Developed by the United States Environmental Protection Agency (EPA), the EPA 5 method describes a test method for determining particulate matter emissions from stationary sources: Method 5 Particulate matter (PM).

Particulate matter is drawn isokinetically from the source and is collected on a fiberglass filter maintained at 120 degrees (plus minus 14 degrees Celsius) or another temperature specified by an applicable subsection of the standards or approved by the administrator. The mass of particulate matter containing any material condensed at or above the filtration temperature is determined gravimetrically after removal of unconsolidated water.
This method may involve hazardous materials, processes and equipment. This test method may not address all security issues associated with its use. It is the responsibility of the testers to establish appropriate safety and health practices and determine the applicability of regulatory restrictions prior to using this test method.
When determining particulate matter emissions from stationary sources, the EPA 17 method is used for points without high humidity and the EPA 5 method for points with high humidity.
In our organization, testing, analysis, measurement, and evaluation studies comply with national and international standards and current legal regulations, ensuring reliable and impartial results. These studies are based on state-of-the-art technological equipment, a trained and experienced staff, and modern methods. Among the numerous tests conducted within this scope are services for determining dust emission levels in flue gas under nominal reference temperature conditions (EPA 5 method).
