Main features:

1. Experimental device

A) test case: the experimental device should be a self-supporting cabinet with a width (1000 + + 100) mm, deep (2000 + / 100) mm and height (4000 + + 100) mm.

B) the heat transfer coefficient of the rear wall and both sides of the test case shall be about 0.7W? M - 2? The thermal insulation of k-1, 1.5mm thick of the USU304 stainless steel plate, the middle coated 65mm thick insulation mineral fiber, the external is 1.5mm thick of the USU304 stainless steel plate.

2. Air source:

A) the air inlet is equipped with the digital air speed velocity meter, and the air flow rate is (5000 plus or minus 500) L/min;

B) after completion of the test: if the fire is stopped for an hour while the sample is still burning, there is an alarm and a device used to stop the burning in the rain.

3. Type of steel ladder: width (500 + + 5) mm standard steel ladder width (800 + 10) mm wide steel ladder material is made of normal 304 stainless steel;

4. Discharge cleaning device:

A) the upper part of the test box is equipped with a digital anemometer to ensure that the velocity of the wind is less than 8M/S, which will not affect the air flow in the test box;

B) smoke collection and dust cleaning installation: use SUS304 stainless steel with a diameter of 800mm and a height of 3500mm.

5. Ignition source:

A) type: the ignition source shall include one or two belt propane gas jet lamps and their supporting flow meter and venturi mixer. The surface for fire shall be the drill has 242 diameter of 1.32 mm diameter of flat metal plate, the center distance of hole is 3.2 mm, there are three rows of staggered, 81, 80 and 80 respectively in each row, in nominal size is 257 * 4.5 mm range. In addition, a row of holes are opened on both sides of the fire board, which can keep the flame stable and burning.

B) each burner is equipped with an accurate device to control the flow rate of propane and air. The rotor flow meter or mass flow meter can be used.

6. Ignition source location:

A) the spray lamp should be placed horizontally, the surface of the cable sample (75 plus or minus 5) mm, the bottom of the test box (600-plus or minus 5) mm, and the symmetry of the steel ladder axis. The burner shall be at the center of the steel ladder between the two transverse gears and at least 500mm from the bottom of the sample.
