This document specifies a method for the sampling and analysis of airborne organic isocyanates in workplace air.
This document is applicable to a wide range of organic compounds containing isocyanate groups,including monofunctional isocyanates (e.g. phenyl isocyanate), diisocyanate monomers [e.g.1,6-hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI), 4,4′-diphenylmethane diisocyanate (MDI), and isophorone diisocyanate (IPDI)], prepolymers (e.g. the biuret and isocyanurate of HDI), as well as chromatographable intermediate products formed during production or thermal breakdown of polyurethane.
