Plastics. Aromatic isocyanates for use in the production of polyurethanes. Determination of the isomer ratio in toluenediisocyanate (TDI)1 Scope This document specifies methods for the measurement of toluene 2,6 diisocyanate in mixtures of the 2,4 and 2,6 isomers. Two methods based on infrared spectroscopy are used to give accurate results over a broad range of isomer concentrations. Method A is applicable to toluenediisocyanate (TDI) samples containing between 5 % and 95 % of the 2,6 isomer. Method B is applicable to TDI samples containing 0 % to 5 % of the 2,6 isomer. Both methods
