ISO 15028:2014规定了测定甲苯-2,4-二异氰酸酯、甲苯-2,6-二异氰酸酯或二者混合物中可水解氯含量的方法。本试验方法也可适用于具有适当溶解度的其他异氰酸酯，如粗异氰酸酯或精制聚合物异氰酸酯。

ISO 15028:2014 specifies a method for the determination of the hydrolysable-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, such as crude or refined polymeric isocyanates.
