Iso Class 8 Clean Room

The cleanroom class is the level of cleanliness the room complies with according to the quantity and size of particles per volume of air.

Iso class 8 clean room.

However class will greatly impact design considerations such as filtration hvac requirements and other design elements. A cleanroom must have less than 35 200 000 particles 0 5 micron per cubic meter and 20 hepa filtered air changes per hour. Considerations for iso class 8 cleanrooms. Iso 8 class 100 000 0 005 0 041 1 8 5 48.

Iso clean room classifications are rated according to how much of a particulate of a specific size exists per cubic meter within a given enclosure see second chart. The lower the iso class the more stringent the requirements for keeping particles and contamination to the acceptable levels of the room class. Iso 7 class 10 000 0 051 0 076 10 15 60 90. High efficiency particulate air hepa filtration is 99 99 efficient at 0 3 micron and should be considered when looking to achieve iso class 8.

Fs209e features six classes while the iso 14644 1 added two cleaner and one dirtier standard. Classification is based on the amount of specific sized particulates per cubic metre. 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. The particles range in size from 1 5 microns µm.

Iso 8 is the least clean cleanroom classification. Monobloc panel hardwall and softwall cleanroom envelopes are all effective at achieving the environment required for iso class 8. Iso class 8 equals class 100 000 under fs209e. Class 1 is the cleanest cleanroom in fs209e while class 9 is the dirtiest.

First the amount of air is different in an iso 6 and in an iso 8. Iso 14644 1 and older standard fs 209e determine class by the concentration levels of particles. Remember the air is 100 times cleaner in an iso 6 than in an iso8. Class iso 146144 1 federal standard 209e average airflow velocity m s ft min air changes per hour ceiling coverage.

In reality however you can reach an iso 6 clean room with 1 recommendation is 2 airlock. Clean room classifications are based on an eight class rating system with an iso class 1 cleanroom being rated the most particle free and iso class 8 allowing the most particles. The class defines a minimum cleanliness level not a specific design. A non hazardous sterile compounding cleanroom or a hazardous sterile compounding cleanroom in negative pressure are not the same price.

The equivalent fed standard is class 100 000 or 100 000 particles per cubic foot. Iso 8 iso 7 iso 6 iso 5. An iso 6 and an iso 8 cleanroom are not the same price per square foot. By comparison a typical office space would be 5 10 times more dirty.
