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 new standards, the first document of ISO 14644 was published in 1999, ISO ...
A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
FED-STD-209 E Airborne Particulate Cleanliness Classes in Cleanrooms and Cleanzones was a federal standard concerning classification of air cleanliness, intended for use in environments like cleanrooms. The standard based its classifications on the measurement of airborne particles. [1]
Cleanroom suitability describes the suitability of a machine, operating utility, material, etc. for use in a cleanroom, where air cleanliness and other parameters are controlled by way of technical regulations in accordance with ISO 14644.
The forceful "cleansing" of surfaces before entering clean environments reduces the number of airborne particulates introduced. [1] [2] When properly incorporated into cleanroom design, air showers provide an ISO-classified transition vestibule to ensure the cleanliness of the classified cleanroom.
"The Clean Room", a TV series episode; Cleanroom suit, overall garment worn in a cleanroom; Cleanroom mat, mat with an adhesive surface that is placed at the entrances or exits; Clean-room design, the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights associated with the original design
A cleanroom suit, clean room suit, or bunny suit, [1] [2] is an overall garment worn in a cleanroom, an environment with a controlled level of contamination. One common type is an all-in-one coverall worn by semiconductor and nanotechnology line production workers, technicians, and process / equipment engineers.
The basic principles of the cleanroom process are Software development based on formal methods Software tool support based on some mathematical formalism includes model checking, process algebras, and Petri nets.
