EN50575:2014 Wire Testing Equipment For Vertically Mounted Bunched Wires

IEC60332-3 Test apparatus for Vertical Flame Propagation of Bundles of Wires and Cables

Product description:

This equipment is a test device used to evaluate the ability of vertically installed bundles of wires and cables or optical cables to inhibit the vertical spread of flame under specified conditions. The equipment shell is made of all SUS304 stainless steel, and the whole machine is composed of: test box, air source, steel Ladder, emission purification system, ignition source and other parts.

Standards:

EN50575:2014,EN50399:2011

Device composition:

1. Test Chamber

The experimental device is a self-supporting box with a width of (1000±100) mm, a depth of (2000±100) mm, and a height (4000 of 100) mm. The back wall and both sides of the test chamber are made of thermal insulation with a heat transfer coefficient of approximately 0.7W, m-2K-1 (consisting of a 1.5mm thick SUS304 stainless steel plate, covered with a 65mm thick insulating mineral fiber), and an external wall. The door uses 1.5mm thick US304 stainless steel.

2. Air source

2.1 The air inlet is equipped with an air blower with adjustable air flow, and the air flow rate is (5000±500)L/mn to the combustion chamber. The air outlet is equipped with a digital anemometer.

2.2 After the test is completed: if the sample is still burning for one hour after the stop of the fire, an alarm is set and the device for stopping the combustion by the south force is used.

3. Copper ladder type

wide (500 ± 5) mm standard steel ladder width (800 ± 10) mm wide steel ladder made of SUS304 stainless steel bar exhaust purification device test chamber with exhaust fan on the top, the exhaust gas inside the box Withdraw the box at 6MS speed and send it to a smoke collection tower with a digital display anemometer.

4. Emissions purification device

4.1 The upper part of the test box is equipped with an exhaust fan, and the box type exhaust gas is pumped out of the box at a speed of 6M/S. The smoke collection tower is sent out, and the exhaust vent has a digital anemometer.

4.2 Smoke collection and washing Dust and dust devices (See DX-349A Spray Gas Absorption Tower): Internal acid and alkali resistant plastics, 800mm diameter, 4000mm height

5. Ignition source

5.1 Type: The ignition source shall include one or two band-type propane gas burners and their associated flow meters and venturi mixers. The surface of the fire supply should be 242 flat metal plates with a diameter of 1.32 mm. The center distance of these holes is 3.2 mm and they are staggered in three rows with 81, 80 and 81 rows respectively. The size is in the range of 257×4.5 mm. In addition, a row of small holes are opened on both sides of the fire board. These guide holes can maintain the stable combustion of the flame in accordance with GB/T 18380.31-2008 torch requirements.

5.2 Each torch is equipped with a rotameter or mass flow meter that can accurately control the flow of propane and air. Propane flow meter: 3-30umin2.5 class, air flow meter: 10-100umin 2.5 class 53 pilot source position Place horizontally, (75 ± 5) mm from the front surface of the cable specimen, (600 ± 5) mm from the bottom of the chamber, and the axis of the copper ladder is symmetrical. The torch fire point should be centered between the two crosspieces of the ladder and at least 500 mm from the lower end of the specimen.

Technical parameters:

Internal dimensions of the combustion chamber	1000mmX2000mm x 4000mm(wdh)
Steel ladder size	500mm × 3500mm(w*h), wide type 800 × 3500mm
With a type torch	in line with GB/T18380.31-2008
Venturi mixer	in line with GBT18380.31-2008
the air flow adjustment in the combustion chamber	4500-500L/min
Propane flow regulation	3-30L/min
Compressed air flow regulation	10-100L/min
Anemometer	0.05-5m/s
Digital thermometer	0～400℃
With the type of torch positioning	high 600 ± 5mm,any adjustable horizontal distance
