3. Vertical Flame Test / Burning Test Principle

Vertical flammability tester is used for sample vertical flame test by burning it in its vertical end. In the specified combustion chamber, under the specified ventilation conditions, use the flame generated by the specified nozzle to ignite the center of the bottom edge of the sample clamped by a standard fixture in the vertical direction. flame. Record the continuous burning time of the flame on the sample, that is, the continuous burning time, and record the time that the material continues to burn without flame, that is, the smoldering time. The maximum length of the damaged part of the recording material under the specified weight tension is the damaged length.
