scope:

The UL flame exposure is a vertical-tray fire test for determining values of cable damage height and smoke release from electrical and optical-fiber cables when the cables are subjected to a flaming ignition source. For a cable to be acceptable under the UL test procedure, each of the following is to be exhibited (see 10.1 and 10.2):

a) The cable char height is to be less than 8 ft, 0 inch (244 cm) when measured from the bottom of the cable tray in accordance with Section 8.

b) The total smoke released is to be 95 m2 or less.

c) The peak smoke release rate is to be 0.25 m2/s or less.

The purpose of this test is to determine flame propagation and smoke characteristics of these cables to qualify the cables for the limited smoke marking.

This test does not investigate the toxicity of the products of combustion or decomposition.

This test does not cover the constructional requirements for the cable or any electrical, optical, or other performance requirements for the cable.
