Workplace air quality. Determination of total organic isocyanate groups in air using 1-(2-methoxyphenyl) piperazine and liquid chromatography1 Scope This International Standard gives general guidance for the sampling and analysis of airborne organic isocyanate (NCO) compounds in workplace air. This International Standard is appropriate for a wide range of organic compounds containing isocyanate functional groups, including isocyanatemonomers and prepolymers. Examples of aromatic monomers include toluene diisocyanate (TDI) (both 2,4 and 2,6 diisocyanatotoluene), naphthyl diisocyanate (NDI)

This European Standard specifies a method of assessing the behaviour of protection sleeves or conduits subject to an external electric arc
