ISO 17734-1:2006给出了工作场所空气中气载异氰酸酯取样和分析的一般指南。该方法适用于气相和颗粒相中多种异氰酸酯的测定。可测定的典型单官能团异氰酸酯为异氰酸酯(ICA)、甲基异氰酸酯(MIC)、乙基异氰酸酯(EIC)、丙基异氰酸酯(PIC)、丁基异氰酸酯(BIC)和苯基异氰酸酯(PhI)。典型的单体二异氰酸酯包括1,6-六亚甲基-(HDI)、2,4-和2,6-甲苯-(TDI)、4,4'-二苯基甲烷-(MDI)、1,5-萘-(NDI)、异佛尔酮-(IPDI)和4,4'-二环己基甲烷二异氰酸酯(HMDI)。可测定的多功能异氰酸酯通常是聚合物MDI、缩二脲中的低聚物-异氰脲酸盐和异氰脲酸盐加合物以及异氰酸酯的预聚物形式。

ISO 17734-1:2006 gives general guidance for the sampling and analysis of airborne isocyanates in workplace air. The method is suitable for the determination of a wide range of different isocyanates in both the gas and particle phases. Typical monofunctional isocyanates that can be determined are isocyanic acid (ICA), methyl isocyanate (MIC), ethyl isocyanate (EIC), propyl isocyanate (PIC), butyl isocyanate (BIC), and phenyl isocyanate (PhI). Typical monomeric diisocyanates include 1,6-hexamethylene- (HDI), 2,4- and 2,6-toluene- (TDI), 4,4'-diphenylmethane- (MDI), 1,5-naphthyl- (NDI), isophorone- (IPDI), and 4,4'-dicyclohexylmethane diisocyanate (HMDI). Multifunctional isocyanates that can be determined are typically oligomers in polymeric MDI, biuret-, isocyanurate-, and allophanate-adducts and prepolymeric forms of isocyanates.
