ISO 14644-3:2019 (often adopted as 2021 standards) provides essential test methods for cleanroom performance verification, focusing on air pressure, airflow, and recovery tests across various occupancy states. The revision simplifies filter leakage testing, removes classification guidance, and introduces specialized tests for segregation and recovery, serving as a critical guideline for regulatory compliance. For the full technical details, refer to the ISO Online Browsing Platform ISO - International Organization for Standardization

Introduced in the 2019 revision, this test evaluates the ability of the cleanroom to prevent contamination from leaking between two adjacent areas of different cleanliness levels. Significant Updates in the Latest Revision The shift from the original 2005 version to the ISO 14644-3:2019 iso 146443pdf 2021

Upcoming Changes and Future Developments:

• Particle counter (annual NIST-traceable calibration).
• Anemometers and manometers (12–24 months).
• Photometers (for filter leakage – every 12 months).
