1. Smoke density box test box part:
a. The internal dimensions of the box is 3000mm X 3000mm X 3000mm, the total internal volume is 27 cubic meters;
b. The inside of the box is made of SUS 304 stainless steel and the outside is made of iron spray. Due to the burning test process, corrosive gas is continuously released. The inner wall of the box is treated with Teflon dark color, which is not only resistant to corrosive gases. Erosion, while testing, will not cause failure of test results due to reflective;
c. The test box is equipped with a laboratory door and an observation window, so that the user can observe the state in the combustion chamber;
d. On the left and right sides of the wall, a transparent glass plate is installed, and the light source and the optical receiving device can be respectively installed on both sides;
e. Open several ventilation holes near the ground to ensure the balance of atmospheric pressure inside and outside the box.
2. Smoke density test box measurement and data acquisition part:
a. Prepare a desktop fan to evenly agitate 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 test personnel;
d. In the preparation of combustion test brackets and stainless steel alcohol trays;
e. The light source is an imported light source, and the test light source is controlled by a constant current source, and has higher stability;
f. The light source is accepted as a silicon photocell, equipped with a cosine calibration device and a color filter. Through this measure, a higher human eye matching degree can be achieved;
g. Standard transmittance, using 19 cabinet floor installation, built-in touch screen computer and printer.
3. Smoke density test box optical technical parameters:
a. Using a constant current source to control the light source, the data is more stable and reliable than the constant voltage mode;
b. Can automatically obtain the optical gear position, the general accuracy is 0.01%;
c. Matching error: f1 ≤ 4%, the overall linear accuracy is 1%.
27 cubic meters wire and cable smoke density test box, developed according to IEC 61034, BS 6853, GB/T17651.1~2 test standards, mainly used for wire and cable and optical cable smoke density performance testing. During the test, when the smoke is generated, the light path is blocked by the smoke, and the optical transmittance is continuously changed, thereby obtaining the minimum transmittance value and the test time for achieving the minimum transmittance.
