Adhesives - Determination of acid value
This standard specifies a method for determination of the acid
value of adhesives, adhesive components, their basic constituents, and related products. In some cases, notably when unsaturated polyesters with free anhydrides are present, somewhat lower than theoretical acid values are found, due to the formation of acid esters which precipitate and, are therefore, not determined.
Diese ÖNORM beschreibt ein Verfahren zur Bestimmung der Säurezahl von Klebstoffen, deren Grundstoffen und verwandten Produkten.
