This European Standard shall be given the status of a national standard, either
21、by publication of an identical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association
22、, and supports essential requirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Ger

24、(E) 4 1 Scope This European Standard specifies the Standard Reference Method (SRM) for sampling, and determining car-bon monoxide content in ducts and stacks emitting to atmosphere. It describes the Non Dispersive Infra-Red (NDIR) analytical technique, including the sampling system and sample gas co
25、nditioning system, to determine CO in flue gases. This European Standard is the reference method for periodic monitoring and for calibration or control of Automatic Measuring Systems (AMS) permanently installed on a stack, for regulatory purposes or other purposes. To be used as the SRM, it is neces
26、sary to demonstrate that the performance characteristics of the method are lower than the performance criteria defined in this European standard and that the overall uncertainty of the method is less than 6 % relative at the daily Emission Limit Value (ELV). NOTE When the NDIR method is used as an A
27、MS, refer to EN 14181 and other relevant standards provided by CEN TC 264. It is necessary for anybody who would like to use an Alternative Method instead of this Standard Reference Method to work out the demonstration of the equivalence according to the Technical Specification TS 14793, providing t
28、hat his capability to carry out this demonstration is officially recognised by his national accreditation body or law. This Standard Reference Method has been evaluated during field tests on waste incineration, co-incineration installations and large combustion plants. It has been validated for CO c
29、oncentrations with sampling periods of 30 min in the range of 0 mg/m3to 400 mg/m3for large combustion plants and 0 mg/m3 740 mg/m3for waste and co-incineration. For waste incineration plants, Council Directive 2000/76/EC lays down emission values which are expressed in mg/m3, on dry basis at a speci
30、fied value of O2and at reference conditions of 273 K and 101,3 kPa. 2 Normative references The following referenced documents are indispensable for the application of this document.
