Overview of the

ISO/TC 209 14644 Standards 

IEST serves as Secretariat for ISO/TC 209: Cleanrooms and associated controlled environments. The official, internationally approved versions of the ISO 14644 and 14698 Standards are available directly through IEST.

ISO/TC 209 is developing multi-part documents encompassing the standardization of equipment, facilities, and operational methods. The cornerstones of the standard are ISO 14644: Cleanrooms and controlled environments, Part 1: Classification of air cleanliness and Part 2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1.
