Adopts ANSI standard X3.53-1976 and French standard NF Z 65-500 as PL/1 programming language standard for the English and French versions, respectively.
Specifies an acid washing test. Gives some indication of the degree of refining but does not give a precise measure of the amount of unsaturated compounds present as different unsaturated compounds produce different colourations with sulphuric acid. Shaking together of equal volumes of the sample and 95 % (m/m) sulphuric acid. Comparison of the colour of the acid layer with that of standard…

Inorganic chemical products for industrial use — General method for determination of chloride conten...
Covers a method enabling quantities of chloride eceeding 1 mg in the test portion to be determined with an absolute error of 0,2 to 0,5 mg, according to the concentration of the standard volumetric solution used. The principle of determination is based on the conversion of chloride ions into weakly ionized mercury(II) chloride, using highly ionized standard volumetric mercury(II) nitrate solution…
Vegetable products — Determination of chloride content
The method consists in precipitating chloride by addition of an excess of a standard volumetric silver nitrate solution and titrating this excess with a standard volumetric potassium thiocyanate solution. If the product contains natural anthocyanin pigments, the method is applicable with specified modifications.
Cryolite, natural and artificial, and aluminium fluoride for industrial use — Determination of sulph...
Covers a method, the orinciple of which consists in preparing tablets from a mixture of the test portion and a binder and measuring the intensity of the K line emitted by the sulphur. The measured intensity is then compared with the intensity of emission of standard tablets of known sulphur content. The method is applicable to products having sulphur contents between 0,01 and 2 % (m/m).
