Determination of Particulate Matter Emissions from the Wool Fiberglass Insulation Manufacturing Industry – USEPA Method 5E

USEPA Method 5E applies to the determination of Particulate Matter (PM) emissions from wool fiberglass insulation manufacturing sources.
 
Particulate matter is withdrawn isokinetically from the source and is collected on a glass fiber filter maintained at a temperature in the range of 120 ± 14 °C (248 ± 25 °F) and in impingers containing solutions of 0.1 N sodium hydroxide (NaOH).  The filtered particulate mass, which includes any material that condenses at or above the filtration temperature, is determined gravimetrically after the removal of uncombined water.  The condensed PM collected in the impinger solutions is determined as total organic carbon (TOC) using a nondispersive infrared hydrocarbon analyzer.  The sum of the filtered PM mass and the condensed PM is reported as the total PM mass.
