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.
Whereas cleanliness standards were once defined by the federal standard 209e they have been replaced and simplified by iso with classifications 1 to 9.
The class defines a minimum cleanliness level not a specific design.
In the uk british standard 5295 is used to classify cleanrooms.
Cleanroom design and construction.
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.
This part of iso 14644 specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones.
Cleanroom requirements and standards provide a direct and easy to understand way of detailing the differences between the eight classes of cleanrooms.

Iso 14644 1 and older standard fs 209e determine class by the concentration levels of particles.
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.
Cleanrooms are rated based on the number of particles they can handle.

What exactly is cleanroom classification.
They range from an iso class 1 cleanest to an iso class 8 least clean.
Simply speaking for iso 14644 1 classification threshold particles of 0 1 microns to 5 microns in size are considered.

Methods for evaluating and measuring cleanrooms and associated controlled environments.
This standard applies in general to all cleanrooms.
The federal standard 209e is used domestically and the standard tc 209 established by the international standards organization is recognized.
Cleanroom testing for compliance.
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.
