While ISO 14644-1 defines what "clean" means in terms of particle concentration, Part 3 describes how to measure it and other critical performance parameters. Its scope encompasses various testing methods for both unidirectional and non-unidirectional airflow systems. These tests are typically conducted across three occupancy states:
The series is an internationally recognized set of standards titled “ Cleanrooms and associated controlled environments. ” Developed and maintained by ISO Technical Committee 209 (ISO/TC 209), these standards provide detailed requirements for cleanroom classification, design, testing, operation, and monitoring. The 2021 updates demonstrate the ISO committee‘s ongoing
The ISO 14644 series represents the global gold standard for cleanroom classification and contamination control. The 2021 updates bring critical improvements, particularly the addition of ISO 14644-17 for particle deposition rate applications and the extensive revisions to parts covering separative devices, chemical concentration, and surface cleanliness.
Yes. ISO 14644-8 addresses airborne chemical concentration (ACC), and ISO 14644-10 addresses chemical contamination on surfaces. While ISO 14644-1 defines what "clean" means in
