EN 1517-2020 pdf download.Surfaces for sports areas – Determination of resistance to impact.
This EN 1517 specifies a method for the determination of resistance to impact of sports floor systems.
It is primarily designed to be used on surfaces intended for use in indoor sports halls. The test can he undertaken in the laboratory or on site.
When undertaking tests on site, it is important to note that permanent damage to the sports floor can be caused.

cracking
vertical damage in the coating or top layer a minimum of 300 jim deep or any tearing or splitting damage to the underlying layers in the sports floor system
4 Principle
A weighted indenter is dropped from a given height onto the surface and the area of impact is subsequently examined for damage.
5 Apparatus
5.1 A cylindrical indenter as shown in Figure 1 and having a diameter (11.3 ± 0,3) mm, with a flat contact surface having an edge radius of diameter (1,25 ± 0,1) mm, a mass of (800 ± 10) g and means of dropping the indenter vertically down a guide tube from a height of (1 ± 0,01) m, essentially without friction.
5.2 Pocket-lens/microscope with a magnification of x 4.
5.3 Laboratory thermometer capable of recording the surface temperature of the test specimen to 0,5 °C.EN 1517-2020 pdf download.
