This instrument is suitable for testing the thermal insulation performance of flame-retardant protective clothing fabrics exposed to radiant heat sources and convection heat sources.
Second, the test method
Place a heat source on one side of the test sample and a copper calorimeter on the other side. Start the test and the sample clip is pushed into place. When the sensor value reaches the endurance limit of the second grade burn (the sensor temperature rises 35°C to 40°C), remove the sample clip from the heat source. From the intersection point of the response curve and the human tissue tolerance curve, the time for the second-degree burn was read to the nearest 0.1 second.
