According to the standard, the test for safety against ball throwing of ceiling elements consists of two categories, namely D1 and D2 (D=German abbreviation for ceiling). The test procedure is almost identical in both cases, only the impact speed is different. A handball is shot twelve times from three different angles at the relevant ceiling element, using a special ball shooting machine. The launch speed is precisely calculated in advance based on the distance between the ball shooting machine and the ceiling element (at least 1.50 m), so that the impact speed is always the same and complies with the standard.

An impact speed of 60 km/h is specified as a guideline for a category D1 ceiling element, and 85 km/h for category D2. Since products that function as ceiling elements must always be tested for safety against ball throwing before they are launched on the market, this test is carried out in a certified laboratory, where the elements are attached to a test ceiling in the same way they will be installed in the sports hall at a later date.

A ceiling element has been certified as safe against ball throwing if it does not show any serious damage after the ‘attack’ (and this includes even paint chipping or cracks), if neither the product nor parts of it have become loose or fallen off and if the function, safety and stability of the installation are unchanged. In case of doubt, a further series of test shots is carried out on the slightly modified areas. This would be the case with smaller dents, which would still be acceptable depending on their extent. However, it would be optimal if the test carried out was not visible on the product and if its functionality remained unchanged.
