Ages ago when I worked at another company that shipped products to Japan, their unwritten rule was to design in power supplies that operated without problems at 85 Vac, and that had better be designed/tested down to 80 Vac, because of the continued brown-out conditions in Japan. It seems nothing much has changed.
I don't remember what was stated about the frequency tolerance.

We have a product that "stumbles" when the input voltage/freq is 90V/47Hz. My question is.. Is this a reasonable test combo? Does anyone know of a country that falls in this range? --------- This message is coming from the emc-pstc discussion list.
