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.
Technical 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*Diameter of 406mm, install it at the centered in on the right side of the cube hood
