Floor compliance refers to the ability of a floor to absorb and dissipate energy, which is crucial for reducing the impact on the body during activities like walking, running, or jumping. This is particularly important in sports facilities, dance studios, and other environments where high-impact activities are common. Here are some key points to consider when evaluating floor compliance:

1. Force Reduction

• Definition: The percentage of impact energy absorbed by the floor.


• Importance: Higher force reduction means less stress on joints and muscles, reducing the risk of injuries.


• Measurement: Typically measured using specialized equipment that drops a weight onto the floor and measures the rebound.

2. Standard Deformation

• Definition: The amount of vertical deformation (compression) of the floor under a standard load.


• Importance: Indicates how much the floor will compress under impact, which can affect performance and safety.


• Measurement: Usually measured in millimeters and can be tested using a standardized load.

3. Energy Restitution

• Definition: The percentage of energy returned to the user by the floor.


• Importance: Affects the rebound effect, which can influence performance in activities like jumping.


• Measurement: Often measured in conjunction with force reduction.

4. Rolling Load

• Definition: The ability of the floor to withstand rolling loads, such as those from wheelchairs or equipment.


• Importance: Ensures the floor can handle various types of traffic and equipment without damage.


• Measurement: Tested by rolling a standardized load across the floor and measuring deformation.

5. Shock Absorption

• Definition: The floor's ability to absorb shock from impacts.


• Importance: Reduces the risk of injuries and improves comfort during high-impact activities.


• Measurement: Can be measured using impact testing equipment.

6. Vertical Deformation

• Definition: The amount the floor compresses under a vertical load.


• Importance: Affects the feel and performance of the floor, especially in sports and dance.


• Measurement: Measured in millimeters using a standardized vertical load.

7. Ball Rebound

• Definition: The height to which a ball rebounds after being dropped from a standard height.


• Importance: Particularly relevant for sports like basketball, where ball behavior is crucial.


• Measurement: Measured by dropping a ball from a standard height and recording the rebound height.

8. Friction

• Definition: The resistance to sliding or slipping on the floor.


• Importance: Affects safety and performance, especially in activities requiring quick changes of direction.


• Measurement: Measured using friction testing equipment.

9. Durability

• Definition: The floor's ability to maintain its properties over time and with repeated use.


• Importance: Ensures long-term performance and safety.


• Measurement: Assessed through long-term use and periodic testing.

10. Comfort

• Definition: The overall feel and comfort of the floor for users.


• Importance: Affects user satisfaction and can influence performance and safety.


• Measurement: Often subjective but can be assessed through user feedback and surveys.

Standards and Certifications

• ASTM F2772: Standard specification for athletic performance properties of indoor sports floor systems.


• EN 14904: European standard for sports floors.


• DIN 18032-2: German standard for sports floors.

Conclusion

Floor compliance is a multifaceted concept that involves various performance metrics. Ensuring that a floor meets the necessary standards for compliance can significantly enhance safety, performance, and user satisfaction. It is essential to consider the specific needs of the activity and environment when selecting a compliant flooring solution.
