ST-7601S Cable Vertical-Tray Flaming Test Room as UL1685 & UL2556

ST-7601S UL Cable Vertical-Tray Flaming Test Room（UL1685）

Standards: According to the clause 9.6 & 9.7 of UL1685-2007, UL2556-2007

Scope: Apply to check the vertical-tray fire test for determining values of cable flame propagation and smoke release when the cables are subjected to a flaming ignition source. (It is nothing to the purpose of cables, such as the electric power, telecommunications etc.)

Main components: Main consist of Ignition source & supply fire control system, collection hood & exhaust duct flux control system, pressure measurement instrumentation of gas, smoke measurement instruments & temperature measurement system, flame height measurement system etc.

Main parameter:

1.    Test room: Fire resistance bricks for walls and which density is 1698kg/m³, Interface spray black paint, and the outer size of the room is W2438×D2438×H3353mm；

2.    Door: Stainless steel frame and wired-glass door, the overall size is W0.9× H2.0m;

3.    Smoke collection hood: Which made by stainless steel, each side is to be sloped 40⁰, the hood as a cube and each side length is 914mm, there is a dust mesh under the hood and each side length is 610mm;

4.    Observation window: Which as a square and each side length is 457mm, 1295mm distance from the lower side of the window to floor, 1143mm distance from right of the window to the wall;

5.    Air inlets: which size are 559×343mm, 914×305mm, 2438×343mm;

6.    Exhaust duct: L9000×φ406mm, install it at the centered in on the right side of the cube hood

7.    Cable tray: H2400mm, the rundle as a square which size is L305×W25×D25, and both rundles distance is 299mm;

8.    Burner: L341mm×D30mm with 242 holes;

9.    Gas flux: 13.2L/min, 0.1Mpa for gas pressure

10. Flux checking: The differential pressure flow-meter sense smoke pipeline flow speed , provide basis for the control of fan speed ;

11. Light transmittance: photocell sense the smoke density during the flaming;

12. Height of flame: Infrared visible light show the current height of the flame real-time;

13. Special software: Draw up the curve by the pip flow, smoke density, height of the flame ,and form a table automatically, through the printer printing
