A device and method are disclosed for evaluating closing performance of a door in which the door engages an engagement element included in the device which is detachably mounted to fixed structure adjacent the door and which is moved by an opening movement of the door. An elastic element such as a spring is deflected by the motion of the engagement element to generate elastic potential energy which is detected and shown by a detector/display so that the point of release of the door is determined when the potential energy reaches that corresponding to a predetermined minimum mechanical energy level. The door is then swung in a closing direction by the potential energy stored in the elastic element and it can be immediately determined if the door closure performance is met by the door becoming fully closed. |
