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:
| Control box size | 600mm(W)×600mm(D)×1600mm(H) |
| power supply | AC 220V,50/60Hz, 1A |
| Combustion box | 3m×3m×3m(provided by the customer) |
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%.
