Organization: ASTM
Publication Date: 1 September 2006
Status: inactive
Page Count: 6
ICS Code (Auxiliary materials and additives for plastics): 83.040.30
scope:

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.

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

Test Method B-Applicable to TDI samples containing 0 to 5 % 2,6-isomer (95 to 100 % 2,4-isomer).

NOTE 1-These test methods are equivalent to ISO 15064.

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.
