Strength, functionability and safety are brought into focus for the new European classification of ceilings (EN 13964, Annex D) in sports halls, gyms and other leisure areas. To meet the highest demand of the new standard, Class 1a ceiling systems need to be able to withstand a ball impact equal to speed of 60km/h. without being adversely affected. At the same time, the ceiling or wall panels should be Class A sound absorbers to limit noise levels. Indeed with tinnitus recognized as a growing problem amongst sports teachers, it is even more vital to install adequate sound absorbing materials.

The Ecophon Super G range of acoustic ceiling systems offers a solution for all these requirements, providing the impact resistance defined in the new standard as well as Class A sound absorption according to EN ISO 11654. The ceilings and wall panels are available in white or light grey strong glass fibre fabric and can be installed in a variety of ways to meet different classes of impact resistance.

The test method used for ceilings can also be applied on wall panels (according to the German standard DIN 18032). Ecophon’s wall panel systems, with Class A sound absorption, also meet the same criteria as the ceiling systems when tested for impact resistance.

NOTE: European Standard, EN 13964, Annex D describes three levels of classification, 1a, 2a, 3a, for ceiling systems. In the test a handball with the approximate weight of 0.45 kg (1 lb) is fired towards the ceiling with a special ball gun apparatus. The test specimen should be hit 36 times from three different angles. The hits should be uniformly distributed over the surface, i.e. tiles, profiles and intersection between profiles will be subjected to hits during the tests.

If a weak spot appears during the test the executer of the test should try to hit this spot with further shots.

Classes Impact Velocity

1a 16.5 +/- 0.8

2a 8.0 +/- 0.5

3a 4.0 +/- 0.5

The classification achieved depends on the choice of impact velocity of the ball. 16.5 m/s is equal to a speed of approximately 60 km/h.
