​​What is a Surface Impact Test?

Our Surface Impact Test evaluates the shock-absorbing properties of playground surfacing materials. It determines whether the surface meets the Critical Fall Height (CFH) requirements for your playground equipment as per NZS 5828:2015 and EN1177 standards.

 

Using our HIC Surface Impact Tester, we simulate real-world fall scenarios and assess the surface's ability to absorb impact and reduce the risk of serious injury.

​​

What's Included in the Test?

• Impact Drop Testing using a calibrated Head Injury Criteria (HIC) device

• Measurement of fall height per activity to determine relevant test points

• Multiple drops performed from increasing heights to determine Critical Fall Height (CFH)

• Impact severity measured for each drop (Head Injury Criteria - HIC and Gmax values)

• Drop Curve Graph generated to visually represent impact vs. height

• Digital Test Report including:

  • Pass/Fail outcome based on compliance

  • Site photos and documentation

  • Summary of surface condition and maintenance notes

​​

How the Test Works

Our testing process uses a sensor-equipped headform to replicate a fall and measure key impact metrics such as:

• Velocity at impact

• Gmax (maximum deceleration)

• HIC (Head Injury Criteria)

 

From this data, we determine whether your surface can sufficiently absorb energy from a fall and prevent traumatic injury. This ensures your surfacing aligns with the CFH requirements of nearby play equipment.

Common Surface Types We Test

We test a wide range of surfacing systems, including:

• Play Matta® Tiles

• Numat Tiles

• Wetpour Rubber

• Synthetic Turf with or without infill

• Grass Retenion Tilles

• Pour’n’Play systems

• Corkeen/Mulch Set Products

• Any other custom surface installations

​​

Why Regular Testing Matters

All playground surfaces degrade over time due to UV exposure, heavy usage, and weather. Regular testing helps you:

• Identify safety risks before they lead to injury

• Maintain compliance with NZS5828 + EN1177 standards

• Avoid costly liabilities or required surface replacement

• Provide peace of mind to caregivers, operators, and councils

​​

Test Options

• On-site (in-situ) Testing: For existing playgrounds and surface installations

• Lab-Based Certification: For new surface systems or product testing at our facility (Contact us for more details)
