High-purity water fog or chemical smoke is introduced into the cleanroom stream. The pattern is captured via video recording.

Compile the results into a validation report, essential for regulatory audits. 5. Summary of 2019 Revisions High-purity water fog or chemical smoke is introduced
While ISO 14644-1 focuses on classifying air cleanliness by particle concentration, Part 3 specifies the actual testing methodologies used to characterize and verify cleanroom performance. It outlines the physical tests required to analyze airflow, filters, containment integrity, and environmental variables. Core Test Methods Outlined in ISO 14644-3 Core Test Methods Outlined in ISO 14644-3 If
If you are writing a protocol based on ISO 14644-3, prioritize these three practical elements:
Often considered the gold standard for compliance, airflow visualization (also called smoke studies) provides visual proof of how air moves within the cleanroom. The test involves releasing ultrapure fog or smoke and recording its flow patterns using video.
