Single Cable Vertical Flame Tester

Single Cable Vertical Flame Tester is used for the vertical flame propagation of a single insulated wire or cable is a bench scale test to determine the resistance of a single cable to a 1kW flame application. It conforms to IEC60332-1-2 (flame propagation) and IEC60332-1-3 (test for flaming droplets).

Application

G233 Fabric vertical combustion tester is mainly used to evaluate the combustion characteristics of plastics and other non-metallic materials in fire. It is suitable for lighting equipment, low-voltage electrical appliances, household appliances, machine tools,electrical tools, electronic instruments, electrical instruments, electrical connectors and accessories and other electrical and electronic products and components of the research,production and quality inspection departments, but also suitable for insulation materials,engineering plastics or other solid combustible materials industry. In addition, it can also be used by the plastics industry, inspection departments and scientific research institutions.

Parameter

Technical Parameters

1.Stainless steel box, the height of 1300mm, width of 300mm, depth of 450mm.

2.Two stainless steel rods, can bind single wire cable or optical cable sample.

3.1KW mixed standard burner, can provide the standard test fire source.

4.Regulating gas and air flow rate of the rotor flow meters.

5.Pressure gauge and pressure relief valve to ensure that the pressure output is 0.1MPA.

Test Procedures

Prepare the cable to be tested and plug in the power cord, then turn on the power switch.

1.Secure the product to the fixed crossbar, adjust the height of the marking ruler, place the filter paper under the burning product, and turn on the gas (or propane gas) and compressed air. Set the burning time to the required number of seconds according to the cable diameter and standard settings. Tap the touchscreen to ignite, adjust the gas flow meter and air flow meter, and use the gauge to adjust the flame height: blue flame 50-60mm, outer flame 170-190mm.

2. Determine the number of burns required. Set the counter to 1 for one burn cycle.  The cycle will automatically stop after completion. For two burns, set the counter to 2. Press the black dot next to the counter to reset. The burning cycle will continue until the set number of times is reached and then automatically stop. Adjust the position of the Bunsen burner to ensure it is burning the product. Press the touchscreen to start the test or press the foot switch (automatic ignition). The burning time starts counting. When the burning time is complete, the Bunsen burner automatically extinguishes and the afterglow time begins. The test is complete after the afterglow time.

3. After the test, check the condition of the product.

4. Finally, press the exhaust button to vent the test exhaust gas outside.
