ISO/DIS 14644-3 specifies performance tests for unidirectional and non-unidirectional cleanrooms in the three standard occupancy states (as-built, at-rest, and in operation).
There are many tests covered by the ISO/DIS14644-3;
- Air pressure difference
- Airflow direction and visualisation
- Temperature and humidity
- Installed filter system leakage
- Containment leak
- Electrostatic and ion generator
- Particle deposition
The test performed will depend on the features of your room.
