When cleanrooms are put into use, there are 3 states below:

There are 2 types of static state of cleanroom

Static A: refers to the state in which the cleanroom has been installed and fully functional, the production equipment has been installed, and there is no personnel in cleanroom.

Static B: refers to the clean room after all production operations are completed. The production operators are evacuated from the site, and there is 20-minute clean-up time.

2. As-built cleanroom

As-built refers to the state of a newly built cleanroom. As-built cleanroom is fully functional and ready for operation. It is operationally qualified at the time it is handed over to the end-user.
