Needle flame testing machine

Needle flame testing machine

Product model: F243

Compliant with standards:

Requirements of relevant standards such as GB4706.1, GB5169.5-2008, IEC60695-2-2, IEC60695-11-5, etc

Applicable scope:

The needle flame tester is suitable for the research, production, and quality inspection departments of electrical and electronic equipment and its components, such as lighting, low-voltage appliances, household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors, accessories, etc. It is also suitable for the insulation materials, engineering plastics, or other solid combustible materials industry.

Experimental principle:

The needle flame tester uses specified dimensions( Φ A needle shaped burner with a diameter of 0.9mm is ignited with a specific gas (butane) at a 45 ° angle, and the ignition hazard of small flames caused by internal fault conditions is evaluated based on whether the sample is ignited, the duration of combustion, and the length of combustion.

Product features:

1. The characteristic of this experimental equipment is that the combustion chamber and main mechanical parts are made of stainless steel, with exquisite design and resistance to smoke corrosion. The control system has a high degree of automation, with imported key components, digital display time, three-dimensional adjustable fixtures, automatic control of test programs, independent ventilation, convenient observation and recording, and stable and reliable use.

2. The outer shell and important components of the test chamber are made of stainless steel, which is resistant to smoke and gas corrosion. The control system has a high degree of automation and has an automatic ignition function. Temperature and time digital display, easy to observe and record, stable and reliable to use.

Technical parameters:

1. Needle shaped burner: stainless steel, inner hole Φ 0.5 ± 0.1mm, outer diameter ≤ Φ 0.9mm, length ≥ 35mm;

2. Burner angle: vertical (when adjusting and measuring flame height) or inclined at 45 ° (during testing);

3. Combustion gas: 95% butane gas or propane gas;

4. Igniting cushion layer: White pine wood board (10mm thick), covered with a layer of 12-30g/m2 standard silk paper on the surface, 200mm ± 5mm below the flame application point;

5. Temperature range: 0-1000 ℃;

6. Flame temperature requirement: From 100 ± 2 ℃ to 700 ℃± 3 ℃, it should be completed within 23.5 ± 1.0 seconds;

7. Flame height: 12mm ± 1mm, height measurement device;

8. Burning time: adjustable from 0s to 999.9s, generally set to 30s;

9. Holding time: 0s~999.9s, automatically recorded, manually paused;

10. Test space: ≥ 0.5m3, with a black background (0.75 m3 or 1 m3 can be customized according to customer requirements);

11. Temperature sensor: K-type insulated armored thermocouple( Φ 0.5mm);

12. During the experiment, the program is automatically controlled with an independent exhaust system;

13. Boundary dimensions: L1120 * W520 * H1250mm, exhaust Φ 100mm;

14. Test power supply: 220V/AC, 50Hz.
