Original text. Later amendments are not shown.

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.
