Cleanroom commissioning and independent handover testing
Before a new or refurbished cleanroom is used, you need independent proof that it was built and performs as designed. Our commissioning tests give you that evidence at handover, so problems are fixed by the installer rather than discovered later.
From construction to first use
A cleanroom project ends with a handover, but handover is only meaningful if the room genuinely performs. Commissioning tests compare the as-built room with its design specification and identify gaps while the contractor is still on site to correct them.
Commissioning normally takes place in the as-built state, when the room is complete with services connected but before production equipment and people move in. Tests are later repeated at-rest once equipment is installed, as part of clean room qualification.
Independent testing matters. Results from a third-party, accredited laboratory carry more weight than the installer's own tests, and they give you an impartial baseline for every future clean room certification.
We work alongside your project team, HVAC contractor and quality department to plan testing, report findings clearly and retest after corrections.

Fix problems before production starts
Lower rework cost
Defects found at handover are corrected by the installer, not at your expense later.
Faster qualification
A well-commissioned room moves smoothly into qualification and use.
Reliable baseline
Commissioning data becomes the reference for all future testing.

Planning commissioning in your project
Build commissioning into the project timeline from the start. Testing needs the HVAC system running and balanced, filters installed, doors fitted and penetrations sealed. Leave time after testing for corrections and retests before the planned start of production.
Share design documents early: room classes, air volumes, pressure differentials and temperature and humidity ranges. These form the acceptance criteria that commissioning results are measured against.
What commissioning often finds
Typical findings include filter gasket leaks, unbalanced air volumes, reversed or weak pressure cascades, unsealed service penetrations, doors without effective closers and temperature or humidity outside design. Most are simple to fix during the project, but expensive and disruptive once the room is in production. Read our cleanroom commissioning guide for more detail.
What the commissioning report includes
The commissioning report lists every room, its design values, the instruments used and their calibration status, measured results, deviations found, corrective actions and retest results. It becomes the baseline document for qualification and every future certification, so it is worth getting right at handover.
Keeping drawings, design data and commissioning results together in one file also makes later modifications easier to plan and verify.
Roles during commissioning
Commissioning works best when the project manager, HVAC contractor, quality team and testing laboratory agree responsibilities in advance. The contractor prepares and balances the system, the laboratory tests independently, and the quality team reviews results against design. Clear roles prevent delays at handover.
How the work is carried out
Design review
We review drawings, room classes and design values to set acceptance criteria.
As-built testing
Filters, airflow, pressure, cleanliness and conditions are tested room by room.
Findings and retest
Deviations are reported for correction, then retested.
Commissioning report
A complete report documents the room's performance at handover.
