Building Materials Smoke Density Tester for Assessment of Density of Smoke
Product Introduction
ASTM D2842 Specifies the apparatus and methods of test for the assessment of density of smoke from the burning or decomposition of plastics. Smoke density tester can measure the smoke density of burning or decomposition of plastics.
Technical parameters
1. The combustion chamber is made from stainless steel with Teflon
coating, to maximize operating life.
2. Provided with two burners to ignite the sample and drip.
3. Smoke Obscuration - measured with an Incandescent lamp system,
using photodiodes.
4. Provided with software to judge the testing results.
5. Records ignition and extinguishment time of flames. And the
other test results are light transmission (%), Maximum smoke
density (MSD) and Smoke density grade (SDR) and so on.
Product Features
1. The test chamber is made of Teflon as a coating to resist the
smoke from the combustion and greatly extend the life of the
product.
2. The red letter "EXIT" font on the bottom of the box is
installed, and the tester can discriminate the clear and fuzzy
state of the sample through the transparent observation window;
3. The test light source is an incandescent lamp, 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 light and infrared light that are not recognized by
the human eye, and has excellent human eye matching degree. ;
4. The main burner is subjected to flame shock at a pressure of 276
KPA, and an auxiliary burner is provided to perform flame impact on
the dripping object;
5. The auxiliary burner gas pressure is 138 KPA, and the molten
dripping is further burned;
6. The standard test software can not only display the
transmittance value per 15s optical path, but also draw the
transmittance test curve. After the test is finished, 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 sets of
test samples can be synthesized to draw a SDR smoke density
development curve;
8. The computer software can be used to compare the three sets of
test results SDR at the same time, and automatically determine
whether the test results can be met;
9. Data can be output from the computer, and print and printable
test reports can be connected for user convenience.
Product Details
The Smoke Density Tester was developed by Rohm and Haas Company of the United States for internal control. It was developed in the 1970s in the last century according to the American ASTM D2843 standard. The theoretical basis is the use of Bill's law, ie The sample is directly impacted by the flame, and after the material is burned to generate flue gas, the gas density value (SDR) is discriminated by blocking the transmittance of the light. At present, more applications have been applied in GB 8624, for the detection of smoke density of PVC casing, and also for the detection of smoke density performance of automotive interior materials.
