'Rated' does indeed mean 'stated by the manufacturer' (International
Electrotechnical Vocabulary definition). BUT the manufacturer may, for
some products, state any value that suits, or none at all. In other
cases, the ***conditions under which the power is measured** are defined
differently in different standards applying to the same product, or
defined insufficiently clearly. 

Again, the manufacturer may put one value on the label on the product
and state another, maybe more precise, value in a detailed product data
file sent to a test house. There is limitless scope for confusion and,
in some cases, scope for abuse. As I indicated in another response,
something is going to be done about it, at least for standards produced
by IEC SC77A.
