Foreword
This document (EN 13850:2002/prA1:2005) has been prepared by Technical Committee CEN/TC 331 “Postal
services”, the secretariat of which is held by NEN.

Introduction
When EN 13850 Postal service – Quality of service – Measurement of the transit time of end-to-end services
for single piece priority mail and first class mail was developed it was decided to base it on existing measuring
systems already in use among the European Union member states. Since the publication of EN 13850 in 2002
more countries have joined the European Union which have increased the number of cross-border mail flows
significantly and therefore made it necessary to adapt the standard accordingly.
This amendment to the standard has been developed to make it possible to economically measure a larger
number of mail flows from a wider range of countries than the original versions of the standard were made for.
The Amendment gives information on how to categorize mail flows for measuring purposes and explain how
required accuracy for small and medium sized mail flows can be obtained by measuring under a consecutive
number of years.

Add the following
using a test period of 1, 2 or 3 years according to Annex F. (Note)
For cross border mail flows in categories 2 or 3 according to Annex F it will take 2 or 3 years, respectively to
reach the required accuracy for the particular size of mail flow.

Page 12, subclause 4.1 after 8 paragraph
Add the following
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.
Page 12, end of subclause 4.2.2
Add the following
In the cross-border case it shall be continuous for a field of study over the full period of the years needed for
full accuracy. This does not necessarily mean that for cross-border mail flows all dates in a year must be
covered. For example, it may be sufficient to select three out of five possible induction days randomly or
according to a systematic rotation plan in each week of the year.
th
Page 14, just above the 4 paragraph from the end of subclause 5.3
Add the following
Note: The intrinsic accuracy of the real mail studies may therefore be lower for those fields of study where less
measurement accuracy is required.
Page 15, end of subclause 5.4.4
Add the following
For cross-border mail flows in categories 2 or 3 according to Annex F, the representative stratification does
not have to be achieved annually but it should be tried to come as close as possible in order to be able to
reach a representative stratification for each full multi-year result.

EN 13850:2002/prA1:2005 (E)
For cross-border mails flows in categories 2 or 3 according to Annex F the annual sample sizes that compose
a multi-year result shall be spread evenly over the test period and not differ relatively by more or less than
20% in any one year.
If the survey design is changed during the test period then checks shall be made that the results of the survey
before and after the design change shall be combined in a way which is representative of real mail.

For cross-border mail flows in categories 2 or 3 according to Annex F, the results shall be cumulative over 2 or
3 years during the test period according to Annex F.
Page 18, end of subclause 5.7.2
Add the following
Due to small sample sizes for countries in categories 2 and 3, see Annex F, for domestic measurement, the
above constraints are relaxed to an interval of [0,2 ; 5] and a maximum relative deviation of 30% and only
when relevant.
For cross-border mail flows in categories 2 or 3 according to Annex F, the above constraints do not have to be
fulfilled annually but only per full multi-year result and only when relevant.
