ISO 10283:2007 specifies a gas-chromatographic method for determining monomeric diisocyanates such as toluene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, diphenylmethane diisocyanate and other diisocyanates in isocyanate resins and in solutions prepared from such resins, insofar as these are used in the formulation of paints and similar coating materials.
