BS EN 14508:2016EN 14508:2016 (E) 4 Introduction In the Green paper on postal services in 1992 the European Commission emphasized the need to establish common rules for the development of community postal services and the improvement
22、of quality of service. The Commission identified requirements for quality of service measurement that include: independent end-to-end measurement capabilities; a focus on cross-border delivery service performance; a single, uniform and reliable system for monitoring delivery service performance with
23、in the European Union. The European Commission acknowledged that the different postal traditions and cultures in Europe would not allow for the establishment of one common unified European measurement system and that national systems should have sufficient degrees of freedom to reflect national need
24、s and peculiarities. On the other hand, they should fulfil a defined set of minimum requirements to satisfy the information interests of the national regulatory authority, postal customers and postal operators themselves. The objective of the measurement is to estimate the transit time quality of se
25、rvice given to the customer in each European country domestically and cross-border between the European countries. This European Standard refers to a number of principles and minimum requirements to be applied for the measurement of the transit time of single piece non-priority mail. This European S
26、tandard for single piece non-priority mail has been developed from 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. Both standards consider methods using a representative end-to-end sample
27、 of addressed letter mail. The additional specifications in this European Standard are required to define the minimum confidence levels for the measurement of non-priority mail. When EN 14508 was first developed it was decided to base it on existing measuring systems already in use among the Europea
28、n Union member states. The expansion of the European Union increased the number of cross-border mail flows and the standard was adapted in 2007 to make it possible to economically measure a larger number of mail flows from a wider range of countries. This was achieved by categorizing mail flows for
29、measuring purposes and extending the measurement over a consecutive number of years. In the earlier versions of EN 13850 and EN 14508 the requirements for the Minimum Sample Size (MSS) were given in terms of accuracy requirements for domestic and cross-border measurement systems. The basis of this w
30、as an accuracy calculation method which linked any accuracy requirement directly to a corresponding MSS. The improved accuracy calculation method in EN 13850:2012 introduced a number of consequences which made it difficult to hold up this link. Annex B explains these consequences and how they have b
31、een overcome. BS EN 14508:2016EN 14508:2016 (E) 5 1 Scope 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-
32、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 offe
33、red 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 ma
34、y 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 directive1. This European St
35、andard 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 sortin
36、g 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 se
37、rvices 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). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and

42、y EXAMPLE second class item, B class item. 4 Methodology 4.1 General The system for measuring the distribution of the end-to-end transit time of non-priority single piece mail items shall be robust and shall give statistical measurements at a defined level of accuracy. The methodology shall comply w
43、ith the requirements of EN 13850:2012. In particular the following requirements of EN 13850:2012 shall apply, but shall refer to non-priority instead of priority: The sample design shall be representative of real non-priority single piece mail flows. The measurement system shall provide one annual f
44、igure for each relevant field of study using a test period of 1 year, 2 years or 3 years according to Annex A. NOTE For cross border mail flows in categories 2 or 3 according to Annex A it will take 2 or 3 years, respectively to reach the required accuracy for the particular size of mail flow. The f
45、ield of study shall be defined and used consistently throughout the measurement. A field of study shall not be modified during a yearly test period or over the full period of the years needed for full accuracy. The measuring methodology shall be objective and shall be audited. All measurements of tr
46、ansit time shall refer to end-to-end transit time. The measurement system shall be continuous. Panels of senders and receivers shall be independent of postal service operators and regulatory authority and shall be managed according to the International Chamber of Commerce / ESOMAR International Code
47、 of Marketing and Social Research Practice including its attachment. In addition, all requirements regarding integrity of the measurement shall follow EN 13850:2012, 6.6. 4.2 Calculation and presentation of transit time The transit time of a postal item shall be measured in units of days and express
48、ed as (J + n) days. J is the date of deposit provided posting takes place before the published last collection time at the point of induction of the mail. For the purpose of this European Standard, transit times for domestic and cross-border mail shall be calculated according to a five-day working w
49、eek calculation rule; whereby Saturdays, Sundays, and national holidays in the country of delivery are subtracted, in accordance with EN 13850:2012, B.1. For domestic mail, the transit times may, in addition, be calculated according to the weekend collection and delivery pattern provided, in accordance with one of the other calculation rules of EN 13850:2012, Annex B, subject to the requirements of the national regulatory authority. BS EN 14508:2016EN 14508:2016 (E) 7 In the cross-border case it shall be continuous for a field of study over the full p
