GB/T 8627-2007 Building Materials Smoke Density Tester Smoke Density Flammability Performance Test Instrument

JYMD Building Materials Smoke Density Tester

Product Description:

Developed based on the technical conditions specified in the national standard GB/T 8627—2007″Standard Test Method for Density of Smoke from the Burning or Decomposition of Plastics”. Compared to the original instruments using single-chip microcomputer technology, this product has the following features:

1. Dual control modes: can be operated via the touch screen or computer, with easy switching between the two. !One device can be operated by several computers simultaneously, allowing multiple online connections and local area network (LAN) sharing..
2. The main and auxiliary burners rotate automatically with accurate positioning.

Reasonable structural design, convenient operation and maintenance, suitable for determining the static smoke production of building materials and their products, as well as solid materials.

Applicable Standards

Designed according to GB/T 8627-2007″Standard Test Method for Density of Smoke from the Burning or Decomposition of Plastics”. Its test principle, procedures, and specimen preparation are all derived from this standard. Detailed reading of GB/T 8627-2007 before testing will provide comprehensive guidance.GB/T 8627-2007 will be very helpful.

Technical Parameters

1. Maximum Smoke Density (MSD) and Smoke Density Rating (SDR) of the specimen: MSD) and SDR: 0-100% continuously measurable, automatic calculation;
2. Bunsen burner applies flame to the specimen for 4 min;
3. Burner: Bunsen burner, length 260 mm, nozzle diameter 13 mm, at a 45°angle to the smoke box;
4. Photoelectric system: light source is a bulb, working voltage 12V;
5. Exhaust system: equipped with a powerful exhaust fan to discharge waste gas from the combustion chamber after testing;
6. Smoke density measurement range: 0 to 100%;
7. Smoke density measurement accuracy: ±3%;
8. Receiver: Silicon photocell; light transmittance 0%means no light passing through, and 100% means light passes through completely without obstruction;
9. Main burner working pressure: 276 kPa(adjustable);
10. Automatic timing, ignition, and smoke exhaust;
11. Touch display screen:
12. Size: 5-inch effective display size, length 11 cm, width 28 cm;
13. Resolution: 800 * 480
14. Communication interface: RS232, 3V CMOSor TTL, serial port mode
15. Storage capacity: 1 GB
16. Pure hardware FPGAdriven display, “zero” startup time, ready to run upon power-on
17. Uses M3+FPGAarchitecture, M3 is responsible for instruction parsing, FPGA focuses on TFT display; speed and reliability lead similar solutions
18. Main controllers all use low-energy processors and automatically enter energy-saving mode
19. Length * width  *  Height: 740 * 500 * Height 900 (mm);
20. Working Conditions
21. Ambient temperature: 0℃-40℃;
22. Relative humidity: ≤ 85%;
23. Power supply voltage and power: 220V ± 10%, 50 Hz, 100 W;
24. Combustible gas: Propane with a purity of not less than 85%or gas of equivalent purity (provided by the customer);
25. Gas pressure: 0-0.3 MPa(adjustable);
26. Environment and test requirements: Avoid direct strong light or reflection onto the instrument during operation; after the test has been running for 90 min, turn off the gas source and let the instrument cool for 15 min;
27. Ambient airflow: No forced airflow during operation;
28. The instrument should be placed in a fume hood for testing;
