Problems of completion acceptance of clean projects:

First, after the construction of clean engineering in the completion of acceptance, should be carefully checked to prepare for acceptance of the data, generally including the following documents and records:

1. Record of joint review of drawings, notice of design change and as-built drawings;

2. Ex-factory qualification certificate and in-site inspection report of the main equipment, materials and instruments of each division project;

3. Installation and inspection records of stand-alone equipment and system of each branch project;

4. Record of single test run of each division;

5. Records of no-load test and debugging of each branch project and system;

6. All kinds of pipeline test and inspection records;

7. Inspection and commissioning records of safety facilities of each branch project;

8. Quality acceptance records of each branch project.

Two, the main test content of clean project completion acceptance is as follows:

1. Visual measurement of airflow;

2, wind speed and air volume test;

3. Leak detection of air filter;

4, clean room (area) airtightness test;

5. Static pressure difference test between rooms;

6. Air cleanliness level;

7. Self-cleaning time;

8, temperature, relative humidity;

9. Illuminance value;

10 noise level;

Other testing items required by the construction party.

Three, the completion of the clean project acceptance, and after verification and approval, according to the requirements for functional acceptance, functional acceptance is in the "static" test, the main test content is as follows:

1. Test the air cleanliness level;

2. For those who have requirements for the production process, microbial test or chemical contaminant test or special surface cleanliness test should be carried out;

3, clean room (area) temperature, relative humidity stability test;

4. Detecting self-cleaning time;

5. Test the airtight test of the clean room (area);

6. Determination of illumination;

7. Determination of noise level;

8. Confirm and record air flow form and air change times when necessary;

9. Other required testing items.

Four, after the use and acceptance of clean engineering, the use and acceptance report should be prepared, the main content of which is:

1. Open state description of various facilities (including production process equipment) in clean engineering;

2. The description of the personnel in the clean room (area) and their activities;

3. Separate test records and analysis opinions (including test point positions, coordinates, etc.);

4. Valid calibration certificate of the test instrument;

5, the acceptance of clean engineering to issue relevant conclusions.
