: It outlines the procedures for testing cleanrooms to characterize their performance. : It is often used during the initial qualification of a cleanroom and for periodic re-testing to ensure ongoing compliance.
A popular source for technical standards.
ISO 14644-3:2019 specifies the requirements for the testing and certification of cleanrooms and associated controlled environments. The standard covers the following aspects:
The facility is functioning in its normal state with equipment and personnel active. Key Performance Tests
Hi everyone,
Reference lists for required apparatus (like particle counters and anemometers) are typically found in Annex C of the standard. specific test procedure
Verifies that the pressure inside the cleanroom is higher than adjacent areas to prevent infiltration of contaminants.
The ISO 14644-3 standard does not define cleanroom classification levels—which are governed exclusively by ISO 14644-1 . Instead, Part 3 acts as the operational engineering manual. It details exactly how to measure parameters like pressure differentials, airflow velocity, recovery rates, and filter leaks.
This ensures you have the complete, correct, and most up-to-date version, which includes the corrected version released in June 2020. Do not rely on free, unofficial copies found online, as they may be out-of-date, incomplete, or inaccurate.
Demonstrating the path of airflow to ensure no dead zones exist where contamination can accumulate.
The ISO 14644 standard is not a single document; it's a comprehensive series of parts, each addressing a specific aspect of cleanroom technology. The following table summarizes the current and upcoming parts along with a brief description of their focus:
for characterizing and measuring the performance of cleanrooms and associated controlled environments. While ISO 14644-1 focuses on the classification of air cleanliness, Part 3 details
