Introduction to the Burning Man System

The burning man system/burning dummy system is mainly composed of burning dummy, data acquisition device, flame generation and control device, skin heat transfer model and burn assessment model, as well as system centralized control and application software platform. The design principle is to test the change of the surface temperature of the dummy by simulating the thermal exposure process of the dressed human body in the burning flame, and to estimate the second-degree, third-degree burns and the percentage of the total burn area that may cause the skin. The worse the flame retardant protection performance.

product description:

The burning man system/burning dummy is used to objectively and scientifically evaluate the protective performance of special clothing such as military uniforms, fireproof clothing, fire-fighting clothing, flame retardant and high temperature resistant work clothing, and the burning dummy system is at the forefront of the intersection of clothing science and biophysics* Technology is currently recognized as an objective and comprehensive means of evaluating the overall thermal protection performance of clothing. There are 135 high-temperature sensors evenly distributed on the surface of the burning dummy, and the joints of all parts can be moved, which can simulate various dressing postures of the human body.

Burning Dummy Research:

Retrieve relevant domestic and foreign information, use non-metallic materials to make the burning dummy body, the duration of the flame during the clothing test is generally 4 s, and the surface of the dummy may need to withstand the burning flame of up to 300 ℃. Therefore, the dummy body material must be 300 °C It has good thermal stability under short-term combustion flame above ℃, and can withstand harsh fire environment; the response of the sensor arranged on the surface of the dummy to the combustion flame should be close to the response of human skin to the combustion flame; the data acquisition and processing device can Fast acquisition of dummy surface sensor data.
The burning man system/burning dummy system is mainly composed of burning dummy, data acquisition device, flame generation and control device, skin heat transfer model and burn assessment model, as well as system centralized control and application software platform.
Dummy body:

According to the above design requirements, through comparative analysis of the physical properties of high temperature resistant materials, polyimide with the highest temperature resistance grade, mechanical properties, dielectric properties and corrosion resistance properties is selected as the main material of the combustion dummy body. According to the dummy model The appearance characteristics of the dummy body are manufactured according to the following process: synthesizing polyimide → curing resin material → making molds for each anatomical segment of the human body and high temperature molding → vacuum curing → surface treatment.

product description:

Used to test the overall thermal protection performance of protective clothing. The complete combustion dummy system consists of combustion chamber, combustion dummy and air supply control system.

standard test:

EN ISO 11612, EN ISO 11611, ISO 13506, EN469:2005 etc. are applicable to this test system.

Sensor layout:

Considering factors such as dummy area, data collection, burn assessment calculation, etc., 120 adiabatic copper sensors are evenly arranged on the dummy surface. When installing the sensor, use a milling cutter to drill holes according to the diameter and depth of the copper sheet to ensure that the surface of the sensor and the surrounding textile guide standard and test circle are closely matched with the dummy body, and the distribution of the sensor is uniform.

Choice of fuel:

Comparative analysis of the physical and chemical properties of commonly used clean and combustible gases. Propane comes from a wide range of sources. It forms water vapor and carbon dioxide after combustion. It is an environmentally friendly fuel. It has high combustion calorific value, low boiling point and good safety. For laboratory use, propane was selected as the fuel for the test system.


After years of practice, we have accumulated rich experience in equipment sales, installation and commissioning, and have become a trusted partner of our customers. The Shanghai Branch of the Qinsun has shown excellent quality in the sales and service of textile testing instruments and leather testing instruments and materials, and has been recognized by the majority of customers.
