1.1 This test method determines the hydrolyzable chlorine content of toluene-2,4-diisocyanate, toluene-2,6-diisocyanate, or mixtures of the two. This test method may also be applied to other isocyanates of suitable solubility. (See Note 0.) The main sources of hydrolyzable chlorine in the isocyanates are carbamoyl chloride and dissolved phosgene. Both of these compounds react with alcohols and water, forming ureas, carbamates, carbon dioxide, and hydrochloric acid. (See Note 2.)<\/p>\n

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.<\/i><\/p>\n

Note 1 <\/p>\n

This test method may be applicable with crude polymeric isocyanates. However, the precision with crude polymeric isocyanates has not been established.<\/p>\n

Note 2 <\/p>\n

There is no equivalent ISO standard.<\/p>\n
