Uses visual aids to demonstrate that the airflow pattern effectively removes contaminants from critical work zones.

This test measures the velocity of airflow within the cleanroom to ensure it meets design requirements for maintaining a controlled environment. iso 146443pdf

The text updated again:

This confirms that the cleanroom maintains the required pressure differential relative to adjacent, less-clean areas to prevent contamination ingress. 4. Airborne Particle Count Test Uses visual aids to demonstrate that the airflow

Cleanrooms and associated controlled environments are critical in contamination-sensitive industries like pharmaceuticals, medical devices, aerospace, and microelectronics. To ensure these environments function effectively, rigorous testing is essential. ("Cleanrooms and associated controlled environments - Part 3: Test methods") is the definitive international standard that outlines the required testing procedures to verify cleanroom performance. iso 146443pdf
