The standard was jointly developed by ASTM International's Committee D01 on Paint and Related Coatings, Materials, and Applications, and the American Oil Chemists’ Society. It was a concise 3‑page document containing the entire test procedure, from apparatus and reagent preparation to calculation formulas .
Apply the standard formulas provided in the document to convert the titration volumes (mL) into milligrams of KOHcap K cap O cap H per gram of sample ( ASTM D2073 vs. ASTM D2074: What is the Difference?

(common in universities or large corporate R&D centers). Utilize standards aggregators like IHS Markit or ANSI. astm d2074 pdf
Isopropyl alcohol, chloroform, or toluene mixtures. Indicators: Bromphenol blue or phenolphthalein. Blocking Agents: Salicylaldehyde or acetic anhydride. The Testing Workflow
: The total amine value is typically calculated using the volume and normality of the HClcap H cap C l used in titration relative to the specimen weight.
When evaluating the ASTM D2074 protocol, laboratory personnel focus on several critical parameters: Specification / Requirement Fatty amines, fatty diamines Primary Reagents The standard was jointly developed by ASTM International's
: These tests are vital for quality control in the production of polymers, resins, and paints, as amine values influence the reactivity and curing of these materials. Testing Methodology

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 serve as the foundational backbone for many cationic and amphoteric surfactants. Manufacturers must know the exact amine values to calculate precise stoichiometric ratios during chemical reactions, preventing unreacted materials from contaminating the final product. 2.
