10、dwide 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.ISO and IEC technical committees collaborate in
11、fields of mutual interest.Other international organizations,governmental and non-governmental,in liaison with ISO and IEC,also take part in the work.In the field of information technology,ISO and IEC have established a joint technical committee,ISO/IEC JTC 1.International Standards are drafted in ac
12、cordance with the rules given in the ISO/IEC Directives,Part 2.The main task of the joint technical committee is to prepare International Standards.Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.Publication as an International Stan
13、dard requires approval by at least 75%of the national bodies casting a vote.In exceptional circumstances,the joint technical committee may propose the publication of a Technical Report of one of the following types:type 1,when the required support cannot be obtained for the publication of an Interna
14、tional Standard,despite repeated efforts;type 2,when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an International Standard;type 3,when the joint technical committee has collected data of a differe
15、nt kind from that which is normally published as an International Standard(“state of the art”,for example).Technical Reports of types 1 and 2 are subject to review within three years of publication,to decide whether they can be transformed into International Standards.Technical Reports of type 3 do
16、not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.ISO and IEC shall not be held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.ISO/IEC TR 24715,which is a Technical Report of type 3,was prepared by Joint Technical Committee ISO/IEC JTC 1,Information technology,Subcommittee SC 22,Programming languages,their env
