  • A device for meauring torque rating of bottle cap torque-meters was developed. The device includes a special check lever, a force weight loading mechanism, and a horizontal to vertical loading mechanism. The torque rating was measured by multiplying the force value of the weight and the arm length of the check lever. Factors affecting measurement uncertainty were analyzed and the uncertainty in the measurement results of the torque rating was evaluated. The results showed that the performance of the device was stable and reliable. It can be used to calibrate bottle cap torque-meters of level 1 or below and small range special torque testers, providing traceability for their torque indication.
