This lnternational Standard specifies two methods for the measurement of the isocyanate content of aromatic
isocyanates used as polyurethane raw materials. Method A is primarily applicable to refined toluene
diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B is applicable
to refined, crude or modified isocyanates derived from toluene diisocyanate, methylenebis-(
4-phenylisocyanate) and polymethylene polyphenylisocyanate. It can also be used for isomer mixtures of
toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. Other
aromatic isocyanates may be analysed by this method if precautions are taken to verify suitability. It is not
applicable to blocked isocyanates.
