Iso Clean Room Specifications
The amount stipulated for each cleanroom application depends on the class of air cleanliness required.
Iso clean room specifications. So for example an iso class 5 cleanroom has at most 10 5 particles m 3. Iso class 1 the cleanest cleanroom is iso 1 used in industries such as life sciences and electronics that require nanotechnology or ultra fine particulate processing. It could be about making a product managing a process delivering a service or supplying materials standards cover a huge range of activities. So for example an iso class 5 cleanroom has at most 105 100 000 particles per m.
For iso class 8 particles smaller than 0 5 µm aren t considered. The concentration of particles that are 0 5 µm should be below 3 520 000. Iso standards are internationally agreed by experts. A cleanroom must have less than 3 520 particles 0 5 micron per cubic meter and 250 300 hepa filtered air changes per hour.
Iso cleanroom specifications iso 5 is a super clean cleanroom classification. The international organization for standardization iso says that clean rooms must not exceed a certain particulate count measured in cubic meters. This is one of the most common classes of cleanrooms. Iso 8 zone 15 25 air changes per hour ante room.
Iso 14644 1 and older standard fs 209e determine class by the concentration levels of particles. 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. Iso 8 cleanroom particle specifications. If you need an iso 7 cleanroom you should consider having an iso 8 airlock gowning room prior to entering the iso 7 room.
The class defines a minimum cleanliness level not a specific design. In federal standard 209 a to d of the usa the number of particles equal to and greater than 0 5mm is measured in one cubic foot of air and this count is used to classify the cleanroom. 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 cubic metre of air. The air changes per hour will vary in both rooms as described below.
Think of them as a formula that describes the best way of doing something. Both fs 209e and iso 14644 1 assume log log relationships between particle size and particle concentration. The particles range in size from 1 5 microns µm. Iso cleanroom standards clean rooms are classified by how clean the air is.
