ENGINEERED HARDWOOD FLOORING QUALITY INSPECTION REPORT
1. Raw Materials & Certifications
| Material | Description | Required Certifications |
|---|
| Top Veneer (Wear Layer) | Solid hardwood (Oak, Maple, Walnut, etc.) | FSC, PEFC, CE, CARB Phase 2 |
| Core Layer (Plywood/HDF) | Multi-layer birch plywood or HDF | E1/E0 (Low formaldehyde), EPA TSCA Title VI |
| Backing Layer | Balancing layer (softwood or polymer) | ISO 14001 (Environmental Mgmt.) |
| Adhesives | Low-VOC, formaldehyde-free glue | GREENGUARD Gold, UL ECOLOGO |
| Finish (UV/Oil/Polyurethane) | Protective coating for durability | ASTM D2859 (Flammability), EN 13329 |
2. Common Defects & Inspection Criteria
| Defect Type | Description | Acceptance Standard |
|---|
| Surface Cracks | Micro-cracks in the top layer | ≤ 0.1mm depth, ≤ 5mm length |
| Warping/Cupping | Uneven board edges due to moisture | ≤ 1mm deviation over 1m length |
| Color Inconsistency | Mismatch between batches | ΔE ≤ 2.0 (CIELAB standard) |
| Groove/Tongue Damage | Chipped or misaligned locking system | Must fit tightly (gap ≤ 0.2mm) |
| Finish Bubbles/Scratches | Imperfections in coating | No visible defects at 1m distance |
3. Performance & Laboratory Test Data
| Test Item | Standard | Requirement | Test Result |
|---|
| Moisture Resistance | EN 13329 | Swelling ≤ 12% | 8.5% (Pass) |
| Abrasion Resistance | ASTM D4060 (Taber Test) | ≥ 5000 cycles | 6500 cycles |
| Impact Resistance | EN 14354 | No cracks | Pass |
| Formaldehyde Emission | CARB Phase 2 / EN 717-1 | ≤ 0.05 ppm | 0.03 ppm |
| Dimensional Stability | EN 434 | ≤ 0.15mm/m | 0.10mm/m |
| Slip Resistance | DIN 51130 | R9-R10 | R9 (Pass) |
| Fire Resistance | ASTM E84 | Class A | Class A |
4. Manufacturing Process Overview
| Production Step | Key Details |
|---|
| 1. Veneer Slicing | Top layer sliced (0.5mm–6mm) from solid hardwood logs. |
| 2. Core Layer Prep | Plywood/HDF pressed under high heat and pressure. |
| 3. Gluing & Layering | Adhesive applied (PUR or EVA), then pressed (cold/hot). |
| 4. Finishing | UV/Oil/Polyurethane coating for durability. |
| 5. Milling & Profiling | Tongue-and-groove edges cut for installation. |
| 6. Quality Inspection | Visual checks, lab tests, and moisture content verification. |
| 7. Packaging | Sealed in moisture-resistant wrapping. |
Notes:
- Certifications Needed: FSC (sustainable sourcing), CARB Phase 2 (low formaldehyde), GREENGUARD Gold (indoor air quality).
- Critical Tests: Moisture resistance, abrasion, and formaldehyde emissions are key for compliance.
- Defect Tolerance: Minor defects allowed per EN 14342 (European standard) or NWFA (US).
