Clean rooms are classified according to the cleanliness level of the air inside the controlled environment. The clean room class is the level of cleanliness the room complies with, according to the quantity and size of particles per cubic meters of air. The primary authority in the US ...
Under the FED STE 209E system, there was no equivalent for this level of cleanliness. Classification 9 is defined as room air. Not bad, but, sorry, not particularly clean. Limits and Limitations of ISO 14644 You should note that this standard does not consider particle populations outside ...

Conversely, an ISO 1 cleanroom classification must contain no more than 0.35 particles per cubic meter at 0.5 micron and larger. And an ISO 5 cleanroom classification (which is equivalent to class 100 from the retired-US FED Standard 209E) must contain no more than 3,520 particles per cubi...
