ISO 16702:2007为工作场所空气中空气中有机异氰酸酯(NCO)化合物的采样和分析提供了一般指南。 ISO 16702:2007适用于多种含有异氰酸酯官能团的有机化合物，包括异氰酸酯单体和预聚物。含有单个异氰酸酯部分的单体(例如异氰酸甲酯、异氰酸乙酯、异氰酸苯酯、异氰酸己酯)在聚氨酯的热降解过程中产生，即火焰粘合和激光切割。异氰酸酯聚合物，也称为多异氰酸酯、均聚物、低聚物或预聚物，通过自缩合或与多元醇反应由二异氰酸酯单体衍生。聚合二异氰酸酯广泛用于聚氨酯、油漆和涂料以及粘合剂工业。 ISO 16702:2007适用于测量任何含有游离异氰酸酯基团的产品。它主要针对常用的亚甲基双（苯基异氰酸酯）（MDI）、1,6-（二异氰酸酯）己烷（HDI）和甲苯二异氰酸酯（TDI）及其低聚物和聚合物开发。它还用于异佛尔酮二异氰酸酯（IPDI）、氢化亚甲基双（苯基异氰酸酯）（HMDI）和萘基二异氰酸酯（NDI）及其低聚物和聚合物。 该方法用于测定工作场所大气中有机异氰酸酯的时间加权平均浓度，适用于0.5分钟至8小时范围内的采样。该方法设计用于个人监测，但也可以通过适当的修改用于固定位置监测。 该方法适用于测量空气中浓度范围为约0.1 μ g/m3至140 μ g/m3的有机异氰酸酯，样品体积为15 l。

ISO 16702:2007 gives general guidance for the sampling and analysis of airborne organic isocyanate (NCO) compounds in workplace air. ISO 16702:2007 is appropriate for a wide range of organic compounds containing isocyanate functional groups, including isocyanate monomers and prepolymers. Monomers containing a single isocyanate moiety (e.g. methyl isocyanate, ethyl isocyanate, phenyl isocyanate, hexyl isocyanate) are produced during thermal degradation of polyurethanes, i.e. flame bonding and laser cutting. Isocyanate polymers, also called polyisocyanates, homopolymers, oligomers or prepolymers, are derived from the diisocyanate monomers by self-condensation or reaction with polyols. Polymeric diisocyanates are widely used in the polyurethanes, paints and coatings, and adhesives industries. ISO 16702:2007 is appropriate for measuring any product containing free isocyanate groups. It was developed primarily for the commonly used methylenebis(phenylisocyanate) (MDI), 1,6-(diisocyanato)hexane (HDI), and toluene diisocyanate (TDI) and their oligomers and polymers. It has also been used for isophorone diisocyanate (IPDI), hydrogenated methylenebis(phenylisocyanate) (HMDI), and naphthyldiisocyanate (NDI), and their oligomers and polymers. The method is used to determine time-weighted average concentrations of organic isocyanates in workplace atmospheres, and is suitable for sampling over periods in the range 0,5 min to 8 h. The method is designed for personal monitoring, but can also be used for fixed location monitoring by suitable modification. The method is suitable for the measurement of airborne organic isocyanates in the concentration range from approximately 0,1 μg/m³ to 140 μg/m³ for a 15 l sample volume.
