The adjusted sample level is placed on the test position of the rebound tester, and the height of the bottom of the steel ball from the fixed position to the surface of the foam plastic is reduced to 460mm by adjusting the height of the steel ball. The steel ball is fixed on the release device, and then the ball is free to fall. Make a three rebound for each specimen and take the maximum value of the three rebound. Each rebound ball shall fall at the same location on the surface of the sample, and the time interval of the two rebound shall be controlled within 20s. If the ball meets or pops the measuring device during the rebound, the data is invalid and needs to be re - filled.
