Vivaturf 7-a-side systems are engineered to align with FIFA-referenced performance ranges and national testing frameworks such as GB/T 36057-2018, while reflecting real-world operational conditions.
2.1 Player-Surface Interaction Parameters
- Shock absorption: 56%–63% (within recommended operational range approx. 55%–65%)
- Vertical deformation: 2.3–3.6 mm
- Ball rebound ratio: 0.73–0.87
- Rolling friction coefficient: 0.43–0.56
- Sliding resistance: 0.42–0.53
These ranges aim to provide controlled impact attenuation while maintaining efficient force transfer during acceleration and directional movement.
2.2 Durability and Structural Stability
7-a-side facilities typically experience concentrated wear. Structural performance indicators include:
- Lisport XL mechanical wear test:
- Fiber breakage ≤3% after 10,000 cycles
- Fiber tensile performance:
- Breaking force ≥140 N
- Elongation at break 42%–56%
- Tear resistance ≥29 N/mm
- Backing bonding strength ≥2.4 MPa
- Seam strength ≥1700 N / 50 mm
- UV aging (1000 h): colour fastness ≥Grade 7
- Climate tolerance range: −30°C to +78°C
- Mold resistance: ASTM G21 rating 0
2.3 Drainage and Environmental Stability
- Permeability ≥9.5 L/(m²·min)
- Multi-layer drainage integration (surface → backing → base system)
- Rapid surface recovery after rainfall under typical drainage design conditions
2.4 Environmental and Operational Indicators
- Heavy metal migration ≤0.3 mg/kg
- TVOC emission rate ≤0.23 mg/(m²·h)
- Formaldehyde not detected in referenced testing
- VOC emissions during manufacturing ≤4.5 mg/m³
Modular installation systems support flexible pitch layouts and efficient renovation cycles, with typical installation timeframes reduced by approximately 25%–30% compared with infilled construction methods.
