Changes are coming...be the first to know about the latest ISO 14644 Cleanroom Standards revisions! Click here to receive e-mail updates about new and revised ISO 14644 Standards.
ISO 14644 Standards were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. The need for a single standard for cleanroom classification and testing was long felt. After ANSI and IEST petitioned to ISO for a new standard, the first document of ISO 14644 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Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones, on November 29, 2001 and FED-STD-209E was then superseded by ISO 14644-1 and ISO 14644-2.
