: Measuring parameters like airflow volume, velocity, and pressure differences between zones.
ISO 14644-3:2021 provides a comprehensive framework for testing and evaluating cleanrooms and associated controlled environments. By following this standard, organizations can ensure that their cleanrooms and controlled environments meet the required standards for airborne particulate contamination. iso 146443pdf 2021

(commonly referenced in 2021 cleanroom validations) is the definitive guide for testing cleanroom performance. Its 2019 update introduced more rigorous, quantitative methods for airflow visualization and containment testing, reflecting industry needs for isolators and automated manufacturing. For anyone managing a cleanroom in 2021 or today, compliance with this standard ensures that classification (ISO 14644-1) is reliably verified and that operational parameters meet design intent.
Cleanrooms and associated controlled environments — Part 3: Test methods Published: 2021 Summary: This document provides test methods for evaluating the performance of cleanrooms and associated controlled environments. These tests are designed to verify the cleanliness, temperature, humidity, and other parameters that are critical to maintaining a controlled environment.
For cleanroom professionals who adopted the standard in 2021, your current validation protocols remain compliant until the next revision is released. However, monitor the (Technical Committee for cleanrooms) for upcoming draft amendments.
