Endoscopes -- Medical endoscopes and endotherapy devices

This document applies to endoscopes designed for use in the practice of medicine. It specifies measurement requirements and describes two test methods for measuring the field of view and direction of view of endoscopes. Method A uses the distance from the distal window to calculate the field of view. Method B uses the distance from the entrance pupil. Other test methods can be used if they obtain equivalent results.

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.

The procedures used to develop this document and those intended for its further maintenance 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 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

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.

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

The committee responsible for this document is ISO/TC 172, Optics and photonics, Subcommittee SC 5,

Microscopes and endoscopes.

This second edition cancels and replaces the first edition (ISO 8600-3:1997). It also incorporates the

Amendment ISO 8600-3:1997/Amd 1:2003.

Determination of field of view and direction of view of
endoscopes with optics
1 Scope

This document applies to endoscopes designed for use in the practice of medicine. It specifies

measurement requirements and describes two test methods for measuring the field of view and

direction of view of endoscopes. Method A uses the distance from the distal window to calculate the

field of view. Method B uses the distance from the entrance pupil. Other test methods can be used if

they obtain equivalent results.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 8600-1 and ISO 8600-6 apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

4 Requirements
4.1 General

Method A applies only if the measuring distance is at least 30 times larger than the distance between the

[1]

distal end and the entrance pupil and the accuracy requirement in ISO 8600-1 is satisfied. Otherwise,

the error caused by the distance between the distal end and the entrance pupil in Method A will lead to

a systematic measurement error.

Method B may be used at any distance. In general, any method is allowed which has the entrance pupil

as reference. Details about test Method A and Method B for measuring endoscope field of view and

direction of view, inc
