Stationary source emissions - Determination of the mass concentration of sulphur dioxide by instrumental techniques; German version CEN/TS 17021:2017

Overview
This Technical Specification describes a general procedure for sampling and determining the concentration of gaseous sulphur dioxide (SO<(Index)2) in emissions from ducts. This procedure underlies instrumental analysis techniques, but no specific technical procedure is defined. Instead, the minimum requirements for the analyser and the associated sampling equipment, namely for the entire portable automatic measuring system (P-AMS), are described. The process parameters shall meet these minimum requirements. In addition, requirements and recommendations for continuous quality assurance and quality control are specified and described. When using the measurement method described in this Technical Specification as an alternative method (AM) to the standard reference method (SRM), the process parameters shall be determined by an independent test laboratory in a general suitability test according to the test procedures described in EN 15267-4. This also includes the proof of equivalence to the SRM according to DIN EN 14793. This should be taken into account if the measurement method is to be used as part of recurring emission measurements or calibrations of automatic measuring systems (AMS) that are installed stationary on an exhaust gas duct for regulatory or other reasons. This Technical Specification is addressed in particular to manufacturers of portable automatic measuring equipment (P-AMS) for periodic measurements of emissions from stationary sources, to test institutes that carry out performance tests of such measuring equipment, to authorised bodies for the determination of emissions and to authorities responsible for emission monitoring. This Technical Specification deals in particular with aspects of environmental protection and quality control in emission monitoring. Committee NA 134-04-03-10 UA "Emissionsüberwachung mit automatischen Einrichtungen" ("Emission monitoring of automatic systems") at DIN is responsible for this Technical Specification.
