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.
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.

Depending on the type of product being manufactured the level of clean controlled space is initially determined using the cleanroom classification standards, the higher the risk of contamination the cleaner the environment, e.g., aseptic filling is performed in an ISO 5 controlled environment, whereas terminally sterilized product is finished ...
