This document forms Part 4 of a multi-p
20、art CEN/TS 15844, Postal services ID-tagging of letter-mail items. It should be read in conjunction with the main body of the specification, Part 1. The present document provides a specification of the encoding of S18 ID-tags using a 4-state symbology that may be applied to flats. CEN/TS 15844-5 pro
21、vides a similar specification for application to the front side of small letters. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
22、Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. 1)The Universal Postal Union (UPU) is the speci
23、alized institution of the United Nations that regulates the universal postal service. The postal services of its 189 member countries form the largest physical distribution network in the world. Some 5 million postal employees working in over 660 000 post offices all over the world handle an annual
24、total of 425 billion letters-post items in the domestic service and almost 6,7 billion in the international service. Some 4,5 billion parcels are sent by post annually. Keeping pace with the changing communications market, posts are increasingly using new communication and information technologies t
25、o move beyond what is traditionally regarded as their core postal business. They are meeting higher customer expectations with an expanded range of products and value-added services.2)The UPUs Standards Board develops and maintains a growing number of standards to improve the exchange of postal-rela
26、ted information between posts, and promotes the compatibility of UPU and international postal initiatives. It works closely with posts, customers, suppliers and other partners, including various international organizations. The Standards Board ensures that coherent standards are developed in areas s
27、uch as electronic data interchange (EDI), mail encoding, postal forms and meters. UPU standards are published in accordance with the rules given in Part VII of the General information on UPU standards, which may be freely downloaded from the UPU world-wide web site (www.upu.int).DD CEN/TS 15844-4:20
28、10CEN/TS 15844-4:2010 (E) 4 Introduction A general introduction to all parts of the Technical Specification is provided in CEN/TS 15844-1. This part deals only with the encoding of ID-tags in the form of a 4-state bar code printed on the front side of flats. It is arranged under six main headings: C
29、lause No. Description of content 5 Usage limitations: defines limitations on the use of the Postal-4i encoding of ID-tags specified in this document. 6 Value range limitations: defines limitations on the values of data elements used in ID-tags which are to be represented on flats in the form of a Po
30、stal-4i bar code. 7 Encoding specification: specifies the construction of a Postal-4i bar code from ID-tag data elements. 8 Printing of the bar code: to allow the association of computer data with a physical item, the ID-tag is printed on the item itself. This clause defines required ink and printin
31、g parameters. 9 Reading and interpretation of Postal-4i bar codes: specifies the validation and error correction requirements associated with the reading of ID-tags represented using Postal-4i bar codes. 10 Conversion to the message and binary representations: describes the correspondence between Po
32、stal-4i bar coded representation and the binary and message interchange representations defined in CEN/TS 15844-1. These are complemented by two informative annexes, the first providing references to an example implementation of the Postal-4i ID-tag generation algorithm and the second providing a nu
33、mber of example ID-tags, generated using this implementation. DD CEN/TS 15844-4:2010CEN/TS 15844-4:2010 (E) 5 1 Scope This part of the Technical Specification defines the representation of ID-tags as a Postal-4i symbology 4-state bar code printed on the front side of flats. Many of the provisions ar
34、e applicable also to small letters and are therefore referenced by Part 5 of the specification (CEN/TS 15844-5), which covers these. Postal-4i symbology 4-state encoding is the only encoding specification supported by this Technical Specification 3) for the printing of ID-tags on the front of items.
35、 NOTE Representation in the form of fluorescent BNB bar codes printed on the reverse side of small letters (not flats) is covered in CEN/TS 15844-2 and CEN/TS 15844-3. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated referenc
36、es, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

37、s use for the encoding of data on postal items 3 Terms and definitions A number of common terms used in this document are defined in the UPU Standards glossary, in documents referred to in normative references and in the bibliography. Definition of frequently used or particularly important terms as
38、well as other terms introduced in this document are given below. See CEN/TS 15844-1:2010. 4 Symbols and abbreviations See CEN/TS 15844-1:2010. 5 Usage limitations The 4-state bar coded representation of ID-tags defined in this part of the specification is intended for use only in area F4 or F4X on t
39、he front side of flats; it shall not be used in area R1 on the reverse side. NOTE Usage in other areas on the front could result in interference with, or by, codes placed by other systems. Usage on the reverse side, and particularly usage in area R1, could seriously disturb the operation of older sy
40、stems which are designed to work only with BNB encodings of ID-tags. 3)References to “this Technical Specification“ should be interpreted as references to CEN/TS 15844 as a whole, not only to Part 4. DD CEN/TS 15844-4:2010CEN/TS 15844-4:2010 (E) 6 6 Value range limitations In addition to the compone
41、nt value limitations defined in CEN/TS 15844-1, the following limitations apply to ID-tags which are to be represented in the form of Postal-4i symbology bar codes: the format identifier is limited to the values 18C and 18D, the choice between these being dependent on the data content of the ID-tag
42、value (see CEN/TS 15844-1), in turn dependent on the method of ID-tag allocation: format 18C shall not be used on pre-printed labels; NOTE 1 Format 18C explicitly includes a date/time of ID-tag value generation and is intended for use only in situations in which the ID-tag value is dynamically assig
43、ned at the time of its application to an item. Pre-printed labels might be produced long before their application to items and may therefore use only format 18D. the use of domain codes is recommended, but not required. NOTE 2 That is, it is recommended, though not required, that users allocate equi
44、pment identifiers in such a way that the first character indicates the allocation domain, normally corresponding to the geographic region or group of postal processing facilities in which the equipment which issued the ID-tag is situated. If this is done, and the domain table published, other organi
45、sations which read the ID-tags can determine the geographic origin of the item and apply appropriate procedures to determine whether the item has suffered any exceptional delay. 7 Encoding specification The bar code shall be generated in compliance with UPU standard S48, using the following paramete
46、rs: 1) format code (f) value: equal to bits 0-3 of the binary ID-tag value, as defined in CEN/TS 15844-1; NOTE 1 This assists in distinguishing Postal-4i ID-tags from other bar codes which use Postal-4i symbology. See S48 for a definition of the symbology parameters f, l, r, c and n. 2) left synchro
47、nisation code (l) value : 010110 (22 decimal); 3) right synchronisation code (r) value : 100110 (38 decimal); NOTE 2 The synchronisation codes are inserted to provide known patterns, separated by a fixed number of bar positions in the final bar code, which can be used for checking synchronisation of
48、 captured bar codes. The particular binary patterns and their position have been chosen: (a) to support detection of bar code orientation and (b) to minimise the probability of read errors occurring in the synchronisation codewords themselves. Thus, they are not situated at the ends of the final bar
49、 code and use only 4-state ascenders and descenders, which are less prone to read errors than full bars or timing signals. The chosen values also assist in distinguishing Postal-4i ID-tags from other bar codes which use Postal-4i symbology. 4) number of variable data codewords (c) value: 13; 5) bar code length (n): 75 if the resulting ID-tag is to be printed directly on the item; 57 or 75 if the ID-tag is to be printed on a label; NOTE 3 Use of a 57 bar ID-tag on labels is an option, not a requirement: it is permitted to use the
