The above exemption is for components in fire enclosures, but I guess that Paul is asking of the enclosure itself. In general, if the enclosure contains something which need fire enclosure to reduce the risk of fire hazard, the enclosure should be a fire enclosure hence should UL94 V-1 or better. Parts not requiring a fire enclosure are defined in the standards, and everything else will need a fire enclosure.
