IS0/IEC/IEEE 8802-3:2021/Amd.14:2022(E) 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 technical committees established by the respective organization to deal with particular fields of technical activity ISso 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 part in the work. 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 approval criteria needed for the different types of Iso/IEC documents 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 or www.iec.ch/members experts/refdocs). IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Attention is drawn to the possibility that some of the elements of this document may be the subject 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) or the IEC list of patent declarations received (see https://patents.iec.ch). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement. For an explanation of the voluntary nature of standards, the meaning of Iso specific terms and expressions related to conformity assessment, as well
