Workplace atmospheres. Determination of toluene diisocyanate vapours using 1-(2-pyridyl) piperazine-coated glass fibre filters and analysis by high performance liquid chromatography with ultraviolet and fluorescence detectors Ingestion-build-48068 Who is BS EN 43541 Scope This International Standard gives general guidance for the sampling and analysis of airborne toluene diisocyanate (TDI) in workplace atmospheres. The procedure specified in this International Standard is especially suitable for short (15 min) and long term (4 h) sampling and analysis of 2,4 and 2,6 TDI vapours. The upper limit for this method is approximately 85 g of TDI per sample. This is a conservative upper limit based on the requirement
