February 20, 2008 — /ARLINGTON HEIGHTS, IL/ — International Organization for Standardization (ISO) standard 14644-6, cleanrooms and controlled environments part 6, vocabulary has been approved as an American national standard. The standard is available through the Institute of Environmental Sciences and Technology (IEST).

ISO 14644-6 is an up-to-date, international dictionary of all cleanroom terms and definitions used in the ISO 14644 cleanrooms, controlled environments, and the ISO 14698 biocontamination series. This document is a great library resource for official definitions regarding cleanrooms and associated controlled environments, particularly in contract negotiations between buyers and sellers.

Each definition is followed by the Standard designation(s) and section(s) in which it is used. An index makes finding a particular definition easier.

ISO established Technical Committee (TC) 209 cleanrooms and associated controlled environments in 1992 to address a need for global cleanroom standards other than the collection of differing national standards in place at that time. ISO 14644-6 is the last document of the original list proposed by ISO/TC 209 in 1992. Since that time, two
additional documents, ISO 14644-8, classification of airborne molecular contamination, and ISO 14644-9, classification of surface particle cleanliness, were added to the program. The cornerstones of the series are ISO 14644-1, classification of air cleanliness, and ISO 14644-2, specifications for testing and monitoring to prove continued compliance with ISO 14644-1.
