Audited Supplier IEC 61034 Smoke Density Tester for Cable China Manufacturer
Introduction:
27 cubic meter wire and cable smoke density test box, according to IEC 61034, BS 6853, GB/T17651.1~2 test standards, mainly used in wire and cable and optical cable smoke density performance test. During the test, when the smoke is generated, the optical transmittance is constantly changed through the smoke-blocking optical path, and then the minimum transmittance value and the test time to reach the minimum transmittance are obtained.
Standard:
| IEC 61034 - 1 & 2 | Measurement of smoke density of cables burning under a defined condition |
| - part 1 | Test apparatus |
| - part 2 | Test procedure and requirements |
| BS 6853 |
Code of practice for fire precautions in the design and construction of passenger-carrying trains |
Feature:
1. Test box of smoke density box:
a. The internal dimension of the box is 3000mm X 3000mm X 3000mm, and the total internal volume is 27 cubic meters;
b. SUS 304 stainless steel is used inside the box, and the outside is treated with iron plastic spray. Due to the continuous release of corrosive gases during the combustion test, the inner wall of the box is treated with a Teflon dark color, which can not only resist the corrosion of corrosive gases but also avoid the failure of test results due to the reflection of light during the test.
c, the test box is equipped with a laboratory door and an observation window, so that the user can observe the state of 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 respectively;
e. Open several ventilation holes near the ground of the box to ensure the balance of atmospheric pressure inside and outside the box
2. Smoke density test box measurement and data acquisition:
a. Prepare bench fan to evenly stir the smoke in the combustion chamber;
B. The top of the box is equipped with a centrifugal fan to eliminate 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 imported light source, the test light source, using constant current source control, has higher stability;
f, the light source is accepted as a silicon photocell, equipped with a cosine calibration device and color filter, through this measure, can have a higher degree of human eye matching;
g, standard transmittance, 19 cabinets installed on the ground, built-in touch screen computer, and printer.
3. Optical technical parameters of smoke density test box:
A. Constant current source is adopted to control the light source. Compared with the constant voltage mode, the data is more stable and reliable;
b, can automatically obtain the optical gear, the general accuracy is 0.01%;
c, matching error: f1≤ 4%, the overall linear accuracy is 1%.
