Features

1. It adopts an embedded processor and Windows CE operating system.

2. With an 8 - inch liquid - crystal touch screen, it can display the test status in real - time.

3. It integrates two functions, "sieving experiment" and "combustion rate experiment", into one.

4. It is applicable to the detection of two types of sample materials: non - metallic powder and metallic powder.

5. It is equipped with a standard stacking mold and features a user - friendly shaking handle design.

6. Strictly in accordance with standard requirements, an ignition torch is used for the sieving experiment, eliminating the need for a gas cylinder and ensuring safety.

7. A nitrogen rod is used as the ignition source for the combustion rate experiment. The material has high stability, and the ignition source temperature detection device ensures that the ignition temperature reaches above 1000°C.

8. It uses full - automatic infrared flame detection technology, which can reliably detect open flames and smoldering phenomena, ensuring detection accuracy.

9. It has a fault - detection function and audible and visual alarm functions to ensure the safety of the experiment.

10. The experimental process is fully automated, requiring no manual intervention. It supports functions such as parameter setting, data storage, and report viewing.

Automated Unit

Experimental Parameter Storage/Report Generation Module: Supports data export and report viewing.

2. Auxiliary Accessories

Sample Processing: Standard sieves (to match experimental particle size requirements), sample drying oven (to control sample moisture content), quantitative sample spoon;

Calibration and Maintenance: Standard combustion rate sample (for instrument calibration), cleaning brush/cotton swabs (to clean mold/cavity residue);

Operating Tools: High-temperature resistant protective gloves, data export USB flash drive (for storing test reports).

Test Procedures

1. Sample Preparation

Dry the solid material to be tested (non-metallic/metallic powder) to ensure the moisture content meets the corresponding standard (e.g., GB/T 21618-2008 requirements); If it is a block material, grind it into powder and then pass it through a standard sieve to ensure uniform particle size.

2. Instrument Preparation

Start the instrument and access the Windows CE system via the 8-inch touchscreen. The instrument will automatically complete a self-check;

Select the modules according to the testing requirements:

Sieving Experiment: Install the standard stacking mold;

Combustion Rate Experiment: Adjust the nitriding rod ignition source (ensure the temperature ≥1000℃);

Calibrate the instrument using a standard combustion rate sample to verify the accuracy of infrared flame detection.

3. Sieving Experiment Operation (corresponding to UN Test N.1)

Load the quantitatively processed sample into the standard stacking mold and use the vibrating handle to sieve and disperse the sample;

Set the experimental parameters on the touchscreen and start the gas-free ignition gun for ignition;

The infrared detection device monitors in real time and records whether the sample continues to burn.

4. Combustion Rate Experiment Procedure (corresponding to GB/T 21618-2008)

Evenly spread the powder sample to be tested into the combustion chamber;

Set the ignition source parameters for the nitriding rod and start the fully automatic experimental procedure;

The instrument automatically completes ignition and combustion process monitoring, recording data such as combustion time and flame propagation speed;

The system automatically calculates and outputs the combustion rate of the sample.

5. Data Processing and Conclusion

After the experiment, view/export the test report via the touchscreen (data storage supported);

After the instrument cools down, clean the mold and chamber of any sample residue using cleaning tools;

Turn off the power to complete the experiment.
