Scope

1.1 These test methods measure the amount of toluene-2,6-diisocyanate (TDI) 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 A -Applicable to TDI samples containing 5 to 95% 2,6-isomer.

1.1.2 Test Method B -Applicable to TDI samples containing 0 to 5% 2,6-isomer.
