ISO 14644-1:2019 is the first part of the ISO 14644 series, which provides guidelines for the design, construction, and operation of cleanrooms. This standard was published in 2019 and replaces the previous version, ISO 14644-1:2006. The standard provides a framework for creating and maintaining cleanrooms, ensuring that they meet the required standards for cleanliness, temperature, humidity, and other environmental factors.
Recent revisions (specifically to Part 1) have introduced more rigorous sampling requirements: Sampling Points:
Understanding these definitions is necessary for compliance with ISO 14644-1 (classification) and ISO 14644-3 (testing).
Cleanrooms and associated controlled environments are critical to modern manufacturing, research, and healthcare. From producing microchips to formulating pharmaceuticals, these environments ensure that airborne particles, microorganisms, and chemical vapors are kept within strictly defined limits. The series of standards is the global benchmark for designing, operating, and maintaining these clean areas.
The standard ensures that definitions are aligned with current industry practices as of its publication. Scope of ISO 14644-6 iso 146446 pdf
Microorganisms that can contaminate a product or process. 3. Filtration and Airflow Terms
Filters represent a significant source of pressure drop. Selecting filters with lower pressure drop (while maintaining efficiency) reduces fan load. The standard suggests proper monitoring to ensure filters are changed based on pressure drop, rather than simply by a set time interval. 3. Energy-Efficient HVAC Components

The most reliable way to get the standard is to purchase it directly from an authorized standards body. The ISO 14644 PDF can be purchased from official sources such as:
ISO 14644 is a multi-part international standard developed by the International Organization for Standardization (ISO). It replaced outdated national standards—most notably the U.S. Federal Standard 209E—to harmonize cleanroom classification, testing, and monitoring worldwide. The standard applies to any environment where airborne particle concentration needs to be controlled, from semiconductor fabrication plants to operating rooms.
: This is the most widely cited part. It establishes the "ISO Classes" (Class 1 to Class 9) based on the concentration of airborne particles per cubic metre of air.
