According to DIN 18032-3 “Halls for gymnastics, games and multi-purpose use, testing of safety against ball throwing” and DIN 57710-13 “Luminaires with operating voltages below 1000 V; luminaires safety for ball throwing”,
To pass this standard test, luminaires are tested by using a ball-shooting device. The fitting needs to withstand 36 handball shot from three different directions at an impact speed of 60 km/h. The fitting must work normally without any loose or broken parts falling down after the test. So the material of luminaires and accessories must be classified as ball-proof.
