11、 21118:2012ISO/IEC 21118:2012(E) iv ISO/IEC 2012 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technica
12、l committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely wit
13、h the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Inter
14、national Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may
15、 be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/IEC 21118 was prepared by Technical Committee ISO/TC JTC 1, Information technology, Subcommittee SC 28, Office equipment. This second edition cancels and replaces the first edition
16、(ISO/IEC 21118:2005), which has been technically revised.

17、ts for front projection type data projectors and the form of specification sheets. It is also applicable to data projectors that have a video signal input port as well as a computer signal input port. It is not applicable to units for a rear screen projection or with a video input terminal alone. 2
