Plastics. Polyurethane raw materials. Determination of isocyanate content Ingestion-build-190310 generators and motors1 Scope 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, methylene bis (4 phenylisocyanate) and polymethylene
