Overview:

The flame retardant testing machine for plastic runway layer materials (oxygen index measurement method) is a professional equipment used to test the flame retardant performance of runway materials. Its core principle is to determine the required amount of material to maintain combustion in a mixture of oxygen and nitrogen gasesZUILow oxygen concentration (oxygen index, OI), the higher the OI value, the stronger the flame retardancy of the material.

This device has passed throughJINGAccurately control the oxygen/nitrogen mixture ratio, simulate the material combustion environment, measure its oxygen index, and thus determine its flame retardant level. Its testing method (such as vertical combustion method) and result judgment are in line with the requirements of GB 14833-2020 standard for the flame retardant performance of synthetic material runway surface layer, and are key testing tools to ensure the safety of runway materials.

Experimental Procedure:

1. Place the pine board in the middle of the test chamber, and place the pattern on the pine board. The middle of the pattern should prevent the fiber layer discs with a diameter of 25mm and a total weight of 0.8g from being stacked；

2. Soak the fiber layer disc evenly in 2.5ml of 96% alcohol, then ignite and let it burn naturally；

3. After the combustion flame and afterglow are extinguished, measuretryThe diameter and size of the combustion patches left on the surface of the pattern are accurate to 1mm；

4. During combustion, if the fiber layer disc flips or falls off，The style should be replaced and retested.

5. Evaluation of experimental results

The diameter of the combustion plaques left by the 5 styles is ≤ 50mm, and this sample can be determined as Class I flame retardant.
