I think it would be reasonable to expect that a product marked 100-240 Vac and
as compliant with 62368-1 would have been tested, where specified in the
standard to test to the "most unfavorable supply voltage," to values in the
90-264 range. If in doubt, you could ask the manufacturer.

Hello experts,
I'm looking for a consultant who can audit a client's facility in Zurich
Switzerland regarding employee health and safety procedures. I'm thinking
such a consultant would be based in the USA or the UK, but am open to all
comers. Any leads you can provide will be appreciated.
– extremes of rated voltage ranges; and
So the rated voltage range is 100V to 240V
– tolerance *on* rated voltage as declared by the manufacturer.
"Unless the manufacturer declares a wider tolerance, the minimum
tolerance shall be taken as +10 % and −10 % for AC mains"
So
Thank you Bernd, Mike and everyone else who replied with your helpful comments.
I think my dilemma concerns the interpretation of the rated voltage tolerance
in relation to the consideration of supply voltage for testing under clause
B.2.3 in IEC62368-1. The clause looks unchanged since 2014
