Cleanroom Assessments

Cleanrooms, by definition, are designed to control airborne particulate and environmental conditions. Cleanrooms can be positive or negative pressure environments that sweep a specified area with HEPA filtered air.


Cleanrooms, by definition, are designed to control airborne particulate and environmental conditions. Cleanrooms can be positive or negative pressure environments that sweep a specified area with HEPA filtered air. Critical pharmaceutical, microbiological, and nanotechnological areas require adherence to exacting performance requirements. Our certification programs verify that your facilities perform to appropriate standards and specifications. Included with all testing is complete documentation of the test results and certification of the rooms and devices tested. An optional, customized formal report detailing test procedures, test results, and comprehensive conclusions of the testing performed can be included to suit your needs.

Our primary cleanroom testing battery includes:

  • Airflow volume and velocity readings - assures that both unidirectional and non-unidirectional flow areas are properly balanced and unidirectional zones are maintaining proper air patterns
  • Room air exchange rates - states if the area is meeting its design airflow
  • HEPA filter integrity testing - tests HEPA filters and system for leaks
  • Non-viable particle counting - reports the amount of airborne particulate of a specified size in the clean zone
  • Temperature / relative humidity testing - examines whether the air HVAC controls are functioning properly and uniformly
  • Pressure cascade monitoring - verifies that room differential pressures are operating according to design

Optional tests include:

  • Air balancing - adjusts airflow in the air handling systems to achieve design airflow, room air exchange rates, and pressure cascade
  • Airflow visualization testing – qualitatively verifies airflow direction using a source of visible fog
  • Viable environmental monitoring [EM] - samples both the air and surface for microbe enumeration and identification
  • Compressed gas testing [compressed dry air (CDA) testing] – assures that the compressed gas sources meet the requirements of the controlled environment for contamination and microorganisms
  • Lighting, vibration, and sound tests – assures worker comfort
  • All other special tests from the ISO/IEST guidelines
