National Standard GB/T8965-2009 “Flame Retardant Protection of Protective Clothing Part 1 Flame Retardant Clothing”

【Scope of application】: This instrument is suitable for testing the thermal insulation properties of flame retardant protective clothing fabrics exposed to radiant heat sources and convective heat sources. [Meet the standard]: National Standard GB/T8965-2009 “Flame Retardant Protection of Protective Clothing Part 1 Flame Retardant Clothing” 【Technical Parameters】: 1. Computer control, test results printed out. 2. Composition of heat source: 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. 3. Heat source heat flux range: ≤100kw/m2 4. Copper calorimeter measurement range: 0°C~100°C 5. Specimen size: 150×150mm 6. Gas medium: propane 7. Working power supply: AC220V/50Hz Power: ≤4.5kW 【Test methodology】： A heat source is placed on one side of the test specimen and a copper calorimeter is placed on the other side. Start the test, push and pull the clip into place, and when the sensor value reaches the limit of human secondary burn tolerance (the sensor temperature rises by 35°C~40°C), remove the clip from the heat source. From the intersection of the reaction curve and the human tissue endurance curve, the reading of the time leading to second-degree burns is accurate to 0.1
