6、2-00-02 AA Lackrohstoffe. Determination of iodine value: The Committee did not agree to include the iodine value according to the Wijs method (see DIN 53241-1, Determination of iodine value Part 1: Methods using Wijs solution), since the use of 155 mg iodine/g to 175 mg iodine/g is no measure of the
7、 degree of unsaturation of the tung oil, whereas the determination of the iodine value according to the Woburn method (as specified in DIN 55936) comes very close to the real value. Even more suitable is the determination of the hydrogenated iodine value (as specified in DIN 53241-2, Iodine number D
8、etermined by hydrogenation, withdrawn 1991-04). The real value is most likely to be determined by the gas-chromatographic analysis of the fatty acids. This method as described in ISO 277:2002 is therefore recommended for the determination of the iodine value. The DIN Standards corresponding to the I
