3. Main features:

3.1 This testing machine is designed according to Part 1 (Test Apparatus) and Part 2 (Test Procedures and Requirements) in GB/T17651.1~2-1998 standard, the smoke density light of the cable or optical cable burning under specific conditions The measurement system consists of a light source, a silicon photocell receiver and a computer system. The light generated by the light source passes through the smoke density laboratory of 3m×3m×3m, and forms a uniform beam with a diameter of 1.5m±0.1m on the wall opposite the light source. The photocell installed at the center of the beam detects the beam intensity from the light source. When a large amount of smoke is generated in the combustion chamber due to burning cables or optical cables, the smoke absorbs a part of the photoelectricity, and the intensity of the beam reaching the silicon photovoltaic cell is weakened. The transmittance of the linear response It.

3.2 This instrument involves professional knowledge in mechanics, optics and electronics. It is a mechatronics product with the advantages of reasonable structure, stable performance and easy operation. It has a WINDOWS XP operation interface, LabVIEW style, and a perfect security mechanism. During the test, the measurement results are displayed in real time and the perfect curve is dynamically drawn. The data can be permanently saved, recalled and printed out, and the report can be printed directly.

4. The Combustion Chamber:

4.1 Use SUS304 stainless steel with a thickness of 1.5mm to be fixed on the square pass bracket to form the entire cubic combustion chamber.

4.2 Internal dimensions: L3000*W3000*H3000(mm)

4.3 Structure: There is a glass observation window on the front, and a transparent sealing window on the opposite wall on both sides, the size is: 100mmx100mm, let the light beam of the horizontal photometric device pass through, and the height of the center of the sealing window from the ground is 2150mm. There are several ventilation holes at the bottom, the ventilation holes are 100x500mm (50 square centimeters)

4.4 The top is equipped with an exhaust fan.

5. Optical Measurement System:

5.1 Light source: imported quartz halogen lamp, nominal power: 100W; Nominal voltage: 12V Accuracy: ±0.01V; Nominal luminous flux: 2000～3000Lm, Nominal color temperature: 2800K～3200K, meet the requirements of GB/T17651.1 5.2, Provide 15 spare light sources.

5.2 Receiver: It is a silicon photovoltaic cell, the signal is amplified by the board card, and input to the computer through the I/O board card, which meets the requirements of GB/T17651.1, and the spectral response matches the light meter of the International Commissioner of Illumination (CIE).

5.3 Installation: Install at one end of a pipe with a length of 150, and the other end is a dust-proof window. The inner wall of the pipe is glossy black and anti-reflection.

5.3 Light transmittance of 0% means that no light passes through, and light transmittance of 100% is completely unobstructed.

5.4 Measurable transmittance range (0～100)%;

6. Standard fire source:

6.1 The fire source is 1.0L alcohol configuration: 90% ethanol, 4% methanol, 6% water

6.2 Alcohol plate (burning boat): stainless steel thickness 1.0mm, bottom surface: 210x110mm, top surface: 240x140mm, height 80mm;

6.3 Installation position: The distance between the alcohol tray and the ground is 100mm, so that the air can circulate.

7.The Mixture Of Smoke:

Use a table fan to distribute the smoke evenly in the combustion chamber. The height of the fan shaft is 250mm from the ground, the wall is 500mm, and the air volume is 7 cubic meters per minute. Air is blown horizontally by a fan during the test.

8.Blank Test:

The purpose is to adjust the temperature in the combustion chamber to reach the specified temperature, and burn the alcohol lamp to make the temperature of the combustion chamber reach: 25±5℃.

9. Temperature Measuring Device:

A temperature sensor is installed on the inner surface of the door at a height of 1.5M from the ground and 0.5M from the wall. Monitor the temperature of the laboratory.

10. Comply with the approved combustion test in Section 10 of GB/T17651.1-1999.

11. Control part:

11.1 High-precision boards are used, and all high-quality components are used to ensure high-quality, high-speed operation of the system and advanced nature.
