Scope

The principle of the method consists in dilution of a test portion with carbon dioxide-free water, titration of the test solution, if acid, with standard volumetric sodium hydroxide solution, using phenolphthalein as indicator. The method is applicable to products having acidities, expressed as acetic acid, equal to or greater than 0,0006 % (m/m). International Standards ISO 757/1 to ISO 757/5 cancel and replace ISO Recommendation R 757-1968, of which they constitute a technical revision. This document has also been approved by the International Union of Pure and Applied Chemistry (IUPAC).
