ISO 14644-3 outlines multiple tests to validate performance. These are divided into core tests and optional tests, based on the cleanliness class and purpose of the cleanroom. A. Airflow Volume and Velocity Test
Yes. ISO 14644-1:2015 remains the current active version for air cleanliness classification. No newer version has been published.
The ISO 14644 series forms the international foundation for cleanroom design, classification, and operation. The series includes multiple parts that cover the entire lifecycle: iso 146443pdf 2021
ISO 14644-3:2019 focuses on performance parameters that ensure a stable, contamination-controlled environment. The most critical tests include: Filter Integrity (Leak Testing):
Examples of these 2021 adoptions include:

Procedures for actual classification were moved entirely to ISO 14644-1 , leaving Part 3 strictly for supplemental test methods.
The structural facility is finished, utilities are operating, but no production equipment or personnel are present.
Understanding the nuances of this protocol is essential for cross-industry compliance, optimizing cleanroom life-cycles, and guaranteeing air purity. Key Roles and Purpose of Part 3
Equipment is installed and operating as agreed, but no personnel are present. No newer version has been published
: Measuring velocity and volume to ensure proper air change rates. Filter Leak Tests : Verifying the integrity of HEPA/ULPA filters. Recovery Tests
These tests are considered essential for the basic characterization of a cleanroom. If you are doing a classification, you are almost certainly performing these:
