How do we choose SPC flooring for daily decoration

The core quality standards for spc flooring include physical performance indicators, environmental certification parameters, substrate stability testing, and appearance process requirements of the national standard GB/T 34440-2017. The following is a specific classification analysis:
1、 National standard requirements (GB/T 34440-2017)
Physical performance:
Tensile strength: not less than 15 MPa (tensile strength of the substrate layer)
Elongation at break: meets standard requirements (usually ≥ 15%)
Thickness deviation: not exceeding ± 0.1mm
Dimensional stability (underfloor heating test): shrinkage rate<0.5%
2、 Substrate and stability testing
Substrate density: tested by 30 degree diagonal bending without fracture, corresponding to a density>2000kg/m ³
Lock design: When installing SPC flooring, it is necessary to ensure tight and seamless splicing, and secure installation
Anti slip performance: friction coefficient meets the standard after wet water (commonly tested by olive oil penetration test)
3、 Environmental certification standards
Formaldehyde emission: SPC flooring needs to reach E0/E1 level (≤ 0.05mg/m ³ or ≤ 0.124mg/m ³)
TVOC release amount:<0.25mg/m ³ (medical grade standard)
Authoritative certification: CARB certification, FloorScore certificate (EC10076 standard)
4、 Appearance and process indicators
Surface requirements: flat and smooth, without color difference, bubbles or cracks
Wear resistant layer thickness: ≥ 0.3mm (high-quality products can reach 0.5mm or more)
Printing process: Clear and realistic texture, uniform color
5、 Testing method reference
Substrate testing:
Key scratch test (no debris)
Pour boiling water over the joint (no expansion for 5 minutes)
Thickness measurement: Error ≤ 0.08mm at left, center, and right (high-quality product)
Waterproof test: including salt soaking, olive oil penetration, and underfloor heating baking
Purchase suggestion: Prioritize choosing branded products that have complete environmental certifications (such as CARB, FloorScore), meet substrate density standards, and provide formal after-sales service.
The SPC flooring produced by Feixue New Materials Company fully meets all the above standards. Please feel free to inquire
