This standard specifies the method to manually sample volatile organic compounds (VOCs) in stationary source emission less than 150℃ with thin film gas bag made of polyvinyl fluoride (PVF) and fluoropolymer.
This standard is applicable to the sampling of non-methane hydrocarbon and some VOCs in stationary source emission; VOCs applicable to this method include compounds which may be preserved stably in the gas bag made of material(s) adopted through experimental verification. See Appendix A for performance indexes of 61 kinds of VOCs preserved in thin film gas bags made of three kinds of fluorine polymers.
