Ul cable vertical-tray flaming test room

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*Ø406mm, 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: L341*30mm 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 14.Control system: 5.7inch color touch screen, PLC from Japanese Panasonic, SCM, 16 bits high-performance AD transform etc Polywood case
