Description

The first document of the ISO 14644 series was published in 1999 (ISO 14644-1). In 2000, ISO 14644-2 was published, which began the process of FED-STD-209E being canceled. The U.S. General Services Administration (GSA) released a Notice of Cancellation for FED-STD-209E, Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones, on November 29, 2001 and FED-STD-209E was then superseded by ISO 14644-1 and ISO 14644-2.
