If your laboratory needs to perform this test, you must adhere strictly to the written standard to ensure compliance and traceability. You cannot typically source valid, legally compliant, or up-to-date versions of technical standards from unverified document-sharing sites.
Fatty amines are excellent asphalt emulsifiers and corrosion inhibitors . The amine value dictates how effectively an amine will act as a curing agent in epoxy resins or as an anti-stripping agent in asphalt, making ASTM D2074 essential for construction material quality assurance.
This article provides a comprehensive overview of ASTM D2074, its significance, the test methods it covers, how to obtain the official PDF, and best practices for compliance.
Because of these wide‑ranging uses, even a withdrawn standard can remain important for quality control in older facilities or when comparing historical data. astm d2074 pdf

Isopropyl alcohol, chloroform, or toluene mixtures. Indicators: Bromphenol blue or phenolphthalein. Blocking Agents: Salicylaldehyde or acetic anhydride. The Testing Workflow
[ Sample Preparation ] │ ├──> Titration 1: Total Amine Value (Direct titration with Acid) │ ├──> Titration 2: Secondary + Tertiary Amine Value (Salicylaldehyde blocks Primary Amines) │ └──> Titration 3: Tertiary Amine Value Only (Acetic Anhydride blocks Primary & Secondary Amines) If your laboratory needs to perform this test,
ASTM D2074 is a standard test method developed by ASTM International (Committee D01 on Paint and Related Coatings, Materials, and Applications). It outlines alternative procedures for determining the total, primary, secondary, and tertiary amine values of fatty amines. What is an "Amine Value"?
When researching fatty amine analysis, researchers frequently encounter both ASTM D2073 and ASTM D2074. ASTM D2073 ASTM D2074 Potentiometric Titration (pH electrode) Visual Indicator Titration (Color change) Equipment Cost Higher (Requires a digital titrator/pH meter) Lower (Requires basic glass burettes) Sample Suitability Excellent for dark, highly coloured samples
: A separate sample is treated with salicylaldehyde or PITC, which reacts specifically with primary amines to form a derivative that is no longer titratable. The remaining basic species (secondary and tertiary amines) are then titrated with HCl. The difference between the total amine value and this value gives the primary amine content. The amine value dictates how effectively an amine
