Application
It is used for mensurating plasterboard stability in case of fire, can also be applied to other building materials, decoration, decoration materials, fire prevention performance measurement.
Test Introduction
It is introduced drilling and processed under prescribed conditions. Suspend the sample between the two fire nozzles with a support rod, making the fire nozzles perpendicular to the surface of the sample. Liquefied petroleum gas is used as the heat source to supply gas to the two burners of the fire stability tester. The distance between the burner nozzle and the plate surface is 30mm. Suspend the load at the lower end of the specimen as per the standard and ignite the burner. Measure the temperature at a distance of 5mm from the plate surface using a thermocouple. At the initial stage of the test, the carbonized protective paper that has fallen onto the thermocouple should be removed without shaking the sample. By adjustment, the temperature was controlled at (800±30) ℃ within 3 minutes and maintained at this temperature throughout the test. Start timing from the moment the specimen is exposed to fire until it breaks and fails. Record the time it takes for each specimen to be burned off, and take the minimum value among the five specimens as the fire stability of this group of specimens, accurate to 1 minute.
