1. Raw Materials and Quality Specifications

Wooden computer desks are manufactured using a combination of natural and engineered materials to ensure durability, functionality, and compliance with Dubai’s import regulations.

A. Wood Components

• Solid Wood:
• Types: Pine, rubberwood, or oak for structural frames and legs.
• Quality Requirements:
  • Moisture Content: 8–10% (measured with pin-type moisture meters).
  • Defect Limits: No cracks, insect holes, or knots exceeding 3 mm in diameter.
• Engineered Wood:
• Types: Medium-density fiberboard (MDF) or plywood for tabletops and shelves.
• Quality Requirements:
  • Density: MDF ≥ 720 kg/m³ (EN 622-1 standard).
  • Formaldehyde Emissions: ≤0.05 ppm (CARB Phase 2 or EN 717-1 compliant).

B. Surface Coatings and Finishes

• Common Treatments:
• UV-Cured Coatings: 2–3 layers for scratch and heat resistance.
• Veneers: Oak or walnut veneers (0.5–1.2 mm thickness) bonded with E0-grade adhesives.
• Laminates: High-pressure melamine surfaces for moisture resistance.
• Quality Requirements:
• Adhesion Strength: ≥3.0 MPa (ASTM D3359 cross-cut test).
• Heat Resistance: No blistering after 24 hours at 60°C (ISO 4211).

C. Metal Hardware

• Types: Powder-coated steel brackets, aluminum drawer slides, and zinc-alloy screws.
• Quality Requirements:
• Load Capacity: Desk legs withstand ≥100 kg static load (EN 16121).
• Corrosion Resistance: Pass 72-hour salt spray test (ASTM B117).

2. Production Process and Critical Control Points

A. Material Preparation

1. Wood Conditioning: Kiln-dried to 8–10% moisture content; stored in humidity-controlled environments.
2. Panel Cutting: CNC machines cut tabletops and shelves with ±0.3 mm dimensional accuracy.

B. Assembly Process

1. Frame Construction: Dowel and cam-lock joints for modular assembly.
2. Adhesive Bonding: PVA or polyurethane adhesives applied uniformly; excess glue removed to prevent surface stains.
3. Hardware Installation: Drawer slides and cable management slots aligned using laser-guided tools.

C. Surface Finishing

1. Sanding: Automated belt sanders (180–240 grit) achieve smooth, splinter-free surfaces.
2. Coating Application: Spray guns apply primer and topcoat; UV curing ensures rapid hardening.
3. Edge Banding: PVC or ABS edging applied to prevent chipping and moisture ingress.

3. Quality Inspection Standards and Methods

A. Structural and Functional Tests

• Stability Test: Desk subjected to 50 kg lateral force; maximum tilt angle ≤1.5° (BS EN 14749).
• Drawer Slide Test: 15,000 open-close cycles; no jamming or misalignment.
• Surface Load Test: 25 kg weight placed on tabletop for 24 hours; deflection ≤2 mm.

B. Aesthetic Inspection

• Visual Inspection: Examined under 600-lux LED light for scratches, color mismatch, or coating bubbles.
• Edge Smoothness: Rounded edges (radius ≥1.5 mm) to meet Dubai’s safety standards.

C. Safety and Compliance

• Formaldehyde Testing: Per ISO 12460-3; emissions ≤0.05 ppm.
• Fire Resistance: Surface materials meet Class B fire rating (BS 476-6).

---

4. Common Defects and Acceptance Criteria

A. Aesthetic Defects

• Minor Issues: Slight grain variation or minor coating unevenness (≤5% of units per batch).
• Rejectable Defects: Cracks, exposed edges, or visible glue residues (≤1.2% rejection rate).

B. Functional Defects

• Structural Weakness: Joint separation under load testing (≤0.5% rejection).
• Hardware Failure: Loose screws or stuck drawers (≤1% tolerance).

C. Overall Yield: 97.5% of production meets export standards after re-inspection.

5. Packaging and Containerization Guidelines

A. Packaging Specifications

• Inner Packaging:
• Anti-scratch foam sleeves and corner guards for tabletops.
• Silica gel desiccants (8g/m³) to mitigate humidity during transit.
• Outer Cartons: Triple-wall corrugated boxes with reinforced edges; labeled with handling symbols (e.g., “This Side Up”).
• Documentation: Includes assembly manuals, FSC certification, and compliance stickers.

B. Container Loading Protocol

1. Pallet Configuration: Euro pallets (1200×800 mm) stacked ≤1.2 m high; weight ≤1,000 kg per pallet.
2. Weight Distribution: Max 20 tons per 40HQ container to avoid floor damage.
3. Securement: Nylon straps and edge protectors to prevent shifting; anti-slip mats between layers.
4. Climate Control: Use ventilated containers; avoid exposure to direct sunlight during storage.

C. Critical Precautions

• Pest Control: Wood materials must comply with ISPM 15 (heat-treated with stamped mark).
• Customs Compliance: Include UAE Conformity Assessment (ECAS) certificates.
• Pre-Shipment Audit: Third-party inspection (e.g., TÜV or Bureau Veritas) for 10% of randomly selected units.
