Implementation standards and operating instructions for building materials flammability test furnace
Building materials flammability test furnace implementation standards: The building material flammability tester device meets the technical specifications and requirements specified in the national standard GB/T8626-2007, and is suitable for judging whether the building materials have flammability test under the specified conditions. Building materials flammability test furnace operating procedures 1. Cut the sample using a template of 250 mm x 90 mm. If the sample is a melt shrinkage product, a template of 250 mm x 180 mm is used. 2. Clamp the sample into a sample holder with a size of 250 mm × 90 mm, tighten the butterfly, and fix the sample. The size of the melt shrinkage product sample holder is 250 mm x 180 mm. At this time, the sample holder should not be attached to the horizontal rod. 3. Turn on the power switch and set the ignition time to a little longer, such as 5 minutes. According to the ignition mode, select the corresponding positioner, and start the test. After the burner stops at the 45° position, insert one end of the positioner into the burner. At this time, the sample is clamped to the horizontal rod, and the upper and lower positions of the sample holder are adjusted to meet the test requirements. Remove the positioner. Press the back button. After the burner is reset, it is cleared by test. 4. Press and hold the ignition button, and adjust the flame adjustment valve on the instrument panel. After the gas is applied, adjust the flame height to 20 ± 1mm. Adjust the flame from major to hour. It is best to first turn the flame adjustment knob on the panel. Tight, it is easier to adjust the flame. The height of the height gauge is 20mm. Close the front door. 5. Place two filter papers in the collection tray and place them under the specimen. 6. Set the ignition time. According to the test start, the burner will automatically turn to the 45° position, and stay at the set ignition time, then reset, and the afterburning time will start. After stopping the continuous combustion before the sample continues to burn until the tick mark is reached, press the continuous combustion stop or the sample continues to burn until the tick mark is reached. Record the burning time. 7. Clear the test according to the test and stop the test. If you want to continue the test, you can repeat the above steps, otherwise turn off the power supply, provided by Shandong Textile Institute.
