NBN EN 947:1999

This European standard applies to all vertically hinged or pivoted doors. The standard specifies the method to be used to determine the permanent deformation caused when a vertical load is applied to an open door leaf fixed in its own door frame as part of a doorset. NOTE : Such downward forces that might reasonably be expected, such as a child swinging on the handle, should neither damage, nor impair the performance of, a door.
