Method 201A

Determination of PM10 Emissions (Constant Sampling Rate Procedures)

This method is a procedure for measuring particulate matter emissions equal to or less than an aerodynamic diameter of nominally 10µm (PM10) in stationary source emissions using a constant sampling rate. You must document your adherence to these specific requirements for equipment, supplies, sample collection and analysis, calculations, and data analysis.
