RAL - GZ 426/5
“Impact resistance of edging” refers to the impact resistance of the vertical edging of the door leaf.
Generally, the edging is only subjected to the impact stress of hard objects (e.g. suitcases, walkers, service trolleys, etc.).
During the test, a steel ball is dropped from a defined height onto the edging (ball drop test).
The extent of any damage is used for categorisation into defined usage classes.
