9、ber bodies). The work of preparing International Standards is normally carried out through ISO technical 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, governmen
10、tal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance
11、are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO 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).Attention is
12、 drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO 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
13、 on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity asses

15、cond edition cancels and replaces the first edition (ISO 141322:2002), which has been technically revised with the following changes:a) the term “telescopic system” has been introduced replacing the term “telescope” where appropriate;b) clearer distinction between “b distance between centres of eyep
16、ieces”, “b interpupillary distance” and “B distance between centres of objectives”, see 3.1.11 and 3.1.14;c) the previous term “wideangle binocular” is now defined in ISO 14132-1 as “wide angle telescopic system”;d) a new term was added: “false pupils” (3.5).ISO 14132 consists of the following parts
