ISO/DIS 14134
Foreword

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 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, governmental 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.

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 International 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 be the subject of patent rights.

ISO shall not be held responsible for identifying any or all such patent rights.

ISO 14134 was prepared by Technical Committee ISO/TC 172, Optics and optical instruments, Subcommittee

SC 4, Telescopic systems.

DRAFT INTERNATIONAL STANDARD ISO/DIS 14134
Optics and optical instruments — Specifications for astronomical
telescopes
1 Scope

This International Standard applies to astronomical telescopes, including finder telescopes, and to their functional

specifications.

These specifications are restricted to the amateur astronomical telescopes, which should be distinguished from

simple amusement telescopes, and give information about astronomical telescopes of commercial apertures.

2 Normative references

The following normative documents contain provisions which, through references in this text, constitute provisions

of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
