ISO 17734-2:2006给出了工作场所空气中空气中胺和氨基异氰酸酯采样和分析的一般指南。该方法可用于同时测定胺、4,4'-亚甲基二苯二胺(4,4'-MDA)、2,4-和2,6-甲苯二胺(2,4-、2,6-TDA)和1,6-己二胺(1,6-HDA),以及同时含有异氰酸酯和胺基的化合物、4,4'-亚甲基二苯氨基异氰酸酯(4,4'-MAI)、2,4-、4,2-和2,6-甲苯氨基异氰酸酯(2,4,4,4,2-TAI),1,6-六亚甲基氨基异氰酸酯(1,6-HAI)。该方法适用于收集气相和颗粒相中的胺和氨基异氰酸酯。
ISO 17734-2:2006 gives general guidance for the sampling and analysis of airborne amines and aminoisocyanates in workplace air. The method can be used for simultaneous determinations of amines, 4,4'-methylenediphenyldiamine (4,4'-MDA), 2,4- and 2,6-toluenediamine (2,4-, 2,6-TDA) and 1,6-hexamethylenediamine (1,6-HDA), and compounds containing both isocyanate and amine groups, 4,4'-methylenediphenyl aminoisocyanate (4,4'-MAI), 2,4-, 4,2- and 2,6-toluene aminoisocyanate (2,4, 4,2, 2,6-TAI), 1,6-hexamethylene aminoisocyanate (1,6-HAI). The method is suitable for collecting amines and aminoisocyanates in both the gas and particle phases.
