**Cleanroom Engineering Quality Standards – Shanghai Sujing**
Here are the key quality standards for cleanroom engineering projects by Shanghai Sujing. These guidelines ensure that all components, from partition walls to ducts and electrical systems, meet strict performance and aesthetic requirements.
1. **Hanging Codes**: The spacing of T-profile hanging codes should be less than 1.5 meters. FFUs (Fan Filter Units) and high-efficiency air supply outlets must each have four lifting points, and these must be securely fastened.
2. **Partition Walls**: Color steel plate walls must form a perfect 90-degree angle, verified using a square ruler. Upper and lower parts must be reinforced with slot aluminum. All joints must be tight and sealed with glass glue. For 90-degree connections between ceiling panels and side walls, angle aluminum (up to 80 cm in length) is required. Curved or straight edges should use tee fittings, top balls, or plugs. Any sockets, switches, or fire hydrants must be sealed with glass glue and look neat.
3. **Ceiling Panels**: The interface between color steel plates must be tightly sealed with glass glue. Joints should be reinforced with angle iron or aluminum, spaced no more than one meter apart. If there’s an opening, the damaged area must be replaced. Gypsum ceilings should be fully finished before installation.
4. **Outer Cylinder**: The outer cylinder must remain intact, clean, and properly wrapped in paper before delivery. It should be straight and undamaged.
5. **Color Steel Doors**: Door closers and locks must be secure, with no gaps. They should be sealed on all sides to prevent air leakage.
6. **Glass Observation Windows**: After installation, windows must be clean and free of vibration. Glass glue should be applied around the edges, and double-glazed windows must maintain a clean and neat appearance.
7. **High-Efficiency Filters**: Filter cores must be secured at all four corners, with no air leakage. This is confirmed using a laser particle counter. FFUs follow the same standard.
8. **Diffusers**: Diffusers must be cleaned before installation and wrapped in paper after.
9. **Pre-Acceptance Cleaning**: Before project acceptance, equipment like air showers and transfer windows must be cleaned, along with return air columns and walls.
10. **Site Hygiene**: Daily cleaning is required. Excessive waste must be reported to management for disposal. Materials should be neatly stacked, and loose screws, nuts, and rivets must be placed in designated areas.
11. **Electrical Box Switches**: Each switch must be clearly labeled.
12. **Power Supply Interfaces**: Fire, neutral, and ground wires must be marked by wire color or labeling tape.
13. **Wiring Integrity**: Wire skins must not be damaged or peeled.
14. **Wiring Layout**: Before construction, the layout of equipment and lighting lines must be discussed with company management.
15. **Pipe Clamps**: Pipe clamps must be used, and the number should not be reduced.
16. **Fittings**: Tees and elbows must be used for all pipe routes.
17. **Lighting and Equipment Wiring**: Before installation, wiring for lights and equipment must be coordinated with management.
18. **Floor Protection**: After flooring is complete, all workers must wear slippers inside the workshop and avoid stepping on color steel plates, ducts, or water pipes.
19. **Sealing Gaps**: Glass glue must be used to seal gaps between color steel plates and walls.
20. **Filter Sealing**: Glass glue must also be applied to the contact surfaces between high-efficiency filters and color steel plates.
21. **Circuit Diagrams**: All circuit diagrams must be completed according to drawings, with no shortcuts taken.
22. **Concealed Outlets**: Concealed switches and sockets must have conduit, and any gaps with color steel plates must be sealed.
23. **Final Inspection**: After color steel plate installation, check for installation issues, wiring short circuits, and material damage. Report any problems to Party A immediately.
24. **Door Installation**: Color steel doors must open and close smoothly, with flexible locks.
25. **Door Sealing**: Door joints must be sealed with vertical curtains.
26. **Opening Sealing**: Openings in color steel plates must be sealed with glass glue.
*(Note: All above refers to color steel plate work.)*
**Ductwork Standards**
1. **Duct Assembly**: Ducts must be glued before installation, with screws used at joints. Four corners must be tightened, and sealing strips added. Clips must be spaced 10 cm apart. After lifting, the air outlet must be taped.
2. **Hanging Code Spacing**: For ducts over 1500 mm, spacing is 2 meters; for those under 1500 mm, it's 2–3 meters.
3. **Insulation Cotton**: After hoisting, no leaks or damage should occur.
4. **Air Supply Opening**: The diameter must match the duct. Special cases require prior consultation with management and glass sealing.
5. **Valve Installation**: Must follow drawings. If unclear, coordinate with management.
6. **Reinforcement**: Ducts larger than 1500x500 mm need reinforcement.
7. **Equipment Room Ducts**: Reinforcement must be approved by management before installation.
8. **Leak Prevention**: No air or light leakage at hose interfaces.
9. **Space Constraints**: If site conditions don’t allow full compliance, consult management before proceeding.
