Standard Test Method for Polyurethane Raw Materials: Determination of Acidity as Acid Number for Polyether Polyols
Importancia y uso:
5.1 This test method is suitable for quality control, as a specification test, and for research. Acid numbers indicate the extent of any neutralization reaction of the polyol with acids. The results of this method measure batch-to-batch uniformity and are used as correction factors in calculating true hydroxyl numbers.
