Horizontal Burning Smoke Density Tester L3000 * W3000 * H3000 Mm IEC 61034 GB/T 17651

IEC 61034 GB/T 17651 Cable and Wire Horizontal Burning Smoke Density Tester

Application:

Cable Burning Smoke Density Tester, to determine the smoke density of cables burning under defined conditions. This smoke density tester is used for horizontal burning of a cable or fiber optic cable, the smoke that is released from the flame combustion or no flame combustion condition, the light transmission rate of smoke can be used to compare different cable or judgment is in accordance with the specific requirements of the means

Standards:

IEC 61034-1, IEC 61034-2, BS 6853, GB/T 17651.1, GB/T 17651.2

1.3 Structure: the front with a glass observation window, on both sides of the wall relative to each set a transparent sealing window, size: 100mmx100mm, so that the level of light measurement device through the beam, the center of the sealed window from the ground height of 2150mm. The bottom of the open a number of ventilation holes, ventilation holes for the 100x500mm (50 square centimeters)

1.4 The bottom has six wheels and six casters

1.5 The roof is equipped with an exhaust fan.

2. Optical measurement system:

2.1 Light source: imported quartz halogen lamp, nominal power: 100W Nominal voltage: 12V Nominal optical return: 2000 ~ 3000Lm

2.2 Receiver: The spectral response matches the International Commission on Illumination (CIE) photometer.

2.3 Installation: Installed in the length of 150 tubes at one end, the other end of the dust-proof window, the pipe wall is glossy black, anti-reflection.

2.4 Light transmittance 0% is no light through, 100% light transmission without blocking completely through.

3. Standard Fire Source:

3.1 1.0L alcohol source of alcohol: 90% ethanol, methanol 4%, water 6%

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

3.3 Installation location: alcohol plate set up from the ground with a height of 100mm, so that air circulation.

4. Smoke Blending:

The use of desktop fans to smoke in the combustion chamber evenly distributed. Fan shaft distance from the ground height of 250mm, with a wall 500mm, 7 cubic meters per minute air volume. During the test the air was blown horizontally by the fan.

5. Blank test:

The purpose is to adjust the combustion chamber to achieve the required temperature, burning alcohol lamp to the combustion chamber temperature: 25 ± 5 ℃.

6. Temperature measuring device:

In the door from the ground surface height 1.5M, 0.5M away from the wall with a temperature sensor. Monitor the laboratory temperature.

7. Random accessories:

7.1 Contains a set of transmittance measurement software, can output curves and reports.
