Stack testing companies specialize in air emissions testing for compliance with standards and test methodologies set out by the Environmental Protection Agency (EPA). Manufacturing and processing industries such as Pulp and Paper, Cement, Pharmaceutical, and Petrochemical, use a large variety of air emissions sources — like baghouses, boilers, engines, heaters, incinerators, lime kilns, regenerative thermal oxidizers, turbines, and many more — all of which require testing for air quality compliance.

While these industries must comply with the government standards for air testing, they do have options when it comes to choosing a stack testing company. There are many factors to consider when choosing a stack testing company, and we’ve set out to bring you the Top 12 Things To Look For in a Stack Testing Company.

1. QSTI Certified – The Source Evaluation Society (SES) has developed the Qualified Source Testing Individual (QSTI) program to ensure that stack testing companies can demonstrate knowledge and the ability to apply source testing methods as well as fundamental engineering and chemistry principles in a consistent and professional manner.

2. ISO Compliant (QA Program) – Compliance with the Source Emission Testing Quality Assurance Program helps ensure the validity of the data generated in the course of operations.

3. NELAC Accredited – Accreditation with the National Environmental Laboratory Accreditation (NELAC) Institute (TNI) ensures that the stack testing company meets the national standard for generating environmental data.
