Methane Gas Standards

This SAE Recommended Practice describes instrumentation for determining the amount of methane in air and exhaust gas.

This SAE Recommended Practice describes instrumentation for determining the amount of methane in air and exhaust gas.

This Technical Report describes methods for the calculation of the methane number (MN) of dry natural gas when the composition of the gas by mole fraction is known. If the difference of MN between two calculation methods is more than 6, it is recommended to use a test method to...

Optimizing the combustion performance and reducing emissions of methane gas by varying excess air has been and continues to be an area of interest for researchers, manufacturers, and operators of equipment such as gas-fired boilers, with the aim of developing more...

ISO 25139:2011 specifies a manual method for the determination of the concentration of methane emissions from stationary sources. ISO 25139:2011 specifies an independent method of measurement, which is validated for mass concentrations up to 1 500 mg/m3.

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...

5.1 This test method covers the determination of the dissolved gases methane, ethane, ethylene, and propane in drinking, waste, and ground waters, including domestic wells; whether naturally occurring or resulting from commercial activities, dissolved gases can be hazardous...

This test method covers the determination of the dissolved gases methane, ethane, ethylene, and propane in drinking, waste, and ground waters, including domestic wells whether naturally occurring or resulting from commercial activities, or both. This test method has an analytical...

This International standard provides methodology for measuring coalbed methane content of coal core samples obtained by coring or sidewall coring during well drilling. This standard has to be also applied to drill cuttings samples, if the equipment for the determination of the coalbed...

This European Standard specifies the principle, the essential performance criteria and QA/QC procedures of an automatic method for measuring methane (CH4) using the flame ionisation detection (FID) in the waste gas of stationary sources. It is applicable to measurements of...

INTRODUCTION The analysis and interpretation of recent atmospheric, oceanographic, and earth sciences data suggests that significant changes in current global climate patterns may occur as a result of the accumulation of methane (CH4) and other greenhouse gases in the Earth's...
