Requirements for materials used in the cleanroom [10] Maintaining the cleanroom environment in a clean, usable condition conforming to design standards. [10] This part was published as an International Standard in 2004. The document was submitted as an American National Standard and has been adopted as ANSI/IEST/ISO 14644-5:2004 in the United ...
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.
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.

Although the clean-room approach had been used as preventative measure in view of possible litigation before (e.g. in the Phoenix BIOS case), the NEC v. Intel case was the first time that the clean-room argument was accepted in a US court trial. A related aspect worth mentioning here is that NEC did have a license for Intel's patents governing ...

High-level HEPA filtration and increasing air changes per hour (ACH) can reduce particulate matter (PM) and bacterial concentrations in the operating room. [ 4 ] The Facility Guidelines Institute recommends using sequential HEPA filters for ORs with a MERV rating of 7 (i.e., captures particle 10 to 3 μm in size) and 14 (i.e., captures ...
