1 Scope
This Standard specifies a gas-chromatographic method for determining monomeric diisocyanates. This Standard is applicable to monomeric diisocyanates such as toluene diisocyanate 1), hexamethylene diisocyanate, isophorone diisocyanate 2), diphenylmethane diisocyanate 3) and other diisocyanates in isocyanate resins as defined in Chapter 3 and in solutions prepared from such resins, insofar as these are used in the formulation of paints and similar coating materials.
