Hi Phil,
IEC 60038 defines the standard nominal voltages, but that doesn’t necessarily
reflect the reality on the ground. IEC operates the “World plugs” web page that
gives the national standard voltages and plugs used by country:

It is typical for many standards to run voltage sensitive tests (temperature
rise, for example, as I recall) at the labeled voltage PLUS a percentage (6 to
10 %, as I recall). That percentage is intended to cover the utility supply
tolerances.
So a product labeled 100-240 Vac will
Please could someone advise me on what standard, if any, might compel a
manufacturer to rate the operating voltage of their equipment to at least cover
the utility supply tolerance of the region in which it is being sold?
For example, a DoC for an IT item sold in the UK claims conformance with
