Cleanroom Certification Services

Unified Cleanroom Construction can provide certification of our cleanrooms to ensure that the project meets the owner’s requirements as originally specified either in the design build plan and specifications or cleanroom envelope situation. Unified Cleanroom Construction provides third party independent certification of the cleanroom. Typically cleanrooms are tested in accordance with ISO standard 14644 but other testing requirements may be crucial and be specified. These include temperature and humidity control, lighting levels, sound levels, leak checking, particulate levels, uninterrupted air flow, air flow velocity, molecular contamination, biological contamination, electro static levels, pressure, and conductive requirements. Depending on the project and requirements of the project Unified Cleanroom Construction can certify these and provide the third party certification.

ISO Standard Cleanroom Classification

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Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones, on November 29, 2001 and FED-STD-209E was then superseded by ISO 14644-1 and ISO 14644-2.

In December 2010, revisions of ISO 14644-1 and -2 were released as Draft International Standards.
