Stationary source emissions. Manual method for the determination of the methane concentration using gas chromatography Ingestion-build-276583 The QOS aspects of these1 Scope This International Standard specifies a manual method for the determination of the concentration of methane emissions from stationary sources. This International Standard specifies an independent method of measurement, which is validated for mass concentrations up to 1 500 mg m3. NOTE 1 An independent method of measurement is used for such purposes as calibration or validation of permanently installed measuring systems. NOTE 2 An independent
