F21H

INCANDESCENT MANTLES; OTHER INCANDESCENT BODIES HEATED BY COMBUSTION

Description

F21H covers incandescent mantles and other luminous or heat-emitting bodies that operate by heating through direct combustion or flame exposure. This includes gas mantles (typically thorium oxide or similar refractory materials), burner designs for mantle lighting systems, and the structural elements that support incandescent bodies in combustion-based lamps. The classification encompasses both the mantles themselves and the apparatus for maintaining and igniting them, but excludes electric incandescent lamps and non-incandescent combustion lighting (covered under other F21 subclasses).
