Extent: E+W+S+N.I.

The iodine value is given by the expression
12,69 c V 1 − V 2 m
where:
c is the numerical value of the exact concentration, in moles per litre, of the standard volumetric sodium thiosulfate solution (4.4) used;
V1 is the numerical value of the volume, in millilitres, of the standard volumetric sodium thiosulfate solution (4.4) used for the blank test;
V2 is the numerical value of the volume, in millilitres, of the standard volumetric sodium thiosulfate solution (4.4) used for the determination;
m is the numerical value of the mass, in grams, of the test portion (7.1).
Take as the result the arithmetic mean of the two determinations, provided that the requirement for repeatability (9.2) is satisfied.
