Official basis (Research): ASTM D4607 is an iodine-number method and does not validate either dye assay. Retain dye uptake only as a separately validated research test.
Procurement note: Research adsorption test. Record dye grade and hydration state; solvent, pH, matrix and optical interference determine consumables and interpretation.
