Determination of Particulate Matter Emissions from Stationary Sources – USEPA Method 5

USEPA Method 5 is used to establish particulate matter (PM) emissions from stationary sources. 
 
Particulate matter is withdrawn isokinetically from the source and collected on a glass fiber filter maintained at a temperature of 120 ± 14°C (248 ± 25°F) or such other temperature as specified by an applicable subpart of the standards or approved by the Administrator for a particular application.  The PM mass, which includes any material that condenses at or above the filtration temperature, is determined gravimetrically after the removal of uncombined water.
