In accordance with GB/T 5169.10-13 (IEC 60695-2-13), test specimen dimensions: Prepare specimens in accordance with the standard; typical dimensions are 100 mm × 100 mm × thickness (based on the actual thickness of the material in use, not to exceed 13 mm).

Number of specimens: At least 3 specimens per test group, which must be prepared under the same conditions.

Conditioning: The test specimens must be left in an environment at 23±2°C and 50±5% humidity for at least 24 hours to ensure they are in a stable condition.

4.3 Internal Environment

① Pass the pull ropes of the two weights over the trolley, then hang them on the two pulleys, respectively; ② Install the specimen; if necessary, use a metal mesh specimen holder to adjust the specimen’s position, ensuring that the contact point of the glowing wire is in the center of the specimen and that the contact area meets the standard requirements;③ Place the specimen tray, the pine board, and the special test paper directly beneath the U-shaped tip of the glowing wire.

4.4 Adjusting the Position of the Proximity Switch

Adjust the position of the proximity switch according to the sample. You can first move it to the right a short distance to ensure safety. First, press the “Reset” button, then tap “Left” on the touchscreen, and the cart will automatically move to the left.

When the carriage reaches the proximity switch, it stops. If the position is not ideal, tap “Reset” on the touchscreen, and the carriage will automatically move away. Then, after readjusting the proximity switch’s position, tap “Move Left” again. Repeat this process until the cart finally stops at the desired position. The final position should be: the sample is in contact with the hot wire, and the distance between the hot wire and the sample cart is 7 mm. This distance can be measured with a gauge when the cart is at its final position, as shown in the figure below:

Note 1: Pay close attention to the position of the two weights. Throughout the entire process, the weights must not come into contact with any other objects and must remain suspended steadily in the air at all times. If this is not the case, adjust the position of the weights or the length of the pull rope.

Note 2: After adjusting the proximity switch position, tap “Reset” on the touchscreen to return the carriage to its initial position, then wait for the test to begin. Note: If you need to test samples of other shapes and sizes later, you may need to readjust the proximity switch position.

5. Operating Procedures for the Glowing Wire Test

5.1 Setările parametrilor de testare

In accordance with the requirements of the GB/T 5169.11 (IEC 60695-2-11) standard, make the following settings.

Glow time (Ta): Typically 30 seconds; Ignition time (Ti): Same as glow time, 30 seconds; Flame extinction time (Te): 60 seconds.

If users are referring to other standards or conducting non-standard tests, they may adjust the settings as needed.

5.2 Adjusting the Glow Wire Temperature

Make sure the current adjustment knob is set to the minimum position to avoid a sudden high-current surge.

Tap “Heat” on the touchscreen. ① Then slowly turn the current knob clockwise. ② The display shows the current heating current, and ③ the current temperature of the heating element. Note: Please adjust the current knob slowly and wait patiently for the heating element to stabilize at the specified temperature.

The figure below shows the relationship between current and the temperature of a glowing wire:

In practice, the current may vary slightly depending on the specific operating environment; however, this does not affect the operation of the equipment or the test results. Common test temperatures are 550°C, 650°C, 750°C, 850°C, and 960°C. Please select the appropriate temperature based on the material’s required flame resistance rating.

5.3 Testarea funcțională

Make sure the test chamber door is closed. Click “Reset (D)” to clear the historical test data. Click “Left (A)” to move the sample cart with the samples to the left.

When the sample cart reaches the proximity switch, the sample comes into contact with the incandescent wire, and the test begins. The incandescence time (Ta), ignition time (Ti), and flame extinction time (Te) are all timed simultaneously.

If the sample ignites within the 30-second heating period, immediately click “Ignition Time Pause (B)” and record the ignition time Ti. Observe the combustion: the height of the flame and whether any burning droplets ignite the test paper, and manually record the relevant observations.

After the 30-second heating period is complete, the sample carrier automatically disengages from the heating wire, and the “Heat” button automatically pops up, stopping the heating process. As soon as the sample flame goes out, immediately click “Flame Extinction Time Pause (C)” to record the flame extinction time (Te).

Note 1: If the sample does not ignite during the test, there is no need to click “Ignition Time Pause (B)” or “Extinction Time Pause (C),”

Note 2: If the flame continues to burn beyond the set value of Te (the flame extinguishing time) of 60 seconds, manual intervention is required to extinguish the fire, and this must be recorded.

Note 3: According to the standard’s explanatory notes, the sample’s flame must extinguish within 30 seconds after the sample leaves the incandescent wire for the test to be considered passed. Example: If the flame extinction time (Te) recorded during the glowing wire test is 45 seconds—meaning the sample’s flame extinguished 15 seconds after the sample left the glowing wire—this meets the standard requirements.

7.1 Calibration Preparation

7.1.1 Calibration Conditions

Environmental Requirements: Temperature 23±2°C, humidity 50±5%, no airflow disturbances.

Equipment Status: Power on the equipment and allow it to warm up for 30 minutes to ensure stable operation; the heating wire is clean and free of residue, and the thermocouple is securely connected.

Calibration tools: Standard silver foil (0.1 mm thick, purity ≥ 99.9%), stainless steel gauge.

7.1.2 Calibration Basis

In accordance with the requirements of the GB/T 5169.12 (IEC 60695-2-12) standard, the instantaneous melting of a silver foil at 960°C is used as the basis for calibration.

7.2 Procedura de calibrare

Open the test chamber door and place the silver foil flat directly above the front end of the U-shaped tip of the incandescent wire, ensuring that the silver foil makes good contact with the incandescent wire and is not suspended in the air. Then close the test chamber door.

Tap “Heat” on the touchscreen, slowly turn the current adjustment knob to gradually increase the temperature, and observe the condition of the silver foil.

When the temperature reaches 960°C, observe whether the silver foil melts instantly; if it does not melt, continue to heat it slowly and record the temperature at which the silver foil melts.

7.3 Handling Temperature Deviations During Calibration

If the temperature displayed when the silver foil melts deviates by ≤±5°C from 960°C, the calibration is considered acceptable; if the deviation exceeds ±5°C, the position of the thermocouple must be adjusted (ensuring that the thermocouple probe is in close contact with the hot wire).

Repeat the calibration procedure after making adjustments until the deviation meets the requirements; if the device still fails to meet the requirements after multiple adjustments, replace the thermocouple or the hot wire.

Note: The glow wire and thermocouple are consumable items; replace them promptly if their parameters are incorrect. Severe open flames during testing can also shorten the service life of the glow wire and thermocouple.
