scope:

This European Standard specifies methods for measuring the end-to-end transit time of the domestic and crossborder, priority and non-priority, bulk mail, collected, processed and distributed by postal service operators.

End-to-end is defined as from the point mail is placed into the collection/acceptance system under the responsibility of the postal operators, to the final delivery point under the responsibility of the postal operators.
