The method is applicable to products of which the acidity is in the range 2 to 200 µmol of univalent acid per kilogram. Two procedures are given; one applicable to products that are liquid at ordinary temperatures (R 11, R 113, etc.), and the other to products that are gaseous at ordinary temperatures (R 12, R 22, R 114 etc.).
