1.1 This specification covers toluene diisocyanate used as an ingredient in the production of polyurethane cellular materials. The properties included in this specification are those required to characterize toluene diisocyanate. Other requirements may become necessary and will be added as the necessary test methods become available.
There is no equivalent ISO standard.
This specification covers toluene diisocyanate used as an ingredient in the production of polyurethane cellular materials. The three classes of toluene diisocyanate covered in this specification are based on isomer ratio, and the three types are based on acidity and hydrolyzable chloride. Materials shall be tested and the individual grades shall conform to specified values of isomer ratio, purity, APHA color, and total chlorine.
