Iso class standards outline a higher degree of micron level particulates starting at 0 1 micron while fs 209e.
Iso 14644 cleanroom standards.
Maximum allowable concentrations by cleanroom class.
Discover the different classes within the cleanroom iso standards and their federal standard and gmp equivalent.
This part of iso 14644 specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones.
The federal standard provides an imperial measure of units particles per cubic ft while iso standards use metric units particles per square meter.
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.
5 48 typically measured micron sizes.

Whereas cleanliness standards were once defined by the federal standard 209e they have been replaced and simplified by iso with classifications 1 to 9.
Iso 14644 replaced the previous cleanroom standard federal standard 209e in 2001.
After ansi and iest petitioned to iso for new standards the first document of iso 14644 was published in 1999 iso 14644 1.
See our cleanroom classifications page.
Iso 14644 standards were first formed from the us federal standard 209e airborne particulate cleanliness classes in cleanrooms and clean zones.
