ISO 14644-6 was originally published in 2007 to establish a unified vocabulary of terms and definitions for cleanrooms and associated controlled environments. It acted as a compendium, harmonizing definitions used across the various other parts of the ISO 14644 and ISO 14698 series. Key aspects of this standard included: In industries where microscopic contamination can lead to
