What is a cleanroom certification?

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
• Airflow direction and visualisation
• Recovery
• Temperature and humidity
• Installed filter system leakage
• Containment leak
• Electrostatic and ion generator
• Particle deposition
• Segregation

The test performed will depend on the features of your room.
