2. Common Processing Defects in T&G Plywood
| Defect Type | Description | Acceptance Criteria | Remarks |
|---|
| Misaligned Tongue & Groove | Improper fitting due to machining error | Must fit snugly without gaps | Rejected if gap > 0.5mm |
| Chipped Edges | Splintering during slotting | No visible splinters > 2mm | Sanding required if minor |
| Glue Residue | Excess adhesive on surface/groove | No sticky residue | Clean before approval |
| Warping/Twisting | Panel deformation after machining | Max 3mm bow over 1m length | Rejected if exceeding |
| Surface Scratches | Damage from handling/machining | Light scratches allowed, no deep marks | Cosmetic issue |

| Density | 550 – 700 kg/m³ | [e.g., 620 kg/m³] | Pass |
| T&G Joint Strength | No failure under 500N load | Passed | Pass |
4. Plastic Tongue Quality Standards & Common Defects
| Inspection Criteria | Requirement | Common Defects | Remarks |
|---|
| Material | High-density PVC/Nylon | Brittleness, cracks | Reject if cracked |
| Dimensional Accuracy | ±0.2mm tolerance in width/depth | Loose fit, oversized | Must match groove |
| Color Consistency | Uniform, no discoloration | Streaks, uneven dye | Cosmetic issue |
| Flexibility Test | No breakage when bent 90° | Cracking upon flex | Rejected if fails |
| Adhesion to Plywood | No separation under 50N pull force | Weak bonding | Rejected if glue fails |
5. Conclusion
✅ Overall Result: Pass / Fail (Delete as applicable)
📝 Remarks:
- Minor defects (if any): [Specify, e.g., “Minor surface scratches, acceptable after sanding”]
- Major defects (if any): [Specify, e.g., “Warping exceeds tolerance – batch rejected”]
