Cable bundle burning test machine is a very mature product, the use of stainless steel, the whole by the following components: chamber, air source, ladders, emissions purification systems, ignition sources, implementation of standards GB / T18380.31-2008, IEC60332-3-10-2000 "cable and optical fiber cables under fire conditions - Part 31: bunched wire and cable vertical flame spread of vertically-mounted test equipment test reports" to meet the GB / T18380.32 -2008 / IEC60332-3-21: 2000 "and optical fiber cables - Part 32 burning test under fire conditions: vertically mounted bunched wire and cable vertical flame spread test AF / category R", (for more technical details contact phone : 13418813224 "woods") GB / T18380.33-2008 / IEC60332-3-22: 2000 "and optical fiber cables under fire burning test conditions Part 33: bunched wire and cable vertical flame spread of vertically-mounted test A Class" , GB / T18380.35-2008 / IEC60332-3-24: 2000 "cable and optical fiber cables under fire conditions - Test - Part 35: bunched wire and cable vertical flame spread of vertically-mounted test C class", GB / T18380. 36-2008 / IEC60332-3-25: 2000 "cable and optical fiber cables under fire conditions - Test - Part 36: Vertical mounted bunched wire and cable flame spread test Class D" 1, experimental apparatus 1.1 Test Chamber: experimental device should is a wide (1000 ± 100) mm, deep (2000 ± 100) mm and high (4000 ± 100) mm-standing cabinet. The back wall and sides of the chamber should heat transfer coefficient of about 0.7Wm-2K-1 thermal insulation, 1.5mm thick stainless steel plate USU304, intermediate coating 65mm thick mineral fiber insulation, outside of 1.5mm thick USU304 Stainless steel plate 1.2 Air Source: 1.2.1 Inlet is swift digital air gauge wind speed, air flow rate of gas (5000 ± 500) L / min. 1.2.2 After completion of the test: If you stop for an hour sample fire is still burning, equipped with alarm and use force to stop burning unit to rain 1.3 ladders type: wide (500 ± 5) mm wide standard ladders ( 800 ± 10) mm wide type ladders made of stainless steel bar 1.4 USU304 emissions of pollutants devices: 1.4.1 the upper chamber is equipped with digital anemometer ensure the wind velocity is less than 8M / S, will not affect the test chamber air traffic. 1.4.2 smoke dust collection and cleaning devices: SUS304 stainless steel with a diameter of 800mm height 3500mm. 2, ignition sources 2.1 Type: ignition source should include one or two belt type propane gas burner and Venturi flow meters and supporting mixer. Its surface for the fire should be drilled 242 flat metal plate 1.32mm diameter aperture from the center of these holes is 3.2mm, staggered in three rows, each row of 81, 80 and 81, respectively, located in nominal size in the range of 257 × 4.5mm. In addition, the flame side panels of the opening of a row of small holes, these guide holes remain stable combustion flame. Each burner should be equipped with an accurate means to control the inflow rate of propane and air. You can use rotameter or mass flowmeter 2.2 blowtorch ignition source location should be placed away from the front surface of the cable samples (75 ± 5) mm, from the bottom of the chamber (600 ± 5) mm, and the axis of symmetry and ladders. Torch for the fire point should be in the center of ladders between two rungs, and at least 500mm away from the lower end of the sample
