BS EN 14793 specifies the standard reference method (SRM) based on the infrared (IR) absorption principle. It includes the sampling and the gas conditioning system and allows the determination of the carbon monoxide (CO) in flue gases emitted to the atmosphere from ducts and stacks.
BS EN 14793 specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems (P-AMS) using the IR measurement method. It applies for periodic monitoring and for the calibration or control of automated measuring systems AMS) permanently installed on a stack, for regulatory or other purposes.
BS EN 14793 specifies criteria for demonstration of equivalence of an alternative method AM) to the SRM by application of EN 14793:2017.
Note: The characteristics of installations, the conditions during field tests and the values of repeatability and reproducibility in the field are given in Annex A.
BS EN 15058 on stationary waste emissions is relevant to:
Non-dispersive infrared spectroscopy (ND-IR) has often been used to detect and measure the concentration of carbon oxides (e.g., carbon monoxide, carbon dioxide).
BS EN 15058 specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems (P-AMS) based on this measurement method.
Overall, BS EN 14791 benefits you as a buyer as it specifies a standard reference method (SRM) that is based on a sampling system for sampling carbon monoxide in flue gases emitted to the atmosphere from ducts and stacks that reduce pollution caused by harmful gases.
