New or renovated space
Establish baseline performance after construction, renovation, system modification or commissioning.
Installed-filter leak testing, documented findings and retest support.
Discuss This ServiceCleanroom certification should do more than produce a pass/fail certificate. A useful program establishes what is being tested, the room operating state, the acceptance criteria, the instruments and methods used, and how the results relate to your process and quality system.
Micron works with facility, engineering and quality teams to define a defensible scope before testing begins. Field results are organized so teams can distinguish an isolated test failure from a broader airflow, filtration, controls or operational issue—and decide what to do next.
Final methods and acceptance criteria depend on your facility, equipment, operating state and applicable requirements.
Understanding the surrounding system helps prevent a test result from being interpreted without the context needed to correct it.
Establish baseline performance after construction, renovation, system modification or commissioning.
Confirm that the room continues to meet the defined classification and performance requirements.
Evaluate pressure alarms, particle excursions, filter concerns or unexplained environmental trends.
Before the visit, we align the report contents with the people who will review it. This reduces ambiguity about tested conditions, acceptance criteria, deficiencies and retest status.

The interval depends on the governing standard, room classification, process risk, facility procedures and regulatory expectations. Periodic testing should also be reconsidered after significant system changes, filter replacement, construction or adverse trends.
No. ISO 14644-1 addresses classification by airborne particle concentration. A facility-specific certification scope may also include HEPA integrity, airflow, room pressure, recovery, temperature, humidity and other tests.
The agreed state—at-rest, operational or another defined condition—must be established before sampling. Occupancy, equipment operation and room preparation can materially affect the result.
