The equipment must meet several specific requirements to ensure accurate and reliable results:

1. The falling weight should weigh 20kg, with an allowable error of ±0.5kg.
2. The spring must have an elongation range between 30 and 40N/cm.
3. The bottom diameter of the test platform should be 70mm.
4. The distance from the brace to the support center must be at least 200mm.
5. The distance from the bottom of the weight to the top of the spring must be adjustable with an accuracy of less than 1mm.
6. An electric lifting device must be used, equipped with an amplifier that provides at least 0.01mm precision.
7. Power deformation sensors are mounted on both sides, also with amplifiers, ensuring an accuracy of 0.01mm.
8. The recording device must be capable of storing data from both sensors, processing it, or displaying real-time readings—approximately 50 readings per test shot.

The testing process involves dropping a 20kg weight onto a spring, which then transfers the force to the lower test platform. The platform is equipped with sensors that record the increase in force during the impact. Additionally, deformation sensors installed on either side of the platform measure the surface's response to the load, providing detailed insight into its vertical deformation characteristics.

The vertical deformation value typically ranges between 0.6 and 1.8mm when tested at temperatures between 10°C and 40°C. This range ensures that the surface performs consistently across a wide variety of environmental conditions, making it suitable for use in professional sports facilities.
