For industries with specific contamination control requirements, the standard can be applied alongside other regulatory frameworks:
Often called the "DOP" or "PAO" test, this confirms that HEPA/ULPA filters are properly installed and free of defects.

This widespread adoption often leads to users encountering "2020" or "2021" on their local standards body websites, although the underlying technical content is the ISO 14644-3:2019 standard (with the 2020 technical corrigendum). iso 146443pdf 2021
The first part of the standard (ISO 14644-1:2021) provides an overview of the cleanroom concept, basic principles, and requirements for cleanrooms and associated controlled environments. This part of the standard:
: The official document specifies test methods for designated classification of air cleanliness and for characterizing the performance of cleanrooms. You can find technical summaries on the Camfil Insights page HEPA Filter Validation
– The required upstream concentration for filter integrity testing was updated based on modern instrument capabilities. This allows more efficient testing without reducing leak detection sensitivity. | PDF delivery within 5 minutes; US pricing
This comprehensive guide details the mechanics of the 2021-adopted standard, explaining why organizations rely on it to secure regulatory approvals and how to execute its core test methodologies. The Evolution of ISO 14644-3
If you have typed into a search engine, you are likely part of a critical industry—pharmaceuticals, biotechnology, medical devices, aerospace, or semiconductor manufacturing. You need the most current version of the international standard for cleanroom testing.

– ISO 14644-3 requires specific documentation for each test, including apparatus calibration certificates, test conditions, raw data, and calculated results. Missing documentation is a common reason for regulatory observations.
ISO 14644-3 covers physical/particulate tests. ISO 14698 covers biocontamination (viable microorganisms). Many cleanrooms must comply with both.
