properly calibrated with suitable reference materials.
