True but in that case you are concerned with making sure the enclosure material is not a potential ignition source so in most cases you can use UL94-HB material. It is not related to the enclosure providing a fire barrier although it can provide that function by default. UL 60065 includes U.S. specific deviations where a fire enclosure is required if available power in the product exceeds 15W under normal and fault conditions....In this case you need an enclosure rated UL94-V2 or better..... There are standard changes being proposed, and in the works driven by the U.S. State Fire Marshals, to protect against external flame sources like candles where a 94-V0 fire enclosure may be required if adopted...

There are requirements for the flammability of materials as well as distances from sources of ignition top and bottom. Maybe not a Fire Enclosure, but certainly a Fire Envelope.
