The automobile wire flame retardant testing machine is called the 45 ° combustion tester, 45 ° flammability tester, 45 ° harness combustion tester, automobile wire flame retardant testing instrument, 45 ° combustion tester, 45 ° combustion testing machine, and other names.

The TG-25085D automotive wire flame retardant testing machine is based on the standards GB/T25085-2010 "Road Vehicles 60V and 600V Single Core Wires" and the international standard ISO 6722:2006/SAE-J 1128-2005，QC/T730-2005，DIN 72551；A 45 ° automotive wire harness combustion testing device developed and produced according to parameter requirements.

TG-25085D Automotive Wire Flame Resistance Testing Machine Function Implementation: Used to measure the flame resistance performance of 60V and 600V single core wires for road vehicles. The sample fixture is equipped with an elastic adjustment mechanism, which can easily clamp and tighten the sample; The sample maintains an angle (45 °+1 °) relative to the vertical line. The shortest distance between any part of the sample and the combustion chamber wall is 100mm. The straightening stroke of the wire harness clamp (mm) is ≥ 10mm.

Technical parameters of TG-25085D automobile wire flame retardant testing machine：

1: Flame height adjustment range: (10-100) mm. Place a collection tray under the sample fixture to collect molten droplets during sample combustion.

2: Fire supply time: 0.1-999.9S continuous setting, the flame can continuously burn the sample within the set time and can automatically reset to zero

3: Time display resolution: 0.1s

4: Gas lamp: Flame application and control mode: automatic ignition, automatic control time

5: Combustion tube inner diameter: 9mm, the temperature of the internal blue flame cone reaches (950 ± 50) ° C, and the length should be 50mm

6: Sample holder: Sample fixture clamping range (mm): ≥ 600 * (φ 0.3- φ 17.0)

7: Ventilation hood: The box has good airtightness, effectively avoiding the harm of smoke and harmful gases generated by the combustion of the test sample to the test personnel during the test process. The observation window is equipped with a large tempered heat-resistant glass window for easy observation of the test process. LED standard lighting fixtures are used, with bright illumination and easy replacement

8: Gas detection and control system: The gas detection and control system has the functions of gas leak detection, sound and light alarm, and automatic cut-off of gas source

9: Exhaust and smoke exhaust device: After the test is completed, the high-power exhaust fan forcefully exhausts the smoke generated by the combustion of the sample quickly, while also rapidly reducing it

10: Outer box size: length 1200 x width 650 x height 1500mm, exhaust hole Φ 100mm;

11: Power supply: 0.5kVA 220V 50-60Hz

Instrument structure:

The instrument mainly consists of an electrical control box, a combustion test box, a Bunsen burner, a burner base, an electromagnetic valve, a high-pressure igniter, a timer, a signal control line, a sample holder, a fuel bottle, a smoke exhaust system, etc..

Equipment features:

1: Use one set of local lamps and one set of sample fixtures.

2: There are two timers for recording time: combustion time and residual flame time..

3: Set the combustion time, the combustion time will be automatically timed, and it will stop automatically when it arrives..

4: After the combustion time stops, it will automatically jump to the residual flame time and automatically time, stop by clicking, and remember

Record data frozen on the display screen.

5: Real time gas monitoring is conducted on combustion testing equipment and testing sites to effectively ensure equipment and personal safety. The pressure reducing valve of the liquefied gas tank has the function of detecting the pressure of the gas pipeline. When the gas hose is accidentally disconnected and the gas pressure drops sharply, the pressure reducing valve will automatically shut off the gas source. After troubleshooting and connecting the gas hose, press the pressure reducing valve button to connect the gas source.

Instructions for use:

Suspend the sample at a 45 degree angle inside the combustion chamber, with the top of the flame cone aligned with the sample. Apply flames at a distance of 100mm above the lower end of the wire and 500mm ± 5mm below the upper end. For wires with a nominal cross-sectional area not exceeding 2.5mm, the flame will automatically extinguish after 15 seconds of being applied to the wire; For nominal cross-sectional areas greater than 2 A 5mm ² wire, the flame will automatically extinguish after being applied to the wire for 30 seconds. If the conductor is seen before the specified time, the flame can be removed. Record the time it takes for the wire to continue burning until self extinguishing and the remaining insulation length at the top of the sample.
