This International Standard gives general guidance for the sampling and analysis of airborne toluene diisocyanate (TDI) in workplace air. This standard procedure is specifically recommended for short (15-min) and long-term (4-hours) sampling and analysis of 2,4- and 2,6-TDI vapors. The quantitation limits for this method are 0.039 μg for 2,4-TDI and 0.034 μg for 2,6-TDI using a fluorescence detector. These limits for a 15-min sample collected at 1 l/min are equivalent to 0.36 parts per billion (ppb) for 2,4-TDI, and 0.32 ppb for 2,6-TDI. For a 4-hour sample collected at 1 l/min, the limits are equivalent to 0.022 ppb for 2,4-TDI and 0.020 ppb for 2,6-TDI. The commercial availability of the specified reagents, the use of common analytical instrumentation, and the current widespread use of the method make this standard method ideally suited for the determination of TDI in workplace environments.
