The mechanical performance of a door is classified into various stress groups according to DIN EN 1192. The “hard impact” provides information about the surface impact resistance – an important indicator for the resistance of the door surface to daily wear and tear.
The “soft impact” simulates stress caused by body impact on the door. In these tests the general door construction as well as the hinges are of significant importance. The multiple function test is conducted to ensure that all door elements withstand the dynamic stress of thousands of use cycles.
Lock and hinges are particularly stressed. However, the whole door construction and extras such as glass panes are of special interest, too. The mechanical performanceof certain components – e.g. withdrawal of screws and hinges – is just as important as the checking of complete door constructions.
