When searching for an "astm d2074 pdf," you might also encounter related standards. Here is how they differ:

| Standard | Scope | Key Difference | | :--- | :--- | :--- | | ASTM D2074 | Fatty amines & diamines | Determines total, primary, secondary, tertiary values specifically for long-chain aliphatic amines. | | ASTM D2073 | Fatty amidoamines | Focuses on amidoamines, not free amines. | | ASTM D2579 | Water in amines | Measures moisture content, not amine value. | | ASTM D2074 only covers the titration chemistry specific to fatty amines. | ASTM D2074 vs. Generic Total Base Number (TBN) | ASTM D2896 (TBN) uses perchloric acid in glacial acetic acid, which is stronger and can yield different results for fatty amines. | astm d2074 pdf

The endpoint of the titration is determined by the inflection point on a voltage vs. volume graph. This occurs when the oil’s basic components are fully neutralized. When searching for an "astm d2074 pdf," you
