ASTM D2843 Building Materials Smoke Density Test Apparatus Laboratory Testing

ASTM D2843 Building Materials Smoke Density Analysis Instruments Laboratory Testing

ASTM D 2843 Smoke Density Tester Product Introduction:

In a fire accident, thick smoke is often the main factor that hinders people's escape and rescue. Therefore, accurately evaluating the smoke density of building materials is crucial for fire prevention and safe evacuation.

The building material smoke density tester strictly complies with the technical specifications of the national standard GB/T8627-2007 and is suitable for measuring the thermal decomposition or combustion characteristics of materials, products and components in a controlled laboratory environment. The instrument quantifies the static smoke production of materials under heat or open flames, scientifically evaluates their smoke performance, and provides key data support for the development of fireproof materials, building safety design and fire protection standards, thereby effectively improving the fire safety level of buildings.

ASTM D 2843 Smoke Density Tester Technical Specification

ASTM D 2843 Smoke Density Tester Features:

1. The test box uses Teflon as a coating, which can resist the erosion of smoke generated by combustion and greatly extend the life of the product;
2. The bottom of the box is installed with a white background and red "EXIT" font. The tester can judge the clarity and blurriness of the sample through the transparent observation window;
3. The test light source is an incandescent lamp, and the photoelectric sensor is a silicon photodiode. The silicon photodiode has a cosine calibration function and is equipped with a color filter to filter out ultraviolet and infrared light that cannot be recognized by the human eye. It has excellent human eye matching;
4. The main burner is at a pressure of 276KPA, and the test sample is subjected to flame impact. An auxiliary burner is equipped to perform flame impact on the dripping material;
5. The auxiliary burner gas pressure is 138KPA, and the molten dripping material is further burned. Burn;
6. The standard test software can not only display the transmittance value of the optical path every 15s, but also draw the transmittance test curve. After the test, the software can display the SDR smoke density value, that is, the smoke integral value;
7. Through the test software, the test reports of the three groups of test samples can be synthesized to draw an SDR smoke density development curve;
8. Computer software can be used to compare the three groups of test results SDR at the same time to automatically determine whether they can meet the test result requirements;
9. Data can be output through the computer, connected to print and print test reports, which is convenient for users to use

Since 2008, GOLD has developed 70 kinds of fire testing instruments and served many industries such as building materials, aviation, rails, IMO, wire & cable, safety protection, and so on.
