Stationary source emissions. Determination of the water vapour in ducts. Standard reference method1 Scope This European Standard specifies the standard reference method (SRM) based on a sampling system with a condensation adsorption technique to determine the water vapour concentration in the flue gases emitted to atmosphere from ducts and stacks. This European Standard specifies the performance characteristics to be determined and performance criteria to be fulfilled by measuring systems based on the measurement method. It applies to periodic
