12. Internal side hung, external side hung, and sliding doors and windows: 2 sets of anti-wear flexible clamps.
13. The opening angle of the door leaf can be set on the computer within the range of 70°-90°, and it also has the capability to set other opening angles. The equipment is equipped with an angle indicator with an accuracy of ≥2°.
14. Handle opening speed: adjustable.
15. Handle opening force: real-time display, with a maximum value settable.
16. Special design requirements (safety protection, etc.): 1. Safety protection measures shall be taken; 2. The size of the specimen opening shall be automatically adjustable, and the specimen frame shall be able to be raised, lowered, and laid down for specimen installation, with adjustable clamping force and opening angle.
17. Equipment material requirements: The support device for installing the test specimen should have sufficient rigidity to withstand the test load without causing damage to the joint parts of the specimen frame and door leaf, or deformation due to bending stress on the specimen.
18. The equipment is equipped with the function of automatically recognizing the status of the door leaf. When the door leaf fails to close in place within the specified time, the equipment should provide audible and visual alarms and suspend the test.
19. The equipment should have the function of real-time detection of opening force. When the opening force exceeds the set value, the equipment should provide audible and visual alarms and suspend the test. (The opening force of the door switch is available, but the opening force of the handle rotation is not).
