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.

Iso 7 cleanroom standards.
In the uk british standard 5295 is used to classify cleanrooms.
This standard applies in general to all cleanrooms.
The particles range in size from 1 5 microns µm.
Classification for cleanrooms ranges from iso 1 to iso 9 with iso 9 being the dirtiest and iso 1 being the cleanest these classifications are assigned based on the maximum allowable concentration of particles per cubic foot or meter of air.
Only particle populations having cumulative distributions based on threshold lower limit particle sizes ranging from 0 1 µm to 5 µm are considered for classification purposes.
