Specifies a method for a visual comparison of the tubitity obtained by adding a silver nitrate solution to a solution of a test portion acidified with nitric acid, with that similary obtained from a chloride solution of known concentration. Using a test portion of 50 g, the method is applicable directly to products having inorganic chloride contents in the range 0,0005 % (m/m) to 0,05 % (m/m). This range can be extended by adjusting the mass of the test portion. It has also been approved by the International Union of Pure and Applied Chemistry (IUPAC). ISO 753/1 to ISO 753/11 cancel and replace ISO Recommendation R 753-1968.
