Given an electonic/electrical piece of equipment. Say a refrigerator, copy machine or computer - with the voltage rating on the nameplate. Say 115V, at 15A and 60 hz.

Does UL tests include how the equipment wil repond to a low voltage? Is the sample equipment listed above required to protect itself from a low voltage condition? Is the equipment required to be designed to say not catch fire?

Assume the low voltage was caused by the serving utility during an extended brownout.
 
Low Voltage, UL style

Low Voltage, UL style

Some UL standards require that the appliance under investigation complies with the standard with a low input voltage. This value is either 6% or 10% low. Is this low enough to cover the brownouts you are thinking of?
