Astm D2074 Pdf

There is a common industry question: "Do we still need D2074 given the rise of D2896?"

Answer: Yes. While D2896 is more common for new oils, it uses perchloric acid in glacial acetic acid—a hazardous combination. ASTM D2074 uses safer alcoholic HCl. Furthermore, for extremely dark, soot-laden used oils, D2074 often provides more repeatable results due to its specific solvent system and weaker acid strength, which better mimics real-world acid neutralization.

The repeatability (within a single lab) for total amine value is approximately ±1-2% relative standard deviation (RSD). Reproducibility (between labs) is higher, around ±3-5% RSD. astm d2074 pdf

ASTM D2074 outlines two distinct wet-chemistry procedures for quantifying nitrogen:
