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. Note 1--There are no equivalent ISO standards. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning and precautionary statements see Note 3. |
