Hello Eric,
Some companies have environmental test programs that subject their products to
all types of power line conditions that are not covered in regulatory
requirements. As far as line voltage tolerance testing, this depends on the
specifications you publish externally for your products.
Ages ago I had a product that had a couple of socketed relays in the
primary. What we did was create special shorted relays that were used in
place of the regular relays during hipot. You may consider doing this if
your relays are socketed.
