If the product is so small that it cannot accomodate a 5mm CE marking, then the
size may be reduced as long as it is clearly legible and not likely to be

That is correct. EU Directives require transposition into the legislation of
the Member States, but EU Regulations have legal effect in their own rights.
Regulations are usually used to add detail to legislation that has already
been implemented in national law.

There may be a number of reasons for this:-
1. To ensure that the disposal instructions can be understood in the countries

Not necesarily. That would depend on how and what the equipment in which the

EU Directives require that records are kept for 10 years after cessation of

Almost certainly a typo. I am fairly certain that they mean IEC60601-1.
