Raymond,
I can confirm that such a 'memo' was issued, since I recall
discussing it with a colleague in a UK notified body at the time
(circa 1994). As I recall, it resulted from a meeting of whatever
forum represents LVD Notified Bodies in the UK shortly after the
document declaring an intent to harmonise UK voltage with the rest of
the EU was issued.
The objective was to ensure that products are properly tested even
for those areas where the supply voltage has not yet been reduced to
230V. The standards (esp. 60335-1) don't really cope with this well
since they set test voltage limits based on a percentage of the
manufacturer's stated rated voltage, not on fixed voltage values.
Therefore, manufacturers could squeeze an appliance past the tests by
stating a lower limit (e.g. 230V instead of 220-240V). This makes a
surprising amount of difference, especially for high power heating
appliances such as electric kettles (believe me, this is one smoke
signal I do know how to read!)
Ask one of the notified bodies you deal with in the UK on a regular
basis and they should be able to come up with a copy of the memo.
Failing that, let me know and I'll see what I can get for you.
Regards
Nick.

A few years ago, BEAMA or other similar body has issued a memo to public
laboratories about testing voltage for products selling in the U.K. The memo
says the U.K. mains is still 240Vac although the rated voltage is agreed to be
230Vac and the products have to be taken care the safety at 240Vac.
Can anyone
tell me where I can find a copy of this memo and if there is any
updated version
to replace this one.
Thanks and regards,
