I think the conclusion is acceptable. We should then draw another
conclusion NOT to limit the category class enumeration to the values of
EN15528 to allow country-specific values as CE or CM2.
As you wrote, the category classes are rather ‘political’, so no need to
avoid the country-specific values. As shown above, one cannot draw a
‘hard’, ‘automatic’ technical conclusion (concerning acceptance of
certain vehicles) from a line’s classification, so the country-specific
should do no further harm.
Best regards,
Dirk.
