This Recommended Practice incorporates methane analysis instrumentation only.

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

The method presented applies to the analysis of the indicated constituents in diesel engine exhaust, or vehicles using diesel engines, when operating at steady-state conditions. The measurements of carbon monoxide, carbon dioxide, and nitric oxide are based on continuous sampling and analysis by nondispersive infrared (NDIR) methods. Measurement of total oxides of nitrogen by chemiluminescence and NDIR methods is discussed. This SAE Recommended Practice provides for the measurement of carbon dioxide, carbon monoxide, and oxides of nitrogen in diesel exhaust.

This procedure establishes recommendations on the measurement of diesel engine intake air flow under steady-state test conditions. The measurement methods discussed have been limited to metering systems and associated equipment found in common usage in the industry, specifically, nozzles, laminar flow devices, and vortex shedding. The procedure establishes accuracy goals as well as explains proper usage of equipment. The recommendations concerning diesel engine exhaust mass flow measurements are minimal in scope.

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

This SAE Recommended Practice establishes equipment and test procedures for determining the performance of spark arrester exhaust systems of multiposition small engines (<19 kW) used in portable applications, including hand-held, hand-guided, and backpack mounted devices. It is not applicable to spark arresters used in vehicles or stationary equipment.
