ISO 14644-3:2019 (Current Version) – Draft Post ISO 14644-3:2019
ISO 14644-3:2019 is the current standard for testing cleanroom performance, covering procedures for airflow, filter integrity, and pressure. Reports generated to these standards include assessments of airflow velocity, leakage, and environmental controls like temperature and pressure.

The standard provides a comprehensive set of test methods to characterize the performance of cleanrooms and clean zones. It ensures they meet specific air cleanliness classifications and other controlled conditions. Key Content and Test Methods
As of 2025 (this article’s current context), the 2019 version remains valid. ISO standards are typically reviewed every 5 years. Therefore, a revision (ISO 14644-3:2025 or 2026) is possible but not yet published.
- Cleanroom: A controlled environment with a specified level of airborne particulate contamination.
- Controlled environment: A defined space with controlled environmental conditions.
- Airborne particulate contamination: The presence of particles in the air that may affect the quality of products or processes.
