Clean Room Standards

The cleanroom classification standards fs 209e and iso 14644 1 require specific particle count measurements and calculations to classify the cleanliness level of a cleanroom or clean area.

Clean room standards.

Cleanrooms are rated based on the number of particles they can handle. Cleanroom classification particle count. Positive pressure keeps new particles from entering the clean area. In the uk british standard 5295 is used to classify cleanrooms.

The basis of cleanroom standards is the micrometer or micron for short µm which is the size of the particles to be filtered. Generally speaking a clean room is an enclosed room that has equipment which controls the amount of particulate matter in the air by using air pressure and filters. Cleanroom markets applications overview biotech cleanrooms nanotech cleanrooms cleantech cleanrooms university cleanrooms government cleanrooms. To meet requirements of a clean room as defined by federal standard 209e and newer iso standards all clean rooms must not exceed a particulate count as specified in the air.

When people are added to the matrix particulate levels rise still further in the operational cleanroom. As built at rest and operational. A cleanroom or clean room is a facility ordinarily utilized as a part of specialized industrial production or scientific research including the manufacture of pharmaceutical items integrated circuits crt lcd oled and microled displays. What makes a clean room a cleanroom.

Common applications are medical devices pharmaceutical and semiconductor manufacturing. As instruments and equipment are introduced and particulates rise an as built cleanroom becomes an at rest cleanroom. Cleanrooms are designed to maintain extremely low levels of particulates such as dust airborne organisms or vaporized particles. To some extent iso 14644 cleanroom standards.

Cleanrooms are used for manufacturing where high levels of cleanliness and sterility are required.
