IEC 61034 3 Meter Cube Wire And Cable Smoke Density Tester Smoke Transmittance Test Device

Wire And Cable Smoke Density Tester Product Introduction:

The 3m cubic wire and cable smoke density test box is developed according to the IEC 61034, BS 6853, GB/T17651.1~2 test standards, and is mainly used for smoke density performance testing of wires, cables and optical cables. During the test, when smoke is generated, the light path is blocked by smoke, and the optical transmittance is continuously changed, thereby obtaining the minimum transmittance value and the test time to reach the minimum transmittance.

Wire And Cable Smoke Density Tester Standards:

• GB/T17651.1～2
• IEC61034

Wire And Cable Smoke Density Tester Technical Specification:

Wire And Cable Smoke Density Tester Features:

1. Smoke density box test box:
a. The internal dimensions of the box are 3000mm X 3000mm X 3000mm, and the total internal volume is 27 cubic meters;
b. The interior of the box is made of SUS 304 stainless steel and the exterior is iron spray-coated. Since the combustion test process will continuously release corrosive gases, the inner wall of the box is treated with dark Teflon, which can not only resist the erosion of corrosive gases, but also will not cause the failure of the test results due to reflection during the test;
c. The test box is equipped with a laboratory door and an observation window, so that users can observe the state in the combustion chamber;
d. Transparent glass plates are installed on the left and right walls, and light sources and optical receiving devices can be installed on both sides;
e. Several ventilation holes are opened on the part of the box close to the ground to ensure the balance of atmospheric pressure inside and outside the box

2. Smoke density test box measurement and data collection part:
a. Prepare a desktop fan to evenly stir the smoke in the combustion chamber;
b. The top of the box is equipped with a centrifugal fan to remove the smoke generated by the test;
c. Surface ignition device, remote ignition to ensure the safety of testers;
d. Prepare combustion test bracket and stainless steel alcohol tray;
e. The light source is an imported light source. The test light source adopts constant current source control and has higher stability;
f. The light source accepts silicon photocells, equipped with cosine calibration devices and color filters. Through this measure, it can have a higher human eye matching degree;
g. Standard transmittance, using 19 cabinet floor installation method, built-in touch screen computer and printer.

3. Optical technical parameters of smoke density test box:
a. Constant current source is used to control the light source. Compared with constant voltage mode, the data is more stable and reliable;
b. The optical gear position can be automatically obtained, and the general accuracy is 0.01%;
c. Matching error: f1≤4%, the overall linear accuracy is 1%.
