Six main technical indicators of sports wood flooring According to the three characteristics that sports wood flooring should have, namely sports functionality, protective functionality and technical performance, the International Sports Floor Technical Committee quantified the technical indicators and adopted the six main technical indicators of sports wood flooring stipulated in the second chapter of the German DINl832 standard. In other words, the wooden floor can only be called sports wooden floor if it has the above three characteristics and meets the following six main technical indicators.

♂? Motor function

The floor should have good impact absorption performance, minimize the rebound force and try to avoid the athletes' bones being shaken by the rebound force.

defencive function

The ground should have a certain "toughness", but it should not be as hard as cement ground, and the vertical deformation height of the ground should not be less than 2.3 mm

engineering data

The floor should be "rigid", the rebound height of the ball should be ≥90%, and the friction coefficient of the floor surface should be moderate. The athlete's footsteps suddenly stop during the movement until the footsteps finally stop. During this period, the sliding distance should be kept between 0.4 and 0.6 m, and the minimum rolling load should be 2500N·N N. ..
