DIN EN 13999-4:2007 PDF

Scope: This European standard specifies a procedure for the determination of volatile isocyanates in the exhaust air of 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 the following:1-2MP)impregnated filters with subsequent desorption and liquid chromatographic analysis.The method 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 knownas 4,4-diisocyanato-diphenylmethane or MDI),are of concern. The method as described in this European standard can be used for other isocyanates too,such as isophorone diisocyanate(IPDI)and 1,6-hexamethylene diisocyanate(HDI)-see ISO 16072.Isocyanate oligomers or prepolymers are not volatile enough to be detected in emission test chambers at room temperature.
