- Phthalates (DEHP/DBP): <0.05% (CPSC & Canada CPSA compliant).
- Lead/Cadmium Content: <20 ppm (CPSC 16 CFR Part 1303 compliant).
2.8 Packaging & Labeling
- Carton Drop Test: Passed ISTA 3A (1.5m drop, no damage).
- Label Compliance:
- U.S.: “CARB Phase II Certified,” “Patent License: Unilin/Valinge [Insert].”
- Canada: Bilingual (English/French) – “Fire Class A,” “Slip Resistance R10.”
- Flooring Class (AC5), installation guidelines included.
3. Non-Conformities (5% of Batch)
- Minor Defects:
- 8/200 planks exhibited slight embossing-texture mismatch.
- 5/200 cartons lacked bilingual fire rating labels.
- Resolution:
- Defective planks replaced; labels reprinted and re-verified.
4. Conclusion
The SPC flooring achieved a 95% pass rate, meeting all critical requirements for patent compliance, structural strength, surface durability, waterproof/fireproof performance, slip resistance, and environmental regulations. Approved for shipment to the U.S. and Canadian markets.
