Eniso11612, Eniso11611, ISO13506, EN469: 2005
Combustion dummy test system for testing the overall thermal protection of protective clothing performance.Product Details:
Complete combustion dummy system, composed of a combustion chamber, a combustion dummy, and a gas control system.
Test standard Eniso11612, Eniso11611, ISO13506, EN469: 2005, etc. are applicable to this test system.
The combustion dummy test system is a test system that is controlled as a core, composed of a combustion dummy, a thermal sensor group, a flame generating device, a computer control module, a data acquisition and processing module, and a burn analysis module. . The first four parts are mainly implemented by the corresponding hardware, and the next four parts are solved by software programming and establish models.
The combustion dummy model adopts 1: 1 adult male model, the material is stable, the flame inert, the strength of high strength is 2 to 3 mm, the surface area is 1.72m2; in the head of the dummy model The torso, leg and arm tableare evenly distributed with a number of sensors; and sprayed black flame retardant high-temperature paint in the outer surface of the dummy model; in the head of the dummy, there is a processed sensor data The derived line makes the instrument to collect and process the data signal.
The sensor group includes a thermal sensor and a pressure sensor. The thermal sensor consists of 120 heat flow sensors, which is uniformly distributed in the dummy surface, and each sensor represents a physical condition for a certain surface area; each sensor is numbered, if the temperature value calculated by the sensor Burn estimates to satisfy the second, three degrees of burns, and labeled it into the simulated digital human body model by different colors. Since the temperature change of the flame is a dynamic process, the test sensor temperature range is high, the response time is short to achieve the dynamic changes of the flame. The pressure sensor is mainly used to measure the gas pressure value in the gas container and the gas pipeline, and ensure the safety and controllable experiment.
The fire generator consists of 12 propane flame generators surrounded by 6 groups. Each set of flame generators consists of a flame nozzle and guiding flame that adjusts flame sized by high pressure liquefied gas tanks, buffer tanks, pressure pipes, and gas pressure sensors. The flame action time generated by the flame generating device is controlled by a computer control analog module, and the flame intensity remains uniformly stable. The computer control module consists of pre-prepared software. Its main role is to automatically check the various sets of sensors related to the experiment before the start of the experiment.Status, and in the stateless instructions, the ready-ready instruction; in the experiment, the computer control program controls the action time and intensity of the flame generator, and automatically boot the data processing module to record data variations of each sensor; in the experimental results stage,Save the recorded data into the form of a file and guide the exhaust gas ventilation system to cool the combustion experimental warehouse.
