What is a clean room?
A “clean room” literally a room that is clean; however, it has a special meaning. It is a room whose air cleanliness is maintained and controlled according to specific standards and rules to ensure it does not affect the quality of the products to be manufactured.
Cleanliness is represented by the class of air cleanliness in controlled environments, such as Class 1 and Class 100. Each cleanliness standard has its own classification system.
|Cleanliness clas||number of particles with a diameter of - 0.5 µm or larger (the number of dust particles)|
