The combustion dummy test system is used to test the overall thermal protection performance of protective clothing. The complete combustion dummy system consists of a combustion chamber, a combustion dummy and a gas supply control system.
The duration of the flame of the burning dummy body when used in clothing testing is generally 4 s. The surface of the dummy may need to withstand a burning flame of up to 300 ° C. Therefore, the material of the dummy body must have a short-term burning flame above 300 ° C. Good thermal stability, can withstand the harsh fire environment; the response of the sensor on the dummy surface to the combustion flame should be close to the human skin's response to the combustion flame; the data acquisition and processing device can quickly collect the dummy surface sensor data.
The system is mainly composed of a burning dummy, a data acquisition device, a flame generation and control device, a skin heat transfer model and a burn evaluation model, and a system centralized control and application software platform. The design principle is to simulate the thermal exposure process of the human body in the burning flame and test the change of the surface temperature of the dummy. It is estimated that the second and third degree burns of the skin and the percentage of total burn area may be caused. The worse the flame retardancy protection performance.
