There are three ways to confirm the cleanliness of clean room, which are empty acceptance, static acceptance and dynamic acceptance. Empty acceptance refers to that the clean room facilities have been completed, but the production equipment has not been installed, and there is no flow of materials and personnel. The static acceptance facilities have been built, and the production equipment has been installed and put into operation, but there are no production personnel. The facility has been operated in accordance with the specified conditions and there are specified personnel present.
After that, there is only a three-level acceptance test. However, it is not standard and accurate to only do the acceptance of the foundation.
The completion acceptance of clean room shall be carried out after the appearance inspection, single machine test run, system joint actual operation, clean room performance test and adjustment under empty or static conditions, and relevant construction vehicle inspection records.
All kinds of pipes, automatic fire extinguishing devices and purification air conditioning equipment, air conditioners, fans, purification air conditioning units, high efficiency air filters and air shower rooms shall be installed correctly, firmly and tightly. The connection between high and medium efficiency filter and air duct and between air duct and equipment shall be reliably sealed. All kinds of regulating devices should be tight, flexible and easy to operate. Clean air conditioner, static pressure box, air duct system and air supply and return outlets without dust. The interior wall, ceiling surface and floor of the clean room should be smooth, flat, uniform in color, free from dust, and the floor should be free of static electricity.
All kinds of distribution boards and cabinets in the clean room and the electrical pipeline orifices entering the clean room shall be reliably sealed. After the single machine operation is qualified, the normal combined test run of the system with cold (heat) source must be carried out, which shall not be less than 8h. The linkage operation of various equipment components in the system must be coordinated, the action must be correct, and there is no abnormal phenomenon.
After the use acceptance of clean room, the use acceptance report should be prepared, which mainly includes:
1. Description of opening status of various facilities (including production process equipment) in clean room;
2. Description of the clean room (area) personnel tested and their activities;
3. Itemized test records and analysis opinions (including test point location, coordinates, etc.);
4. Valid calibration certificate of test instrument;
5. Relevant conclusions should be issued for the acceptance of clean room.
