NBN EN 950:1999

This standard applies to all door leaves. The standard specifies the method to be used to determine the damage caused to a door leaf by the impact of a hard body. Note: Such impacts, that might reasonably be expected from contact with small objects or parts of larger objects such as corners on furniture or footwear, can produce local surface failures affecting both strength and appearance. The kind of damage caused by impact can vary with the material used in the door construction.
