19、 Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through techn
20、ical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take par
21、t in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different app
22、roval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subj
23、ect of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

This third edition cancels and replaces the second ed
26、ition (ISO/IEC 18000-4:2008), of which it constitutes a minor revision with the following changes: 5.1 has become Clause 5; 5.2 has become Clause 6; 5.3 has been Clause 7; Clause 8 has been introduced; Clause 6 has become Clause 9; Clause 1, Clause 2, Clause 3, Clause 4, Clause 5, and Clause 9 have
27、been revised as necessary to also cover Clause 8.

31、d Technical Reports developed by ISO/IEC JTC 1/SC 31, WG 4 for the identification of items (item management) using radio frequency identification (RFID) technology. This part of ISO/IEC 18000 defines three 2,45 GHz protocols. Each of the specific physical/data link configurations is defined in a sep
32、arate sub-clause. The configuration descriptions include a physical layer and a data link layer. The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this document can involve t
33、he use of patents concerning radio-frequency identification technology given in all parts of the document. ISO and IEC take no position concerning the evidence, validity, and scope of these patent rights. The holders of these patent rights have assured the ISO and IEC that they are willing to negoti
34、ate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statements of the holders of these patent rights are registered with ISO and IEC. Information can be obtained from the following companies. Contact details Patent Hold
