Below is a normalized interpretation of the technical framework in your source article, presented in a style more familiar to EU and North American readers.
Wear resistance and durability
Premium-category reference
- Lisport wear resistance: ≥11,000 cycles
- Fiber pull-out force: ≥3.8 N/mm
- Single-fiber breaking strength: ≥35 N
- Wear-performance decay after 10,000 load cycles: ≤8%
Vivaturf athletics warm-up configuration
- Lisport wear resistance: ≥16,000 cycles
- Fiber pull-out force: ≥4.8 N/mm
- Single-fiber breaking strength: ≥44 N
- Wear-performance decay after 10,000 load cycles: ≤4%
These values indicate a surface designed to withstand prolonged repetitive use with lower long-term degradation.
Comfort and safety-related movement response
Premium-category reference
- Vertical rebound ratio: 35%–42%
- Dry friction coefficient: 0.75–0.87
- Wet friction coefficient: ≥0.63
Vivaturf athletics warm-up configuration
- Vertical rebound ratio: 38%–41%
- Dry friction coefficient: 0.80–0.83
- Wet friction coefficient: ≥0.71
This supports a moderate rebound profile that feels comfortable and supportive without becoming overly rigid or unstable.
Weather resistance and dimensional stability
Premium-category reference
- UV aging strength retention after 5,000 h: ≥89%
- Performance retention at −25°C to +70°C: ≥87%
- Flatness tolerance: ≤3 mm/m
Vivaturf athletics warm-up configuration
- UV aging strength retention after 5,000 h: ≥95%
- Performance retention at −25°C to +70°C: ≥94%
- Flatness tolerance: ≤2 mm/m
These values suggest good durability in outdoor conditions and more stable full-field usability over time.
Environmental safety
Premium-category reference
- Heavy metal content: ≤100 mg/kg
Vivaturf athletics warm-up configuration
- Heavy metal content: ≤80 mg/kg
This supports use in school, public, and professional training environments where low-emission and safer-contact materials are increasingly important.
