Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for
20、identifying any or all such patent rights. NOTE This document has been prepared by experts coming from CEN/TC 331 and UPU, under the framework of the Memorandum of Understanding between the UPU and CEN. This document (CEN/TS 15844-2), is the CEN equivalent of UPU 1)standard S18b-7. It may be amended
21、 only after prior consultation, between CEN/TC 331 and the UPU Standards Board, in accordance with the Memorandum of Understanding between CEN and the UPU. The UPUs contribution to the document was made, by the UPU Standards Board 2)and its sub-groups, in accordance with the rules given in Part V of
22、 the “General information on UPU standards“. 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 Republic, Denmark, Estonia, Finland,
23、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 specialized institution of the United Nati
24、ons 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 total of 425 billion letters-post ite
25、ms 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 to move beyond what is traditionally r
26、egarded 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-related information between posts, and pr
27、omotes 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 such as electronic data interchange (E
28、DI), 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).4 Introduction A general introduction to all parts of the
29、 specification is provided in CEN/TS 15844-1. This part deals only with the encoding of ID-tags in the form of a 78-position bar-no-bar code, BNB-78, printed on the reverse side of items, in area R1, using fluorescent ink. It is arranged under six main headings: Clause No. Description of content 5 U
30、sage limitations requirement for a special issuer code: explains the requirement for issuers wishing to use the BNB-78 ID-tag representation to obtain a special issuer code for this purpose; 6 Value range limitations: defines limitations on the values of data elements used in ID-tags which are to be
31、 represented on items in the form of a BNB-78 bar code; 7 Encoding specification: specifies the construction of a 78-position bar-no-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 itsel
32、f. This clause defines required ink and printing parameters; 9 Reading and interpretation of BNB-78 bar codes: specifies the validation and error correction requirements associated with the reading of ID-tags represented using BNB-78 bar codes; 10 Conversion to the message and binary representations
33、: describes the correspondence between BNB-78 representation and the binary and message interchange representations defined in CEN/TS 15844-1. The above definition is supported by two informative annexes: Error detection and correction algorithms: provides example implementations of the error detect
34、ion and correc-tion algorithms used in encoding and reading the BNB-78 representation of the ID-tag. Other implementations are possible and, depending on the environment, might well be more efficient. The examples nevertheless serve as a possible baseline, and can be used for verifying the correctne
35、ss of a different implementation. S18 ID-tag 78-position BNB bar code template: provides a template which can be used for manual decoding of the data elements in printed BNB-78 representations of an ID-tag. Such manual decoding should be used with caution since, unless the complete bar code is read
36、and processed through the appropriate error detection/correction algorithm, there is no certainty that the value obtained has been read correctly. DD CEN/TS 15844-2:2010CEN/TS 15844-2:2010 (E) 5 1 Scope This part of the Technical Specification defines the representation of ID-tags as a 78-position b
37、ar-no-bar code (BNB-78) printed in fluorescent ink in area R1 on the reverse side of items. BNB-78 encoding is one of two encoding specifications supported by this Technical Specification 3) for the printing of ID-tags in area R1, the other being BNB-62, which is specified in CEN/TS 15844-3. NOTE 1
38、Representation in the form of a 4-state code printed on the front of the item is covered in CEN/TS 15844-4 for flats and CEN/TS 15844-5 for small letters. BNB-78 encoding supersedes the earlier specified BNB-62 encoding and shall be applied in all cases in which ID-tags are placed in area R1 on the
39、reverse side of letter mail items of size up to and including C5, by issuers other than those explicitly authorised to continue use of BNB-62 encoding, namely An Post (Ireland), Canada Post and United States Postal Service. NOTE 2 ID-tags encoded in area R1 are required by article RL 123 of the UPU
40、Letter Post Regulations 1 to be compliant with UPU standard S18 and by this with the related CEN/TS 15844. This supports only two encodings in area R1, namely BNB-78 as defined herein and BNB-62 as defined in CEN/TS 15844-3. The latter is authorised for continued use only by the three issuers mentio
41、ned above. Where ID-tags are used, and are applied in area R1 on the reverse side of letter mail items of size up to and including C5, the use of BNB-78 encoding is mandatory for all other issuers. NOTE 3 BNB-78 encoding is not considered suitable for use on flats. CEN/TS 15844-4 defines a 4-state e
42、ncoding which may be used for this purpose. 2 Normative references The following referenced documents are indispensable for the application of this document.

DD CEN/TS 15844-2:2010CEN/TS 15844-2:2010 (E) 6 5 Usage limitations Requirement for a
46、special issuer code The allocation of ID-tags and their application to items using BNB-78 representation is restricted to issuers to whom an issuer code in the range NNN, , ZZZ has been assigned. Issuers wishing to commence use of the ID-tag should request the UPU Standards Board secretariat to issu
47、e them with such a code at least three months prior to the planned implementation date. NOTE 1 There are no constraints on the reading and use of ID-tags. Any mail handling organisation with appropriate reading equipment may read ID-tags on items and use these for their intended purposes. However, t
48、he allocation of ID-tags and their encoding on items is restricted to licensed issuers which have requested and obtained an appropriate issuer code, together with their designated agents. NOTE 2 Issuer codes are allocated in accordance with UPU standard S31. The Standards Board secretariat will need
49、 information on the applicants mail processing infrastructure (number of main processing facilities, sorting offices, etc.) in order to determine the number of issuer codes required and to select the most appropriate code value(s). NOTE 3 The supported range allows for the identification of up to 2 197 (13*13*13) issuers, out of the range of 33 696 covered by UPU standard S31. Many high-volume generators of ID-tags, with multiple processing facilities, are expected to require several
