DIN EN ISO 25140:2010-12 EN ISO 25140:2010 (E) 3 Introduction Methane (CH4) is a gas of relevance to the climate (greenhouse gas) and contributes directly to the atmospheric gr
24、eenhouse effect. The emissions of methane originate from natural and anthropogenic sources. Significant sources are, for example, cattle breeding, cultivation of rice, extraction and transport of natural gas, and landfills. Other important sources contributing to emissions of methane are, for exampl
25、e, composting plants, the use of biogas and natural gas, and biomass firings. This International Standard specifies a method of measurement for the determination of methane emissions from stationary sources. DIN EN ISO 25140:2010-12 EN ISO 25140:2010 (E) 4 1 Scope This International Standard specifi
26、es the principle, the essential performance criteria, and quality assurance and quality control procedures for an automatic method for measuring methane in the waste gas of stationary sources using flame ionisation detection. It is applicable to measurements of methane in dry or wet waste gases. The
27、 method allows continuous monitoring with permanently installed measuring systems as well as intermittent measurements of methane emissions. NOTE 1 This International Standard is specific to automatic methods for measuring methane in the waste gas of stationary sources using flame ionisation detecti
28、on. It supplements the general requirements of other international or national standards on performance testing, QA/QC procedures, and the test report as specified, for example, in EN 15267-37, EN 141815, and EN 152596. This International Standard does not specify an independent method of measuremen
29、t. NOTE 2 An independent method of measurement, e.g. to calibrate or validate permanently installed measuring systems, is specified in ISO 251393. NOTE 3 In EN 141815, “independent method of measurement” is called “standard reference method (SRM)”. 2 Normative references The following referenced doc
