【Scope of application】: It is suitable for the requirements of the national standard GB 8965-2009 “Protective clothing – flame retardant protection” test method, and can be used to determine the thermal protection performance of flame retardant fabrics. It is suitable for the different requirements of textile and clothing, petrochemical, labor safety protection and quality supervision and inspection and other industries and institutions for the thermal protection performance test of protective clothing, and provides a scientific and reliable basis for the development of flame retardant protective clothing, quality control in the production process and the testing of thermal protection performance in the use of flame retardant protective clothing. [Method standard]: GB8965-2009、NFPA 2112、ISO17492、ASTM F2703 [Instrument features]: 1. Flame retardant material samples are placed horizontally and at a certain distance from the convection/radiation mixed heat source, and the time of exposure is recorded when the transmitted heat is equal to the secondary burn that causes human tissue. According to the different placement positions of the sample and the test sensor, direct contact is used to simulate the contact between the flame retardant protective clothing and the body, and the interval of 6.5mm is used to simulate the situation where there is a certain space between the flame retardant protective clothing and the body. 2. It is mainly composed of PLC, heat source, copper calorimeter, digital display, system operation software, etc. PLC: Control the coordinated action of all components (heat source, heat insulation plate, specimen holder, etc.), and communicate with the operation software to complete the command action. 3. Heat source: Provide heat flux that can meet the needs of the test. 4. Copper calorimeter: A copper calorimeter specially made according to the standard requirements, which is tested by thermocouple. 5. Digital display: display the temperature of the copper calorimeter thermocouple; The system reads heat from the digital display via RS485 communication. 6. System operation software: realize the control of the test process; The test curve is drawn according to the test data, and compared with the secondary burn curve of the human body, the burn time is determined and the test results are obtained. 【Technical Parameters】: 1. Heat source composition: 1 group of radiant heat sources and 2 convective heat sources. The radiant heat source consists of 9 T-150 infrared quartz lamps. The convection heat source consists of two Meck lamps. 2. Heat source heat flux range: ≤100kw/m2 3. Copper calorimeter measurement range: 0°C~100°C 4. Specimen size: 150×150mm 5. Gas medium: propane 6. Working power supply: AC220V/50Hz power: ≤4.5Kw
