Yes; but that's to test the lower limit of the specified AC voltage range. (Not to go significantly lower than that limit. Is it not?)
PARD testing on SMPS and linear, uses a variable AC line voltage source... like a Variac autotransformer... to test for tolerance within the specified line input range... but not below it.
