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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information.
The committee responsible for this document is ISO/TC 172, Optics and photonics, Subcommittee SC 5,
Microscopes and endoscopes.
This fourth edition cancels and replaces the third edition (ISO 8600-1:2013), of which it constitutes
a minor revision in order to update the definition and the corresponding Figure 1 for the term
“field of view”.
ISO 8600 consists of the following parts, under the general title Endoscopes — Medical endoscopes and
endotherapy devices:
— Part 1: General requirements
— Part 2: Particular requirements for rigid bronchoscopes
— Part 3: Determination of field of view and direction of view of endoscopes with optics
— Part 4: Determination of maximum width of insertion portion
— Part 5: Determination of optical resolution of rigid endoscopes with optics
— Part 6: Vocabulary
— Part 7: Basic requirements for medical endoscopes of water-resistant type

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
endoscope
medical instrument having viewing means, with or without optics, introduced into a body cavity
through a natural or surgically created body opening for examination, diagnosis, or therapy
Note 1 to entry: Endoscopes may be of rigid or flexible type; all types may have different image pick-up systems
(e.g. via lenses or ultrasonic sensors) and different image-transmitting systems (e.g. optical, via lenses, or fibre
bundles, or electrical).
Note 2 to entry: See also ISO 8600-6.

ISO 8600-1:2015(E)

3.2
endotherapy device
medical device intended to be inserted into a natural or surgically created body opening during
endoscopic procedures, whether through the same or a different orifice from the endoscope (3.1) for
examination, diagnosis, or therapy
Note 1 to entry: Endotherapy devices include the instrument to create the body opening and through which
an endoscope (3.1) or endotherapy device is inserted, such as a guide tube, trocar pin, trocar sleeve, or sliding
tube. Endotherapy devices include the devices to be inserted through the openings other than the opening for an
endoscope (3.1), to ensure the safety of the devices for the intended use under the endoscopic view.
Note 2 to entry: See also ISO 8600-6.
3.3
rigid endoscope (endotherapy device)
endoscope (3.1) or endotherapy device (3.2) whose insertion portion is intended to be unyielding to
natural or surgically created body cavities or instrument channels (3.8)
Note 1 to entry: See also ISO 8600-6.
3.4
flexible endoscope (endotherapy device)
endoscope (3.1) or endotherapy device (3.2) whose insertion portion is intended to conform to natural or
surgically created body cavities or instrument channels (3.8)
Note 1 to entry: See also ISO 8600-6.
3.5
French
Charrière
Fr
measure of the size of certain circular or non-circular cross-section endoscopes defined as
Fr= 3u π
where
u is the perimeter of the cross-section, expressed in millimetres
Note 1 to entry: See also ISO 8600-6.
3.6
distal
any location of that portion of an endoscope (3.1) or endotherapy device (3.2) which is farther from the
user than some referenced point
Note 1 to entry: See also ISO 8600-6.
3.7
proximal
any location of that portion of an endoscope (3.1) or endotherapy device (3.2) which is closer to the user
than some referenced point
Note 1 to entry: See also ISO 8600-6.
3.8
instrument channel
portion of an endoscope (3.1) or endotherapy device (3.2) through which an endoscope or an endotherapy
device is intended to pass

insertion portion
insertion tube
portion of an endoscope (3.1) or endotherapy device (3.2) which is intended to be inserted into a natural

insertion portion (3.9) to be inserted
Note 1 to entry: The maximum width of any expandable or transformable portion of the insertion portion is not
considered as a maximum insertion portion width, such as balloons, controllable parts, jaws and the like having
variable insertion portion widths.
Note 2 to entry: See also ISO 8600-6.
3.11
minimum instrument channel width
minimum internal width of an instrument channel (3.8)
Note 1 to entry: See also ISO 8600-6.

3.13
field of view
view of an endoscope (3.1) with optics as stated by the manufacturer or distributor
