Burning Dummy Test Method for Flame Retardant Clothing
The study of flame retardant clothing testing with dummy began in the 1960s, and the test standard for burning dummies was ASTM 1930-2000, "Testing methods for assessing the flame retardant properties of garments under fire conditions with dummy." In the 1970s, DuPont Company and the US Army jointly developed a combustion dummy test system, a thermal human instrument detection system, which mainly includes the following subsystems: propane gas storage and transport system; combustion management control system; Simulator system; data acquisition and analysis system; computer control system and corresponding operation interface; laboratory security system.
Using this experimental device, the situation in which the human body wearing the flame retardant clothing is completely immersed in the flame can be simulated under the condition of variable heat flow, and the test is used to predict the thermal protection performance of the real flame retardant clothing under the condition of flash fire. The fire field is produced by combustion of heptane gas with a heat flux density of 84 kW/(m2•s). The human body model wearing the experimental flame retardant clothing is placed in a laboratory simulated combustion environment and exposed for a certain period of time to observe the combustion. At the same time, through the 122 thermal sensors distributed on the human body model, the heat and temperature transmitted to the various parts of the human body surface through the tested flame retardant clothing are measured and calculated, and the total amount and position of the second and third degree burns of the human body are obtained. Evaluation of the thermal protection properties of flame retardant clothing.
NCTRF has made some improvements to the Burning Dummies. Enable the dummy to move in the fire. Place the dummy in the fire, and then simulate the action of the person to escape from the fire to move out of the fire at a specific time.
