As a type of protective equipment, the mechanical properties of seat belts and safety ropes are crucial. The national standard GB/T 6095-2009 specifies their testing methods, with the universal testing machine being the main testing equipment. The static load test of seat belts and safety ropes uses a universal material testing machine with a range generally less than 50kN and an accuracy level of 1. The inspection method for seat belts using a tensile testing machine is to
