Endoscopes — Medical endoscopes and endotherapy devices — Part 3: Determination of field of view and direction of view of endoscopes with optics
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).

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
