Bottom line: Lock quantitative criteria before production. Catch defects on the Foshan factory floor. Ideal for: Project managers and procurement teams.
1. Inspection Baseline
- CAD: Approved millimeter shop drawings.
- Samples: Signed physical master samples.
- Tolerances: Contractual numerical limits.
2. Dimensional Tolerances
- Cabinetry: ±1.0 mm (width, depth, height).
- Windows: ±1.5 mm (frame), ±1.0 mm (diagonal).
- Tiles: ±0.5 mm (size and thickness).
- Glass: ±1.0 mm (size), ±0.5 mm (hole centers).
3. Surface Finish
- Lacquer: 80–120 microns, zero overspray.
- Aluminum: Powder coat ≥60 microns.
- Tiles: Dry-lay grading for tonal consistency.
- Plumbing: PVD scratch and corrosion resistance.
4. Functional Testing
- Drawers: Cycle test soft-close slides.
- Doors/Windows: Verify sliding friction and locks.
- Tapware: Pneumatic testing (0.6 MPa).
- Lighting: Burn-in and CCT checks where specified for the project.
5. Hardware Completeness
- Audits: Match screws and brackets to BOM.
- Spares: Include 3–5% spare hardware.
- Keys: Verify master keying hierarchy.
6. Packaging & Loading
- Crates: Fumigated wood with corner guards.
- Labels: Room-by-room barcodes.
- Supervision: Load heavy cargo on floor, verify seals.
Defect Protocol
- Minor: Touch up before loading.
- Major: Agree the rework plan and timing with the project team before loading.
- Critical: Reject and trigger remake.
