Online EPA Method 1 Training: Isokinetic Stack Sampling Course

EPA Method 1: Isokinetic Air Emission Testing

Isokinetic air emission sampling has been employed since the 1950’s to measure air pollutants such as particulate matter, aerosols, dusts, mists and smoke in flue gases from stack and ducts. EPA Methods 1-4 provide all the necessary data to perform any of the isokinetic sampling methods published by the Environmental Protection Agency and other isokinetic methods developed by other institutions. Each isokinetic method is specific to the target pollutant with variations to the sampling train to accommodate the target pollutant. The equations, techniques, and skills are universal in the operation of isokinetic sampling. EPA Method 2 is for the determination of the average velocity and volumetric flow rate of a gas stream. This method employs the principals of EPA Method 1 in selecting an appropriate measurement location and determining the minimum number of measurement points to provide reliable velocity and volumetric flow rate determination. Some material of Method 2 is incorporated by reference from other methods. To obtain reliable results, persons using this method should have a thorough knowledge of at least Method 1.
