【Product Overview】:
With the revision of GB8965.1-2020 standard, the flame retardant performance under the condition of finished product detonation is used as a mandatory indicator, and the dummy detonation test system is developed according to ASTM F1930, ISO13506, GB/T23467 and other standards, mainly composed of gas supply system, combustion system (6 groups of 12 burners), dummy system, test system, safety protection system, etc., simulating complex fire situations, testing the thermal protection performance of clothing, and can effectively evaluate the overall thermal protection level of clothing. With this test service, the dummy detonation test system was validated.
The system has high scientific and technological content and product added value, which can not only highlight the R&D level and comprehensive strength of enterprises in the field of security, but also serve as a new economic growth point in the mechanical and electrical sector to help enterprises achieve high-quality development. Dummy detonation test system test.
【Scope of application】：
The burning dummy test system simulates the human body (dummy), the heat exposure process in the burning flame, tests the change of the surface temperature of the dummy, estimates the possible second- and third-degree burns of the skin and the percentage of total burn area, and accurately predicts the degree of body skin burns. In the high-simulation simulation of the high-risk environment of the fire scene, the combustion dummy test system can be used to evaluate the flame retardant performance of various protective equipment such as firefighting clothing and military uniforms and study the influencing factors.
【Compliance with standards】：
ASTMF1930—2000，ISO13506—2008，GB/T23467-2009，GB8965-2020
【Technical Parameters】:
1.
Combustion laboratory system
1. The combustion test chamber adopts an integral fireproof structure, which is composed of metal frame and flame retardant materials.
2. The effective dimensions of the combustion test chamber are 4.0m (length), ×4.0m (width× 3.0m (height), (the height of the construction space is required to be at least 4m, and the construction area is at least 50m).
2）
3. Ventilation and exhaust system
The test chamber is equipped with a pre-designed fan, which can automatically adjust the air volume for ventilation and exhaust according to different stages of the experiment, that is, it can ensure the ventilation and oxygen supply in the box during the test, and can quickly discharge the exhaust gas in the box after each combustion, and supplement the cooling air after the data is obtained.
2. Boom and safety control system
1. Burner: 6 groups of 12 burners
2. Gas transmission system:
Fuel delivery systems such as propane gas lines, pressure regulating valves, valves, and pressure sensors are used to transfer gaseous propane to the ignition system and combustion flamehead. The fuel delivery system can provide sufficiently uniform and consistent heat flow with a heat flow density of at least 84kw/m² and a fuel delivery time error of ±0.1s.
3. Safety and security system: gas detector, door seal detector, flame detector, fire extinguisher, emergency stop device and other necessary safety systems.
3. Combustion dummy system
1. The real form and size of the burning dummy are based on height 1. 8 meters of adult males are the standard, and the dummy is composed of head, chest, back, abdomen, arms, hands, legs, feet, etc. The dummy model shell is made of non-metallic materials that are completely fireproof and have good thermal stability (specific specifications can be customized)
2. The manikin joints are adjustable and can be posed in various postures to meet the requirements of customers for special position testing of clothes. (DR666-40RC only)
3. Heat flow sensor The heat flow sensor is installed on the body surface of the model, which can accurately test the change of surface temperature of the dummy.
DR666-40R type 130 pieces
DR666-40RCtype146Only(Includes separate head and hand test areas)
4.3DMeasurement system{DR666-40RC only)
The three-dimensional digital measurement technology of human clothing is used to measure the shrinkage rate of clothing before and after combustion
5. Computer centralized control system and application software platform
The self-developed software system is used to realize the whole experimental process is fully controlled by computer, and the data collection and analysis are automatically completed by the computer.
