Brief introduction: Plastic smoke density test method, from the national institute of standards and technology NIST (NBS), has been promoted in the field of numerous tests and application, the test method can be used to detect plastic products, the rail transit and non-metallic materials, non-metallic materials, wire and cable products ship and smoke density rank; According to the test method, the general applicable standard for ASTM E662, ISO 5659-2 and the NES 711 smoke density test method of national standard; Compared to before the test standard of building materials smoke density tester method has more accurate test results, at the same time optical sensor using more sophisticated photomultiplier tubes, can capture the casing slight variation of the flue gas; If equipped with other testing device, such as drager tube gas detection, can undertake air standard of smoke toxicity test, and Fourier transform infrared (FTIR) transform device, can complete the flue gas content of qualitative and quantitative analysis, etc. Technical parameters: 1. The smoke density test box cavity internal size respectively: 914 * 914 * 914 mm, inside and outside casing wall adopts teflon coating processing, can resist the strong corrosive gas, makes the box body can greatly extend the service life; 2. The box body adopts full open design method, the user can convenient installation, at the end of the test sample, can be more simple clean test box up and down the Windows, change in different test standard accessories, efficiency can be greatly extended; 3. In a test box module outer wall installation auxiliary heating device, according to different standards, set the casing temperature, the time of body temperature equilibrium; 4. The casing installation explosion-proof aluminum foil device, when accident, reduces the risk of testers person; System.after the open port pressure, with pressure regulation volumetric flask connection, can automatically adjust the pressure inside the box body; 6. Housing the top and the bottom of the box body, install automatic movement of the cylinder, making it easy for users to use; 7. Equipped with ASTM E662 radiation furnace equipment, can provide 25 kw/M2 thermal radiation output; 8. Equipped with ASTM standard E662 flame burner, cooperate with radiation furnace flame combustion test can be performed; 9. Provide air cooled copper plate heat meter, test can be used back cooling way to adjust the surface temperature; 10. Equipped with ISO 5659-2 / GB/T8323 radiation cone device, can provide 50 kw/M2 thermal radiation output; 11. Provide the ISO 5659-2 / GB/T8323 standard flame burner, cooperate with radiation cone can be flame burning test; 12. Provide us MEDTHERM water-cooled heat flow meter () with cone calorimeter, included can be traced back to the United States NIST measurement certificate; 13. Can be equipped with the circulating cooling water, no need of external cooling water, making it easy for users to use; 14. Equipped with weighing device for MOD smoke density test and material thermal weightlessness tests; 15. The sensor range of 0-5000 - g, 0.01 g precision; Optical cassette, 16. System.after the installation accepted as photomultiplier tube side window type, S - 4 frequency response, light transmittance accuracy can reach 0.0001%; 17. Cassette, install the wheel rotation device, according to the change of the state of smoke density, automatically switch to the Clear, Filter and Dark three gear; 18. Cassette installed in ND2 neutral filter, can facilitate users' self calibration, and can be used in testing switch gear; 19. The lower part of body for incandescent light source, can provide uniform light output;
