| Surface Roughness | Uneven sanding or machining marks | Smooth, no visible tool marks |
| Glue Residue | Excess adhesive on edges/surface | No visible residue |
| Color Variation | Inconsistent staining/finishing | Within approved sample range |
4. Laboratory Test Data (Performance & Functional Tests)
| Test Item | Standard | Requirement | Test Result |
|---|
| Moisture Content (%) | ASTM D4442 | 8%-12% | 10.2% |

| Paint Adhesion | ASTM D3359 | Class 4B (Cross-Cut) | Pass |
| Abrasion Resistance | EN 438-2 | ≤0.08g/100 cycles | 0.06g |
5. Production Processes & Joinery Methods
| Process | Description | Quality Control Check |
|---|
| Kiln Drying | Reduces moisture to 8-12% | Moisture meter verification |
| Planer Milling | Shapes profiles (e.g., baseboard, crown) | CNC precision (±0.5mm tolerance) |
| Finger Jointing | End-to-end splicing for long lengths | Glue line strength ≥ wood strength |
| Sanding | 120-220 grit for smoothness | Visual & touch inspection |
| Finishing | Staining/varnishing (spray/dip) | Even coating, no drips/bubbles |
Common Joinery Methods:
- Butt Joint (Simple end-to-end, glued/nailed)
- Miter Joint (45° angle cuts for corners)
- Spline Joint (Reinforced with a wooden strip)
- Tongue & Groove (Interlocking edges for stability)
Notes:
- All test results should comply with international standards (e.g., ANSI, EN, ISO).
- Rejected batches must be reworked or discarded based on defect severity.
