— The lacks of operating standards and measurement methods make the universal design of the door difficult to achieve. Thus, in this study, a force measurement system for hinged door operation has been developed, and a series of operating force measurement for hinged door were carried out with and without door closer. Specially, a quarter arc guiding track was designed to confirm that the door required operating torque could be measured successfully. The results showed that as door closers were applied, the operating forces increased greatly. There were two characteristic measuring signals composed of the initial force and the maximum force existed significantly. The use of the door closer was proved to increase the required operating torque greatly, which even caused inconvenience for users. Regardless of whether use a door closer or not, the consideration of door operating torque in the universal design was proved to be decisive.
— Required operating torque, force measurement system, door closer.
