Introduction:

Protective Clothing Against Heat and Flame Tester conforms to ISO13506 and ASTM F1930 standards.

To empirically evaluate the performance of a garment in a simulated flash fire environment that controls the heat flux, flame distribution and duration of the flame test manikin.

The Instrumented Manikin Flame Engulfment Test Equipment can be used to analyze the burn range and measure the time of 2nd and 3rd degree burn using this system.

About System:

Protective Clothing Against Heat and Flame Tester is mainly composed of test chamber,control system, manikin, data acquisition system, image acquisition system and software. It can calibrate the uniformity of incident heat flow, collect and calculate the temperature of epidermis, dermis and subcutaneous tissue, complete the analysis of first degree burn, second degree burn and pain, predict the degree and scope of burn, so as to complete the protection clothing definition of protective properties.

Manikin:

• Protective Clothing Against Heat and Flame Tester meets the requirements of ISO 13506 and ASTM f1930, and the manikin size meets the requirements of ASTM D6240;
• The manikin model is made of non degradable and fireproof ceramic composites;
• The manikin has joints of shoulder, elbow, knee and ankle;
• The connecting cable is connected into the manikin body from the top of the head or the back neck;
• 122 sensors were distributed throughout the manikin;

Sensors:

• The sensor is made of copper alloy, and thermocouple is welded on the back of sensor to measure the temperature change of copper plate;
• The thermal radiation range is at least 0-167kw / m2;
• The sensor surface is sprayed with black high temperature resistant paint;
• The response time of thermal sensor is less than or equal to 0.1s;

Test chamber of Protective Clothing Against Heat and Flame Tester:

• The test chamber is constructed of fire-resistant quartz glass and steel structure. The volume of chamber is 4m long x 3.5m wide x 3m high;
• The chamber provides a uniform flame for the test surface of the manikin and provides sufficient space for debugging;
• The chamber shall be provided with independent ventilation equipment to ensure sufficient oxygen supply during the test, and exhaust gas shall be drained after the test;
• The exhaust rate of fan is adjustable, and the exhaust air volume is at least 25m3/min; it can also provide cooling air with smaller exhaust air volume;
• Combustible gas leakage detector and door opening and closing detector are equipped in combustion chamber to ensure personnel and test safety;

Control system of Protective Clothing Against Heat and Flame Tester:

• 12 imported burner were used and divided into 6 groups, 2 in each group
• The burner array is composed of hexagonal layout to provide uniform incident heat flow of at least 84kw / m2 for the manikin surface;
• The gas pipeline is arranged with stainless steel pipe, and the flame retardant hose is used to connect with the burner group;
• The inlet explosion-proof solenoid valve controls the gas on-off, and the response time is 0.1s;
• The gas flow is controlled by mass flow controller to accurately control the gas flow to ensure the stability and repeatability of the fire site;
• The burner is equipped with a long open fire igniter for safe pilot fire. During the pilot fire test, the combustion state is maintained throughout the whole process to ensure the ignition safety;

Data acquisition system of Protective Clothing Against Heat and Flame Tester:

• Computer + Labview realizes multi-channel high frequency data sampling and analysis system;
• Adopt imported brand data acquisition platform and Ethernet connection to realize time synchronization distributed measurement;
• The imported brand temperature acquisition module is adopted, the sampling frequency is 95Hz/channel, the sampling accuracy is ± 0.29 ºC, and the resolution is 0.01 ºC;
• Using Labview software platform to achieve synchronous data acquisition, display and record;
• 124 sensors and temperature environment data are collected synchronously;

Software of Protective Clothing Against Heat and Flame Tester:

• The system test software adopts Labview editing, modular design, simple interface and rich data content;
• The temperature and heat flow of each channel can be calibrated, and each channel sensor is equipped with a correction curve;
• The Instrumented Manikin Flame Engulfment Test Equipment adopts 2nd degree burn calibration of sensor;
• The gas flow of each channel can be set;
• Exposure condition calibration: the manikin with sensor calibrated is placed in a blast environment to confirm the heat flux value, average value and standard deviation of each channel;
• 2nd degree burn area analysis of manikin surface;
• 3rd degree burn area analysis of manikin surface;
• Total burn area analysis of manikin surface;
• Total heat absorption analysis of manikin surface;
