Some proficiency testing providers include a copy of the standard with their registration fee.
Note on Versions: Always ensure you are downloading the active version. ASTM D2074 was last reapproved in 2019 (D2074-07(2019)). Do not use withdrawn versions like D2074-92.
Without a standardized method like ASTM D2074, different laboratories could produce wildly different results for the same batch of fatty amine. This variability would lead to: astm d2074 pdf
Using the official astm d2074 pdf ensures that your lab follows a globally recognized, repeatable, and accurate procedure, allowing for apples-to-apples comparisons with suppliers and customers worldwide.
ASTM D2074 is a standard test method developed by ASTM International (formerly known as the American Society for Testing and Materials). The full title is: "Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines." Some proficiency testing providers include a copy of
This standard is essential for the analysis of aliphatic amines, diamines, and their derivatives, which are widely used in:
The "amine value" is a measure of the basicity of a sample, expressed as the equivalent number of milligrams of potassium hydroxide (KOH) per gram of sample. ASTM D2074 breaks this down into four distinct categories: Note on Versions: Always ensure you are downloading
Total Base Number measures the alkalinity of an oil. In lubricants (especially engine oils), TBN indicates the ability to neutralize acids formed during combustion. A high TBN means the oil has significant reserve alkalinity to fight corrosion and sludge.
However, standard TBN tests (like color-indicator titration) fail with dark oils because you cannot see the color change of the indicator. This is where ASTM D2074 becomes essential. It uses a potentiometric method (measuring voltage changes) rather than a visual color change, making it immune to the oil's opacity.
