HEPA filter integrity testing

To reach the desired cleanliness level, the achievement of Airflows is essential.  We offer highly trained personnel to check that your engineers have achieved your design values within Clean Rooms,  including balancing advice and guidance which will help you ensure that you comply with your URS/RDS and that the HVAC is running cost effectivly for your Clean Room.


The Commissioning process starts once the Clean Room installation is completed and assesses the design completion in terms of requirements, performance, operation and maintenance.


Several tests are performed during the commissioning including:

Installation Qualification ensures that the installation of the equipment is accurate by comparing th existing system against the design and the manufacturer’s specification. It provides a complete documentary record of the installation.


The objective of the Operation Qualification is to check those operational aspects of the HVAC system that are deemed critical to its satisfactory performance and compare the data obtained with approved specification and current GMP.  Prior to this, it should be confirmed that all critical instrument have been calibrated for performing the OQ test.


The Performance Qualification is undertaken once the OQ has been completed within the time specified between the clients and ourselves.  Not all tests undertaken in the OQ need to be retested for the PG, only those tests deemed critical and which can show that the system can run within the design criteria on a continuous basis.  For PQ tests it is essential to demonstrate that the process or equipment performs as intended in a consistant manner over time.


Re-Qualification tests for cleanrooms are undertaken after a period of operation. They are conducted in order to prove that there is continued compliance between the Clean Room performance and the desighn specification and standards.The time period after which re-qualification tests need to be undertaken are defined in ISO14644-2. Clean Rooms 


A Filter Interity Testing and Particle Counting test program is required to confirm if the classification of the Clean Rooms remains within the specified ISO classification.


The test frequency should be determined by a risk assessment of the operations within the cleanroom, however they typical frquency is: 

  • ≤ ISO 5 retest every 6 months

  • >ISO 5 retest every 12 months


Typically the Airflow Volume and the Air Velocity should be confirmed at least once every 12 month period.


The Differential pressures shall be confirmed at least once every 12 month period.
