Test box: The experimental device should be a self-standing box with a width of 1000mm, a depth of 2000mm and a height of 4000mm. The bottom of the box should be 300mm above the ground. The perimeter of the test chamber should be sealed, the air from the bottom of the chamber from the front wall (150±10) mm to open a (800±20) mm x (400±10) mm air inlet into the box. A (300±30) mm x (1000±100) mm outlet should be opened at the back of the top of the chamber. Test chamber should be used on both sides of the heat transfer coefficient of about 0.7W.m-2.K-1 thermal insulation, the distance between the steel ladder and the back wall of the test chamber is (150±10) mm, and the bottom rung of the steel ladder is (400±5) mm from the ground. The lowest point of the cable sample is about 100mm from the ground.

1.Ignition source type: including one or two band-type propane gas blowtorches and their matching flowmeters and Venturi mixers. The ignition surface is drilled with 242 flat metal plates with a diameter of 1.32mm. The center distance of these holes is 3.2mm, arranged in three rows in a staggered arrangement, each row is 81, 80 and 81, distributed in the nominal size is 257×4.5mm. In addition, a row of small holes are opened on both sides of the flame board, and this guide hole can maintain the stable combustion of the flame.

2.Ignition source location: The torch should be placed horizontally, (75±5) mm from the front surface of the cable sample, (600±5) mm from the bottom of the test chamber, and symmetrical to the axis of the steel ladder. The flame supply point of the blowtorch should be located in the center between the two crossbeams of the steel ladder, and at least 500mm away from the lower end of the sample. The center line of the blowtorch system should be approximately the same as the center line of the steel ladder.
