Product introduction of the UL Cable Vertical-Tray Flammability Tester
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.
Standards
According to the clause 9.6 & 9.7 of UL1685-2007, UL2556-2007
How are fire protection products tested?
Many fire tests are run by official laboratories for the purpose of product certification. However, some manufacturers of fire protection products also maintain their own facilities and run tests for R & D purposes before going to the expense and exposure of a test at a third-party facility.
What is UL 1685?
UL 1685 is a smoke-release test for electrical and optical-fiber cables to determine their flame growth and smoke characteristics, which qualify them for limited smoke marking.
