4. Detailed Inspection Items & Test Results
4.1 Dimensional Tolerance Inspection (Compliant with ANSI/HPVA EF 2020)
All dimensional indicators are tested by professional precision measuring tools, and all results are within the allowable tolerance range of US national standards:
- Length Deviation: ≤ ±0.3mm (Standard Requirement: ≤ ±0.5mm) – Pass
- Width Deviation: ≤ ±0.2mm (Standard Requirement: ≤ ±0.3mm) – Pass
- Thickness Deviation: ≤ ±0.2mm (Standard Requirement: ≤ ±0.4mm) – Pass
- Straightness & Flatness: No warping, bending or edge skew; surface flatness fully meets US on-site installation requirements – Pass
- Lock Joint Gap: Click-lock splicing gap ≤ 0.1mm, tight and seamless assembly – Pass
4.2 Substrate & Structural Quality (Plywood Core, ANSI/HPVA HP-1)
Focus on verifying the structural stability and internal quality of the plywood core, the core substrate of the product:
- Core Material Consistency: Full plywood core, no HDF/MDF mixed filling, uniform layer thickness, neat lamination – Pass
- Internal Defect Detection: No hollow core, delamination, crack, insect hole or decay inside the plywood core – Pass
- Adhesive Bonding Strength: Layer bonding strength ≥ 500N, no degumming or layering after tensile test, meeting US flooring load-bearing and anti-separation standards – Pass
- Structural Stability: Cross-laminated structure effectively offsets wood internal stress, adapts to the humidity and temperature climate of Houston, USA, and avoids seasonal deformation –Pass
4.3 Appearance Quality Inspection (NOFMA Standard)
Inspect surface veneer, finish and overall appearance of flooring planks to meet US commercial-grade flooring appearance requirements:
- Surface Veneer: Natural hardwood veneer with clear texture, uniform color, no obvious color difference, scratch, dent, crack or spot – Pass
- Surface Finish: Uniform UV coating, smooth surface, no bubbling, peeling, orange peel or foreign matter adhesion – Pass
- Edge & End Face: Neat cutting, no burr, collapse edge or crack; professional waterproof sealing treatment on all edges – Pass
- Overall Grade: Meet NOFMA First Grade commercial flooring standard, suitable for residential and light commercial scenarios in the United States
4.4 Physical & Mechanical Performance Test
- Wear Resistance: UV finish wear resistance meets ANSI/HPVA EF 2020 standard, resistant to daily friction and household wear – Pass
- Impact Resistance: No surface depression or coating peeling after standard impact test, good toughness – Pass
- Water Resistance: After 24-hour constant temperature humidity test, no edge expansion, delamination or surface blistering, adapting to Houston’s humid subtropical climate –Pass
- Locking System Strength: Click-lock interlocking structure bears dynamic load stably, no loose connection or dislocation after repeated assembly and disassembly – Pass
4.5 Environmental Protection & Emission Compliance (TSCA Title VI & CARB P2)
As mandatory US import compliance items, formaldehyde and VOC emissions are fully tested to meet federal and California regional strict standards:
- Formaldehyde Emission: Test result ≤ 0.05ppm, far lower than TSCA Title VI and CARB Phase 2 mandatory limit (≤ 0.08ppm) – Pass & Compliant
- VOC Emission: Meet FloorScore and GREENGUARD Gold low emission standards, no harmful volatile substances, compliant with US indoor air quality requirements – Pass
- Adhesive Environmental Performance: All adhesives used for plywood lamination are low-formaldehyde environmental protection glue, compliant with US composite wood product environmental access rules – Pass
4.6 Packaging & Shipping Compliance
- Outer Packaging: Standard export carton with waterproof and shockproof protection, firm packaging, no damage or deformation – Pass
- Labeling: Clear product specification, origin mark (Made in Vietnam), batch number, safety certification mark and US standard compliance label – Pass
- Shipping Adaptability: Packaging adapts to long-distance ocean transportation to Houston, moisture-proof and pressure-resistant, avoiding cargo damage during transit –Pass
5. Non-Conformity Description
After full inspection of the sampled batch of products,no quality non-conformity items, no safety hazards and no standard non-compliance issues are found. All inspection indicators fully meet the requirements of US engineered hardwood flooring official standards.
6. Comprehensive Inspection Conclusion
The inspected batch of Vietnamese-made engineered hardwood flooring with plywood core has passed full dimensional, structural, appearance, mechanical performance and environmental emission tests. All indicators strictly comply with ANSI/HPVA EF 2020, ANSI/HPVA HP-1, TSCA Title VI, CARB Phase 2 and NOFMA US industry standards.
