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/m.
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 method of measurement” is termed “standard reference method (SRM)” in EN 14181.
