18、all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards,
19、Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory
20、 work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations
21、. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recom
22、mendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by an
23、y end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional pub
24、lication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by indep
25、endent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any
26、personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative
27、 references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsibl
28、e for identifying any or all such patent rights. International Standard IEC 63080 has been prepared by IEC technical committee 100: Audio, video and multimedia systems and equipment. ITU-T F.791:2015 has served as a basis for the elaboration of this standard. The text of this International Standard
29、is based on the following documents: CDV Report on voting 100/2775/CDV 100/2873/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directiv
30、es, Part 2. IEC 63080:2017 IEC 2017 5 The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, w
31、ithdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 6 IEC 63080:2017 IEC 2017 INTRODUCTION This document defines words describing accessibility, disability, and technical terms to be used for improving the writing in relation to
32、 standardization, and to facilitate accurately the needs and the mainstreaming of accessibility in standards that will include persons with disabilities (PWD), older persons with age-related disabilities and persons with specific needs. See WTDC Res. 58, WTDC AP and ITUT F.790, listed in the Bibliog
33、raphy. With the advent of the United Nations Convention on the Rights of Persons with Disabilities (see UNCRPD in the Bibliography), its passage in 2006, and its ratification by numerous countries, many new terms and definitions were created. Some of these terms and definitions were created at the b
34、ehest of PWD themselves to eradicate terms that were demeaning, insulting, and inaccurate. Writers of standards are able to mainstream accessibility features into standards, as well as to write specific standards for accessibility. To design products and services successfully, there is a need for a
35、common language. This document is intended to give definitions so that it will make it easier for industries to implement these accessibility features and accessibility standards if everyone is using the same language and vocabulary. It is also important that governments, government agencies, non-go
36、vernment organizations (NGOs), the UN, and its respective agencies normalize these terms for their integration into mainstream everyday language. The UN Convention on the Rights of Persons with Disabilities (UNCRPD), Article 9, made clear the need to include PWD, older persons with age-related disab
37、ilities, and persons with specific needs by mainstreaming them into all aspects of modern life. This can only be done by including them in the design of modern technology and information and communication technologies (ICTs) using universal design as defined in the UNCRPD and using a common language
38、 and vocabulary. IEC 63080:2017 IEC 2017 7 ACCESSIBILITY TERMS AND DEFINITIONS 1 Scope This document contains a list of currently used terminology to describe accessibility and terms that writers of standards need when writing and designing International Standards. It is important to standardize and
39、 define a recognized list of the terms already used and in existing ITU Recommendations and Resolutions, along with those in the UN Convention on the Rights of Persons with Disabilities (UNCRPD). Without such a list, there could be confusion not only on the part of writers and implementers of standa
40、rds, but also by the public at large. It is also important to eliminate terminology that is no longer used, offensive, and demeaning to persons with disabilities (PWD) and others. The terminology in this document is for use in international work when English is used to refer to telecommunication/ICT
41、 accessibility matters. This document is also applicable to everyday life and all usages, including web design and other writings, as well as ICT, telecommunications, and broadcasting standardization. The aim is for it to also be mainstreamed into future policy, regulatory, and academic documents so
42、 as to be consistent with global compatibility and understanding. In the future, work that is yet to be created, written, or approved could include new terms that are added as appropriate by consensus in a revision. 2 Normative references There are no normative references in this document. 3 Terms a
