Gives two methods for measuring the isocyanate content of aromatic isocyanates used as polyurethane raw materials. Method A applies to refined toluene diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B applies to refined, crude or modified isocyanates derived from toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate.
