Comply with the standard: The fire resistance tester for paper surfaced gypsum board is a product developed according to the technical requirements for the determination of the fire stability of the latest national standard GB/T9775-2008 ISO6308 "Paper gypsum board" 6.5.15.

Features:

Reasonable structure design, high degree of automation of the control system, accurate recording time, stable performance, easy operation, automatic ignition function, digital display of temperature and time, is a good helper for your work.

Test principle: The sample is drilled and treated under specified environmental conditions. The sample was suspended in the middle of two fire vents with a strut, which was perpendicular to the specimen surface. Use liquefied petroleum gas as a heat source to supply gas to the two burners of the flammability analyzer. The burner orifice is 30mm from the plate surface. According to the standard, suspend the load under the specimen and light the burner. The thermocouple was used to measure the temperature at a distance of 5 mm from the plate surface. At the initial stage of the test, the carbonized protective face paper on the thermocouple should be removed without shaking the sample. Through regulation, the stability is controlled within (800±30) °C within 3 min, and this stability is maintained during the test. From the time the test piece meets fire, it is timed until the test piece breaks and breaks. Record the time for each test piece to be blown. Use the minimum value of five test pieces as the fire stability of the reorganization sample, accurate to 1 min.
