Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of hydrolysable chlorine

ISO 15028:2004 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.
