A cleanroom must have less than 35 200 000 particles 0 5 micron per cubic meter and 20 hepa filtered air changes per hour.

Iso 14644 cleanroom classification table classes and requirements.
D recommended air changes per hour ach.
Federal standard 209e equivalent.
The equivalent fed standard is class 100 000 or 100 000 particles per cubic foot.
Small numbers refer to iso 14644 1 standards which specify the decimal logarithm of the number of particles 0 1 μm or larger permitted per m 3 of air.
5 48 typically measured micron sizes.
Iso 6 cleanroom class 1 000 in theory for an entire room to reach iso 6 air cleanliness you need to enter the cleanroom via an iso 8 ante room then go through an iso 7 to finally get into the iso 6 as shown in the image.
Maximum allowable concentrations by cleanroom class.
Iso 8 clean rooms do not require certain particle sizes to be tested either because concentration levels are too high or low to be tested but it cannot be zero.
Cleanrooms are rated based on the number of particles they can handle.
See our cleanroom classifications page.
Discover the different classes within the cleanroom iso standards and their federal standard and gmp equivalent.
Iso is an independent non governmental international organization with a membership of 162 national standards bodies.
Both fs 209e and iso 14644 1 assume log log relationships between particle size and particle concentration.
These tables detail the air changes and particle counts that define each class.
Through its members it brings together experts to share knowledge and develop voluntary consensus based market relevant international standards that support innovation and provide solutions to global challenges.
Federal standard 209e cleanroom standards for iso an older standard.
So for example an iso class 5 cleanroom has at most 10 5 particles m 3.
In reality however you can reach an iso 6 clean room with 1 recommendation is 2 airlock.
Considerations for iso class 8 cleanrooms.
Iso 8 cleanroom particle specifications.
Information on iso 14644 1 2015 class 8 cleanroom classification.
The concentration of particles that are 0 5 µm should be below 3 520 000.
Cleanroom requirements and standards provide a direct and easy to understand way of detailing the differences between the eight classes of cleanrooms.
Class 100 000 associated eu gmp grade.
They range from an iso class 1 cleanest to an iso class 8 least clean.
In the uk british standard 5295 is used to classify cleanrooms.
For iso class 8 particles smaller than 0 5 µm aren t considered.
