Iso 14644 1 cleanroom standards.
Whereas cleanliness standards were once defined by the federal standard 209e they have been replaced and simplified by iso with classifications 1 to 9.
Concentrations of ultrafine particles particles smaller than 0 1 µm will be addressed in a separate standard to specify air cleanliness by nano scale particles.
The need for a single standard for cleanroom classification and testing was long felt.
Iso 14644 standards were first formed from the us federal standard 209e airborne particulate cleanliness classes in cleanrooms and clean zones.

Simply speaking for iso 14644 1 classification threshold particles of 0 1 microns to 5 microns in size are considered.
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.
After ansi and iest petitioned to iso for new standards the first document of iso 14644 was published in 1999 iso 14644 1.
This standard includes the cleanroom classes iso 1 iso 2 iso 3 iso 4 iso 5 iso 6 iso 7 iso 8 and iso 9 with iso 1 being the cleanest and iso 9 the dirtiest class but still cleaner than a regular room.
