Hinged or pivoted doors — Determination of the resistance to static torsion

ISO 9381:2005 applies to all vertically hinged or pivoted doors.

ISO 9381:2005 specifies the method to be used to determine the permanent deformation caused when static stress in torsion is applied to an open door leaf fixed in its own door frame as part of a doorset.

ISO 9381:2005 can also be used in respect a door leaf submitted for test in a frame which the manufacturer considers appropriate to and typical for the intended utilisation.
