How do you assess sports flooring's anti-slip and impact absorption?
Anti-Slip, impact absorption, and ball rebound are the 3 core performance metrics of sports flooring, and they constrain one another. We explain the definition of each metric, the test methods, and the balance and trade-offs for different scenarios.
｜
PERFORMANCE BALANCE
Do not look at a single parameter alone; look at the balance of the three items
Higher is not always better for Anti-Slip, cushioning, and ball rebound. For scenarios such as campus basketball, kindergartens, public walkways, and go-karting, the core differences lie in the trade-offs among friction, impact absorption, and athletic feedback.
115 BPNDry pendulum friction, emphasizing anti-slip stability
R10Reference for anti-slip grades commonly used in public spaces
30–70%Impact absorption adjusted for sports or children's scenarios
≥95%Basketball courts focus more on ball rebound feedback
Choosing sports flooring shouldn't come down to just asking "is it soft?" or "is it slippery?" — first determine the user group, the sport, fall risk, and ball-feel requirements.

Three core performance attributes explained
1. Anti-Slip (Friction)
Measures the surface's ability to resist sliding. Two test methods:
- BPN Method (British Pendulum Number): Pendulum test, national standard minimum ≥ 47. AnchorCare Interstellar reaches BPN 115 (dry state).
- R-rating (DIN 51130): Inclination test under oily conditions, graded into five levels R9–R13. R10 is a common requirement for public venues.
2. Impact Absorption
Measures the surface's ability to cushion impact. Higher values are softer (suited for kindergartens / public walkways), lower values are firmer (suited for high-bounce basketball).
- Test Method: a manual impact hammer (25kg) dropped from a fixed height to measure the absorption percentage
- Typical range: Basketball court 25–35%, gym 35–55%, kindergarten 50–70%, high-fall zone 70–80%
3. Ball rebound rate
Measures the playing feel of basketball-type sports on a surface. A standard basketball dropped freely from 1.8 meters, expressed as the percentage of rebound height / original height.
- National Standard Baseline ≥ 90%
- Professional court ≥ 95%
- Competition-grade ≥ 98%

Balancing trade-offs across different scenarios
Basketball court (5v5 / 3x3)
- Main conflict: ball rebound vs impact absorption
- Solution: ball rebound ≥ 95% + 25–35% impact absorption (enough cushioning to protect the knees without reducing ball rebound)
- Recommended:ANK5 Jumbo / Quantum Stack
Kindergarten Activity Areas
- Main conflict: impact absorption vs anti-slip
- Solution: 50–70% impact absorption + R10 anti-slip
- Recommended:ANK4 Cloverleaf / SVS1
Public circulation / corridor / poolside
- Main conflict: anti-slip (switching between dry and wet conditions) vs walking comfort
- Solution: R10–R11 anti-slip + 30–50% impact absorption + flat surface that doesn't impede walking
- Recommended:Interstellar (Anti-Slip granular points + R10)
High fall zone (slide landing / beneath climbing frames)
- Main conflict: impact absorption (cushioning injury) vs long-term durability
- Solution: 70–80% impact absorption + increased thickness (25–35mm)
- Recommended:SVS1 POLAR STAR thick version
How to read a sports performance report
A qualified sports performance test report should clearly state:
- Test Standard: BPN (GB/T 22517) / R grade (DIN 51130) / impact absorption (GB/T 19851 / EN 14904) / ball rebound (EN 14904)
- Test Conditions: Temperature 23±2℃, humidity 50±5%
- Test Results: Value + whether it meets the standard
- Number of Test Points: ≥ 5 points averaged (to avoid single-point deviation)
When reading the report, note the following:The sports performance of the same product varies with thickness. For example, SVS1 Polaris 17mm vs 35mm differ greatly in impact absorption. When purchasing, be clear aboutActual purchased thicknessthe corresponding report.
When you are unsure which model meets your needs, you can refer to 14-product parameter details, or search by scenario Campus basketball court / Kindergarten dedicated recommendations.
FAQ
Is higher impact absorption always better?
No. If impact absorption is too high (> 60%), the surface becomes soft, ball rebound drops noticeably, and basketball-type sports feel very poor.For professional basketball courts, 25–35% impact absorption is the golden range。
Is a higher Anti-Slip coefficient always better?
No. If friction is too high (BPN > 130), feet will catch when turning or stopping abruptly (risk of ankle sprain).BPN 60–90 is the comfort zone for most sports, R10 is the general requirement for public venues.
What is the difference between R10 and R11 slip resistance ratings?
R10 is suitable for general public spaces (schools, shopping centers, office buildings); R11 is for areas prone to moisture (kitchens, wet rooms, poolside). R12 and above is for industrial environments (factory floors). Sports flooring rarely requires R12 or higher.
Which standard is stricter: BPN or R rating?
Test conditions differ, so there is no direct conversion relationship.BPN is commonly used in China and Commonwealth countries; R-rating is used in Europe. A qualified product should be tested against both standards. AnchorCare Interstellar passes both BPN 115 (dry) + grade R10.
What is the Anti-Slip granule anti-slip technology?
AnchorCare's proprietary micro-raised surface structure uniformly distributes 500,000 micro-granule points per m² across the flooring surface, providing physical anti-slip performance in both dry and wet conditions. +100% (dry) / +150% (wet) friction vs. standard PP flat surface.
