适用范围：This European Standard specifies a procedure for the determination of volatile isocyanates in the exhaust airof an emission test chamber after application of a low-solvent or solvent-free adhesive as defined in EN 923.The method is based on chemosorption of volatile isocyanates with 1-(2-methoxyphenyl) piperazine (in thefollowing: 1-2MP) impregnated filters with subsequent desorption and liquid chromatographic analysis. Themethod permits measurement of a wide range of organic compounds containing isocyanate functional groups(NCO), including isocyanate monomers. For testing of adhesives emissions mainly toluene diisocyanate (TDI)and methylene bis (4-phenyl isocyanate also known as 4,4-diisocyanato-diphenylmethane or MDI), are ofconcern. The method as described in this European Standard can be used for other isocyanates too, such asisophorone diisocyanate (IPDI) and 1,6-hexamethylene diisocyanate (HDI) - see ISO 16702. Isocyanateoligomers or prepolymers are not volatile enough to be detected in emission test chambers at roomtem perature.
