Product Introduction

The RT-746 thermal radiation flame propagation tester can evaluate the performance of rigid and elastic materials with a thickness exceeding 5mm. It is developed according to the French standard NFP92-501 for fire resistance testing of building materials and railway vehicles. The principle of the test is to apply 30KW/m2 thermal radiation to the sample, which may cause the sample to emit flammable gases and trigger the combustion of volatile gases. At the same time, the flame propagation state is observed, and data that can be used to estimate the heat release is collected through the combustion of the material. Applicable to the radiation test method for fire resistance performance of materials used in railway vehicles.

How to use the thermal radiation flame propagation tester to provide detection solutions?

To better utilize the thermal radiation flame propagation tester to provide detection solutions, we must comprehensively consider the actual application scenarios and specific needs. Here are some suggestions from DGRIGHT:

1. Select the appropriate model and specifications of the thermal radiation flame propagation tester according to the application scenario. Different instrument models have different measurement ranges and accuracies, which need to be selected according to actual needs. At the same time, factors such as the instrument’s installation and maintenance costs and ease of operation also need to be considered.

2. Before using the thermal radiation flame propagation tester, the equipment needs to be calibrated to ensure the accuracy and reliability of the measurement results. At the same time, the equipment needs to be inspected and maintained regularly to ensure its normal operation and service life.

3. When conducting flame propagation tests, appropriate experimental conditions and parameters need to be set, such as fuel type, temperature, pressure, and oxygen concentration. These parameters have a significant impact on measurements such as flame propagation velocity and spectrum, and require accurate control and adjustment.

4. When processing and analyzing the measurement results of the thermal radiation flame propagation tester, data analysis and processing are required to extract useful information and parameters. This requires filtering, denoising and fitting of the measurement data to obtain accurate measurement results and reliable conclusions.

5. In order to improve the safety and reliability of industrial production and scientific research, it is necessary to combine the detection results of the thermal radiation flame propagation tester and other relevant data for analysis and evaluation. This requires establishing a complete detection system and safety assurance mechanism to promptly discover and deal with potential safety hazards and problems.
