Introduction: The GB/T8323 standard specifies sheet materials, composite materials or specimens of a thickness not exceeding 25 mm, placed vertically in a cabinet with a specified level of heat radiation source, with or without a pilot flame. , measuring the method of generating smoke from the exposed surface, this test method is applicable to all plastics, and can also be applied to the evaluation of other materials (such as rubber, textile coverings, painted surfaces, wood and other materials), suitable for the plastics industry, It is widely used in production plants and research and test units in the solid materials industry. Compliance with standards: ISO5659-2 ASTM E662 BS 6401 GB/T 8323 Technical Parameters: 1. Model: 5920 2. Test chamber internal dimensions: 914 × 914 × 610 mm 3. The inner and outer walls of the box are treated with Teflon coating, which can resist the erosion of strong corrosive gas, so that the service life of the box can be greatly extended; 4. The cabinet adopts the design method of fully open door 5. Install an auxiliary heating device on the outer wall of the test box, which can set the temperature inside the box according to different standard requirements, and shorten the temperature balance time of the box; 6. Install an explosion-proof aluminum foil device inside the box to reduce the personal risk of the tester when an accident occurs; 7. The top of the box has a pressure relief port, which is connected with the pressure regulating volume bottle to automatically adjust the pressure inside the box; 8. The top of the box and the bottom of the box are equipped with cylinders that can move automatically, which is convenient for users to use; 9. Equipped with ASTM E662 radiant furnace unit to provide 25KW/M2 heat radiation output; 10. Equipped with ASTM E662 standard open flame burner, combined with radiant furnace for open flame burning test; 11. Provide an air-cooled copper plate calorimeter, which can be adjusted by using the back cooling method during the test; 12. Equipped with ISO 5659-2/GB/T8323 radiation cone device, which can provide 50KW/M2 heat radiation output; 13. Provide ISO 5659-2/GB/T8323 standard open flame burner, with the radiation cone for open flame burning test; 14. Provide US MEDTHERM water-cooled heat flow meter (with cone calorimeter), which can be traced back to the US NIST measurement certificate; 15. It can be equipped with self-circulating cooling water source, no need for external cooling water source, which is convenient for users to use; 16. Equipped with weighing device for MOD smoke density test and thermal weight loss test of materials; 17. The sensor range is 0-5000g with an accuracy of 0.01g; 18. Equipped with NES 711 open flame burner and mixing fan; 19. The switching between the radiant furnace and the radiation cone is connected by an aviation joint, and the user can replace the standard test device by simply plugging and unplugging; 20. The optical cassette is installed on the top of the box, and the light source is accepted as a side window type photomultiplier tube. The S-4 frequency response can achieve a transmittance accuracy of 0.0001%. 21. In the cassette, the wheel rotation device is installed, and can automatically switch to the Clear, Filter and Dark positions according to the change of the smoke density state; 22. The ND2 neutral filter is installed in the cassette, which is convenient for the user to self-calibrate, and can automatically switch the gear position during the test; 23. The lower part of the box is an incandescent light source, which can provide uniform spot output;
