Abstract
In this article, the maximum pushing and pulling forces of 750 persons between 20 and 30 and over 50 years of age are presented. Measurements were done using a framed strain gauge transducer and recorder. Both forces were measured in a free standing position that was related to opening a heavy door. The latter makes it possible to use the information in a standard on emergency exits. Such a force standard is not available in The Netherlands. We propose an addition to NEN 6082:19971 concerning human abilities to open unfastened, hinged doors that are on an escape route.
