Dear Contamination Control Professional:
Final Draft of ISO 14644-6 Available!
The Institute of Environmental Sciences and Technology (IEST) announces that the Final Draft International Standard (FDIS) version of International Organization for Standardization (ISO) Standard 14644-6 Cleanrooms and controlled environments, Part 6: Vocabulary is now available through the Institute of Environmental Sciences and Technology (IEST). This FDIS document is an indispensable resource for anyone operating a cleanroom or controlled environment.
ISO/FDIS 14644-6 is an up-to-date, international dictionary of all cleanroom terms and definitions used in the ISO 14644 Cleanrooms and controlled environments and the 14698 Biocontamination series. Each definition is followed by the Standard designation and section 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 1992to address a need for global cleanroom standards rather 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 14644-9 Classification of surface particle cleanliness, were added to the program. The cornerstones of the series are Part 1: Classification of air cleanliness and Part 2: Specifications for testing and monitoring to prove continued compliance with
ISO 14644-1.
Working Group 6 of ISO/TC 209 was responsible for the harmonization and unification of the terms, definitions, and units within ISO Standard series 14644 and 14698, as well as for the harmonization with internationally used definitions. The task was difficult because of the multilingual and multidisciplinary character of the work.
The 34-page FDIS 14644-6 is available online at http://www.iest.org/iso/iso6.htm or by calling (847) 255-1561.
