Below are the test-referenced averages and ranges provided in your draft, expressed in common EU/NA technical language. These values should be verified with project-specific third-party testing as part of procurement and acceptance.
3.1 Weathering and outdoor durability (community-critical)
Service temperature range
- Vivaturf reference: −30°C to +80°C
UV aging
- 1,500 h UV exposure: colour fastness ≥ Grade 7
- Colour difference: ΔE ≤ 2
- Performance retention note: ≤ 5% degradation over the referenced period (installation and method dependent)
Fungal resistance
- ASTM G21: Class 0 (no growth observed under the referenced method)
Wind abrasion / stability indicator
- Referenced: stable under ≤ 15 m/s wind with no significant fiber collapse or loss (site conditions and installation dependent)
Why this matters: community pitches need consistent appearance and play feel across seasons without constant intervention.
3.2 Safety: impact protection + support (for mixed-age users)
Shock absorption / Force Reduction (FR)
- Referenced FIFA futsal guidance: 50%–65%
- Referenced community facility guidance: 45%–70%
- Suggested “best-fit” community range in your text: 52%–62%
- Vivaturf reference: 54%–60%
- Reported stability note: variation ≤ 3%
Vertical deformation
- Referenced FIFA futsal: 2.0–4.0 mm
- Community fit range in your text: 2.3–3.7 mm
- Vivaturf reference: 2.4–3.5 mm
- Recovery note: return to form after heavy use ≤ 20 minutes (field-use indicator; method dependent)
Why it matters: FR helps reduce impact loads (especially for youth/seniors), while deformation controls “support feel” so adults can still accelerate and stop confidently.
3.3 Traction and abrasion risk: slip control without over-grip
Sliding resistance
- Referenced FIFA futsal window: 0.38–0.66
- Vivaturf reference: 0.41–0.54
- Skin-friction reduction vs. infilled systems cited: > 28% (comparative intent; strongly method- and condition-dependent)
Why it matters: community surfaces must stay safe even when dust, light debris, or surface moisture is present—without becoming overly abrasive.
3.4 Mechanical durability: resisting wear, seam failure, and damage
Yarn and tuft structure
- Linear density (dtex): 12,000–13,000
- Tuft density: 17,000–18,000 tufts/m²
- Single-yarn tensile breaking force: ≥ 135 N
- Elongation at break: 40%–55%
- Tear resistance: ≥ 28 N/mm
Wear testing (Lisport XL)
- ≤ 4% fiber breakage after 20,000 cycles
Backing + seam integrity
- Backing bonding strength: ≥ 2.3 MPa
- Seam strength: ≥ 1,700 N / 50 mm
Why it matters: community pitches experience concentrated wear (goal mouths, center spots) and occasional misuse; seam and backing strength often determine real service life.
3.5 Drainage: keeping the pitch usable after rain
Your draft references:
- Drainage hole density: ≥ 25 holes/m²
- Water permeability rate: ≥ 10 L/(m²·min)
- After heavy rain: surface usable within ~20 minutes, with no persistent localized ponding reported (site drainage design dependent)
Why it matters: many community pitches have simplified drainage infrastructure; surface + backing drainage becomes a practical “uptime” factor.
3.6 Cleanability, weed suppression, and emissions (public-space readiness)
Soiling / stain adhesion rate
- ≤ 6% (cleaning-effort indicator in your text)
Weed growth rate
- ≤ 3% (suppression indicator; site conditions dependent)
Indoor/outdoor material safety indicators
- TVOC emission rate: ≤ 0.22 mg/(m²·h)
- Formaldehyde: not detected
- Heavy metal migration: ≤ 0.3 mg/kg
Why it matters: community operators need surfaces that remain “presentable” with basic cleaning routines and align with environmental expectations in residential settings.
