Test methods for stationary sources:
Method 2G: Determination of stack gas velocity and volumetric flow rate with two-dimensional probes.
Method 2H: Determination of stack gas velocity taking into account velocity decay near the stack wall.
Method 3: Gas analysis for the determination of dry molecular weight.
Method 3A: Determination of oxygen and carbon dioxide concentrations in emissions (instrumental analyzer procedure).
Method 3B: Gas analysis for the determination of emission rate correction factor or excess air.
Method 3C: Determination of carbon dioxide, methane, nitrogen, and oxygen.
