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.
