In addition to EN 13850:2012 Postal Services – Quality of Service – Measurement of the transit time of end-to-end services for single piece priority mail and first class mail, this European Standard specifies methods for measuring the end-to-end transit time of domestic and cross-border non-priority single piece mail, collected, processed and delivered by postal service operators. It considers methods using a representative end-to-end sample of all types of single piece addressed letter mail with defined transit-time service levels offered to the customer. This standard is applicable to the measurement of End-to-End single piece non-priority mail services.
This European Standard has been developed from and is compatible with the requirements of EN 13850:2012. As such, surveys for both priority and non-priority single piece mail may be undertaken concurrently while reporting separate estimates of priority and non-priority transit times.
The overall transit time quality-of-service result is to be expressed as the percentage of mail delivered within (J + n) days end-to-end according to the EU Postal directive .
This European Standard relates to the measurement of so-called “normal” services given to private persons / households and smaller businesses that post mail at street letter boxes, over the counter at post offices, have bring services from their offices or give their mail directly at postal service operators’ sorting centres.
For technical reasons this European Standard may not in all parts be suitable for the measurement of very small volumes of mail and for operators with limited coverage.
This European Standard is not applicable for measuring the end-to-end transit time distribution of large bulk mailers’ services or hybrid mail, which require different measurement systems and methodologies; (see, for example, EN 14534 Measurement of the transit time of end-to-end services of bulk mail).
