The primary purpose of stack testing is to measure the emission rate of pollutants. This process involves collecting and analyzing samples from the exhaust stack of a facility to determine the quantity of specific pollutants being released into the atmosphere. Measuring these emissions is crucial for ensuring compliance with environmental regulations and standards, as it helps assess the environmental impact of a facility's operations.

In addition to compliance, stack testing provides valuable data that can be used to evaluate the effectiveness of control technologies, monitor changes in emissions over time, and guide improvements in processes to minimize pollution. This is particularly relevant for industries subject to stringent emissions standards, as accurate measurements allow for a clearer understanding of a facility's environmental performance and compliance status.
