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.
