Testech shaft space cable combustion test equipment combined with test box, burners, smoke pipe, control cabinets, gas control system, exhaust control system, temperature acquisition system and data acquisition and processing systems and user operating systems; the test system is used in the installation of poles or vertically through the height of the ground floor of the wires and optical fibres of the flame height value and thus test the cable combustion level; the purpose of this test is to detect The purpose of the test is to determine whether the flame combustion characteristics of the uplift wires comply with the requirements of the National Electrical Code. The test is not intended to detect toxicity or corrosiveness by combustion or decomposition.
Model: FTech-UL 1666 
Testing Standards
UL1666, ANSI/ASTM D 5207 & UL 1581, ANSI/ASTM D 5025
UL1666<<Test for flame propagation height of electrical and optical-fiber cables installed vertically in shafts>>
Parameters
1. U-type pressure gauge: measuring chamber pressure maintained at 0-12PA;
2. Hygrometer: measuring chamber temperature and humidity;
3. The structure of the chamber: the overall structure of the concrete wall by the brick, the first layer is 1.22M, the second layer is 3.66M, the top is 2.24M. External dimensions: 7.12M high x1.3M wide x2.5M long;
4. The wall structure is a density of 106lb / ft3 (1698kd / m3) of concrete, the thermal conductivity (k) at 21.1 ºC for the 0.38Btu (0.055W / m);
5. The first and second layer by the 203mm thick ordinary weight of the cement composition.Roof is made of wall to ensure its tightness;
6. The measuring hole in the second layer must be above the vertical hole of the first layer measuring hole (305mm by 610mm), each hole is 203mm behind the box and 102mm from the side of the box
