27、 BS EN 15058:2017EN 15058:2017 (E) 6 1 Scope This European Standard 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

28、 the atmosphere from ducts and stacks. This European Standard 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 con

29、trol of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes. This European Standard specifies criteria for demonstration of equivalence of an alternative method (AM) to the SRM by application of EN 14793:2017. This European Standard has been validated

30、 during field tests on waste incineration, co-incineration and large combustion plants and on a recognized test bench. It has been validated for CO concentrations with sampling periods of 30 min in the range of 0 mg/m3to 400 mg/m3for large combustion plants and 0 mg/m3to 740 mg/m3for waste and co-in

31、cineration. Directive 2010/75/EU lays down emission values which are expressed in mg/m3, on dry basis at a specified value of oxygen and at standard conditions (273 K and 101,3 kPa). NOTE The characteristics of installations, the conditions during field tests and the values of repeatability and repr

32、oducibility in the field are given in Annex A. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
