Our Testing Process for Clean Rooms

Our Testing Process for Clean Rooms

We undertake the testing and commissioning of cleanrooms in accordance with international standards and customer quality specifications. Cleanroom test protocols and report documentation can be customised to customer specifications.

Our most popular types of cleanroom testing include:

  • Room pressurisation monitoring
  • Non-viable particulate monitoring
  • HEPA filter integrity testing
  • Airflow volume/velocity profiling
  • Room air exchange rates
  • Temperature and humidity monitoring

To ensure that your clean room environment is working effectively a number of factors relating to the air supply coming from your ventilation need to be tested. These tests apply to every type of clean room, whether used for the manufacture of pharmaceutical products, sterile and aseptic or food production.

We also need to test the flow of the air to ensure that it is moving from clean to less clean areas, minimising the movement of any contaminated air into your clean area, and also to ensure there are no areas of the room with high concentrations of pollutants.

Clean Room Testing and Commissioning

In order to carry out these tests, for every clean room we are working in, we will measure and check:

  1. Air Tightness Testing – to check your room envelope is air tight and not leaking.
  2. Air Supply and Extract Quantities – If your air supply is unidirectional we will measure and record the air velocity.
  3. Differential Pressure – Here we will be testing to ensure that the air in your clean room always moves from clean to less clean areas.
  4. Filter Installation Leak Testing – Your ventilation system’s high efficiency particulate air (HEPA) filter can be tested to ensure their integrity.
  5. Containment Leak Testing – We will check the construction of your clean room to ensure that no airborne contamination can occur via leaks from higher pressure work areas adjacent to it.
  6. Air Movement Control – Studying the movement of the air within your clean room we will check that there is sufficient air movement to dilute or remove pollutants, preventing any contamination build-up.
  7. Room Recovery – Reviewing the effectiveness of airflow we will measure how quickly a clean room recovers to its normal operating cleanliness following a release of particulate contaminant.
  8. Airborne particles and microbial concentrations – Finally, we will carry out measurements to ensure that the concentration of particles and micro-organisms is compliant with the specification set out for your clean room.
  9. Temperature, Relative Humidity – We may also need to carry out tests on temperature, relative humidity, and the heating and cooling capabilities of the room, as well as noise, lighting and vibration levels.

If you have a clean room that requires particulate monitoring or any of the above testing then please get in touch with us as soon as possible as we should be able to offer you an expedient solution for your cleanroom testing and cleanroom certification.

We can also offer maintenance programmes to ensure your cleanroom is in compliance with the corresponding ISO standards– it’s why we place such emphasis on the process of ‘expert intervention’.
