1, the peak impact force should not exceed 6kN;
2. The extension length or fall distance should not be greater than the value of the product identification;
3, should not appear ribbon tear, open wire, broken pieces of metal, open the connector, rope off, analog people slip, buffer (rope) off phenomenon 4, after the crash stopped, the simulation is not suspended in the air There should be a simulation of head-down phenomenon;
5. After the fall and fall, the seat belt should not exhibit obvious asymmetric slip or asymmetrical deformation;
6. After the crash stops, the connecting point of the safety rope with the main belt should be kept on the back or waist of the simulated person when the simulated person is suspended in the air, and should not be slid to the underarm and waist;
7. After the crash stops, the simulated person's armpits and the inside of the thighs should not have metal parts when they are suspended in the air;
8. After the crash has stopped, the simulator should not have any components to oppress the simulated human throat when it is suspended in the air.
