They range from an iso class 1 cleanest to an iso class 8 least clean.
Clean room lighting requirements.
A cleanroom is an enclosed room equipped to control the levels of airborne particulate matter.
A clean room gmp cleanroom in my mind are a combination of engineering design fabrication finish and operational controls control strategy that are required to convert a normal room to a clean room.
Positive pressure keeps new particles from entering the clean area.
Continuous technological innovations have made the cleanroom industry dynamic and ever changing.
Cleanroom and containment lighting must be built to meet highly specialized environmental challenges.
What type of lighting to use for a cleanroom will depend on what is being constructed in the cleanroom its classification and its ceiling air supply configuration.
