Fire test furnace building materials building materials flammability test furnace materials flammability tester building materials building materials building materials flammability tester flammability test device of flammability tester

A, an overview of the

Test before read national standard GB8626 building materials flammability test method, test work will be of great help to you.

JCK - type 2 building materials flammability test furnace is determined under specified conditions, whether building materials have flammability test method, GB8626 is according to the national standard of technical parameters and developed.

Second, the instrument working environment and main technical index

1. Ambient temperature: 15 ℃ to 25 ℃;

2. The relative humidity: 85% or less;

3. The power supply voltage and power: 50 hz, 220 v, 100 w;

4. Source: liquefied petroleum gas （LPG）;

5. The Bunsen burner on style fire time of 15 s;

Three size, style: the edge of the ignition 90 x 190 mm; Using surface ignition 90 x 230 mm, each set of tests need five specimens.

4, test steps

1. Check whether the time display setting of the instrument panel in the standard values.

2. Turn on the power supply, air supply, "gas switch valve on the instrument panel to the right to transfer to the minimum, open the cylinder valve.

3. Open the power switch, press the "reset" button to reset the burner.

4. The door is open burning, will be equipped with a specimen of the specimen clamp fixed to the burn in, press "run", according to the specimen of regulating specimen clamp distance with burner, then press "reset" button to make the back burner.

5. To the left with the ignition key on fire burner gas switch ", adjust the flame height to 20 mm + / - 2 MMM, the door is closed.

6. Press "run" button, make the burner on specimens flame for 15 s, after the flame, the burner automatically remove, measuring from ignition to reach the surface of the scale line or specimens flame burning flame of the time, press the "timer" key on the instrument panel display time stops, and record the data.

7. Repeat for five specimens after turn off the power supply, and the cylinder valve, gas switch "for combustion box, specimens for necessary maintenance.

8. "reset" : in the process of test not to 15 s, flame pointed to calibration, press the "reset" key to move to the burner.

Five, judgement of flammable materials

Tests comply with the following provisions of the building materials are indeed as combustible construction materials:

1. The bottom edge of specimen without protection, at the bottom edge of the ignition after 20 seconds, after the beginning of the five specimens flame point did not reach the scale line.

2. To the edge under protected specimen, in addition to the prescribed （1.）, should be attached a set of surface ignition test, ignition start after 20 seconds, five specimens flame point did not reach the scale line.
