- Scope
- This standard applies to the determination of phosgene for organized and unorganized emissions from stationary pollution sources. In the analysis of fugitive emission samples, when the sampling volume is 60L, the detection limit of phosgene is 0.02mg/m3, and the concentration range of quantitative determination is 0.06~1. Omg/m3. In the analysis of organized emission samples, when the sampling volume is 15L, the detection limit of phosgene is 0.4mg/m3, and the concentration range of quantitative determination is 1.2~20mg/m3. Under the conditions specified in this standard, when the chlorine concentration is greater than 1600 mg/m3, it will interfere with the determination of phosgene.
