4.1 Environmental and Equipment Inspection

4.1.1 Persyaratan Lingkungan Pengujian

Set the ambient temperature to 23±2°C and the relative humidity to 50±5% to prevent environmental factors from affecting the test results. Note: The temperature and humidity requirements for the equipment’s storage environment differ from those for its operating environment.

4.1.2 Equipment Piping Connections and Inspections

Verify that the exhaust pipe is securely connected to the equipment’s exhaust outlet and extends to the outside.

After connecting the propane cylinder to the equipment, set the cylinder pressure regulator to slightly above 0.1 MPa. Connect the air compressor, which delivers compressed air at a pressure between 0.5 and 1 MPa, to the equipment.

Check that the propane gas lines and compressed air lines are properly connected and free of leaks, and that the clamps are securely fastened. Apply soapy water to the joints and observe for bubbles to determine if there are any leaks.

4.2 Adjusting the Flame

Adjust the Ben Sheng lamp to a vertical angle.

On the touchscreen program interface, press the “Propane Gas On” button, roughly adjust the propane pressure knob and the flow meter knob, then press and hold the “Ignition” button to successfully ignite the flame. Then adjust the propane settings to the specified standard values (propane pressure: 0.1 MPa; flow rate: 650 ± 30 mL/min). Important Note: Minimize the time between pressing the “Propane On” button and ignition (less than 5 seconds) to prevent excessive propane buildup in the combustion chamber, which could pose a hazard.

Press the “Air On” button, then adjust the air pressure control knob and the flow meter knob to the specified standard values (air pressure: 0.1 MPa; air flow rate: 10 ± 0.5 L/min).

Use a gauge to measure the flame height, and fine-tune the air and propane gas flow rates separately until the flame meets the test requirements. The flame heights required by the IEC 60695-11-2 (GB/T 5169.14) standard are as follows:

Gambar 8

The gauge is used as follows; all dimensions marked on it conform to the standard:

Gambar 9

Once the flame is adjusted, press the “Propane On” button to make it pop out, which will shut off the propane gas supply and cause the flame to go out automatically. Press the “Air On” button again to shut off the compressed air supply.

No changes are needed at this time to the propane cylinders, air compressors, or any of the adjustment knobs on the front panel of the RSB-WC equipment, to facilitate direct combustion testing or temperature calibration operations later on.

4.3 Sample Pretreatment and Mounting

4.3.1 Perlakuan Awal Sampel

Sample Preparation: Cut a sufficiently long wire or cable sample in accordance with the standard, and remove any surface oil or impurities. Requirements for sample length in the IEC 60695-11-2 (GB/T 5169.14) standard: The test specimen shall be a single length of wire or cable measuring (600 ± 25) mm.

Conditioning: Allow the sample to stand in the test environment (23±2°C, 50±5% humidity) for at least 24 hours.

4.3.2 Sample Mounting and Bunsen Burner Adjustment

Secure the pretreated sample to the sample holder, ensuring that the sample is vertical and does not wobble;

Round cable: The distance between the flame contact point and the lower edge of the horizontal bracket is 475 ± 5 mm;

Flat cable: The flame contact point is located in the center of the flat section, 475 ± 5 mm from the lower edge of the upper support;

Adjust the angle of the Bunsen burner to 45°, and use a gauge to verify its position so that the tip of the blue inner cone of the flame just touches the surface of the specimen, as shown in the standard diagram below:

Gambar 11

Place the collection tray directly beneath the sample to collect the combustion droplets.

5. Cable Combustion Test Procedure

5.1 Menetapkan Parameter Uji

Burn Time Setting: Set the burn time based on the equivalent diameter of the sample cable:

Gambar 12

Equivalent Diameter Conversion: For non-circular cables (such as flat cables), measure the circumference and convert it to an equivalent diameter (calculated as if it were a circular cable).

Afterglow Time Setting: The standard does not specify a value for afterglow time. If you are conducting tests according to other standards and need to use the afterglow time to calculate the burn rate, please set a reasonable afterglow time.

5.2 Prosedur Uji

First, rotate the base of the Bansheng lamp to a different angle;

Tap “Propane On,” press and hold the “Ignition” button to light the flame, then tap “Air On”;

Once the flame has stabilized, rotate the Bunsen burner toward the cable to conduct the combustion test. At the same time, tap “Start Test” on the touchscreen; the combustion timer will begin counting down, and the device will automatically maintain the flame;

During the test, monitor the combustion status of the sample through the observation window and record whether the fire spreads and whether there are any droplets, etc.;

Once the burn time has elapsed, the device automatically shuts off the propane and air supply, the flame goes out, and the “afterglow time” begins;

When the sample’s afterglow has completely extinguished, immediately click “Afterglow Pause” and record the afterglow duration.

7. Kalibrasi Suhu

7.1 Calibration Preparation

7.1.1 Calibration Conditions

Ambient temperature: 23 ± 2 °C; relative humidity: 50 ± 5%; no airflow disturbances;

The calibration copper block and thermocouple are in good condition; the copper block is made of Cu-ETP UNS C11000.

7.1.2 Calibration Basis

Requirements regarding the temperature rise time in the IEC 60695-11-2 (GB/T 5169.14) standard: The time required for a copper block to heat up from 100 °C ± 5 °C to 700 °C ± 3 °C shall be 46 s ± 6 s.

Prosedur 7.2

Adjust the flame according to the procedure in Section 4.2, then extinguish the flame.

Insert the thermocouple plug into the Omega Type K thermocouple socket provided in the test chamber, and secure it using the standard copper block 95 mm directly above the burner tip, ensuring that the flame fully contacts the copper block.

Gambar 14

Gambar 15

Close the test chamber door, enter the temperature calibration interface, and set the following: start temperature for the timer to 100°C, end temperature for the timer to 700°C, and leave the temperature correction at the default value. Click “Reset” to clear the historical data.

Return to the operating screen, tap “Turn on Air” and “Turn on Propane,” then press and hold “Ignition.”

Gambar 16

Return to the temperature calibration screen and observe the current temperature and heating time displayed on the touchscreen. The timer starts automatically when the copper block reaches 100°C and stops automatically when it reaches 700°C.

Repeat the calibration three times, allowing the copper block to cool naturally to below 50°C after each measurement.

Calculate the average time for the temperature rise based on the three measurements; if it falls within 46 s ± 6 s, the flame meets the requirements. A single temperature calibration is sufficient for each tank of propane gas.

7.3 Handling Calibration Temperature Deviations

The temperature rise time is used to determine whether the propane gas you are using, the flame being calibrated, and the test conditions meet the standard test requirements. If the temperature rise time is incorrect, it means your test does not meet the standard requirements; it does not indicate a problem with the equipment itself.
