1.1 These test methods measure the amount of toluene-2,6-diisocyanate (TDI) or toluene-2,4-diisocyanate in mixtures of the 2,4- and 2,6-isomers. Two test methods are required to give accurate results over a broad range of isomer concentrations.

1.1.1 Test Method AApplicable to TDI samples containing 5 to 95 % 2,6-isomer (95 to 5 % 2,4-isomer).

1.1.2 Test Method BApplicable to TDI samples containing 0 to 5 % 2,6-isomer (95 to 100 % 2,4-isomer). These test methods are equivalent to ISO 15064.
