New UL Requirements
Underwriters Laboratories tightened its safety requirements for halogen torchieres in 1997 and revised them again effective June 1, 1999. Among the new requirements are:
- A glass or wire guard that keeps objects at least 3 inches (7.6 centimeters) away from the lamp must be affixed over the lamp (inside the bowl of the torchiere). The guard must be attached at the factory; it cannot be left loose in the box for the consumer to attach.
- To test the torchiere, UL drapes a 20-layer pad of cheesecloth over the guard for seven hours while the lamp is on. The cheesecloth must not ignite or develop holes in any of its layers.
- The torchiere should have a switch that turns the unit off when it falls over in any direction. If the torchiere does not have the switch, it must pass additional stability requirements and a vertical wall test. In the vertical wall test, the lamp is laid on its side for seven hours next to a simulated wall of plywood covered in cotton terrycloth. The cloth and plywood must not flame or char.
- The fixture must bear a manufacture date.
