Abstract
The utility model relates to a novel thermal protective performance testing and evaluating device of thermal protective equipment, which comprises a combustor, a quartz lamp tube, and a copper sheet heat-flow meter and a computer recorder which are connected with each other. The combustor and the quartz lamp tube are arranged right below a tested fabric. A frame is arranged above the tested fabric and consists of a transverse plate and two side plates, wherein the transverse plate is suspended and supported between the two side plates and is movably connected with the two side plates. The copper sheet heat-flow meter is placed on the transverse plate. An air layer between the copper sheet heat-flow meter and the tested fabric is connected with a micro humidifier. A temperature-humidity sensor is placed in the air layer and is connected with the computer recorder. The novel thermal protective performance testing and evaluating device can overcome the defect that the impact of the thickness and the humidity of the air layer below clothes on the thermal protective performance is neglected by the existing testing and evaluating device, and can really simulate the situation of burns on a fire scene.
