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 121, Anaesthetic and respiratory equipment,
Subcommittee SC 1, Breathing attachments and anaesthetic machines.
This fourth edition cancels and replaces the third edition (ISO 5356-1:2004), which has been technically
revised with the following changes:
— harmonizing the terminology used in the text with the title of this part of ISO 5356;
— deleting the definition of 22 mm latching connector because the content is covered by the text of this
part of ISO 5356;
— including 11,5 mm cones and sockets;
— adding the minimum internal diameter for the 30 mm cone and changing the minimum internal
diameter of the 8,5 mm cone from 6,0 mm to 6,25 mm;
— deleting the requirements on reuse of 22 mm latching sockets and cones because this is covered by
the standards for the specific medical devices and accessories;
— making the recess and the shoulder for the 22 mm cone conditional;
— correcting the dimension D for the plug and ring test gauges for 8,5 mm cones and sockets made of
materials other than metal in Annex A of this part of ISO 5356;
— restructuring the document for clarity.
ISO 5356 consists of the following parts, under the general title Anaesthetic and respiratory equipment —
Conical connectors:
— Part 1: Cones and sockets
— Part 2: Screw-threaded weight-bearing connectors

Introduction
In clinical practice, several breathing attachments used in anaesthetic and respiratory equipment may
have to be joined together to provide a suitable breathing system. Items of medical equipment, such as a
humidifier or a spirometer, are often incorporated into the breathing system which might also be connected
to an anaesthetic gas scavenging system. Connections for these purposes are usually cone and socket joints,
and a lack of standardization of these connections has given rise to problems of interchangeability when
connecting equipment made by different manufacturers. This part of ISO 5356 specifies the requirements
and dimensions for cones and sockets used in anaesthetic and respiratory equipment.
An important consideration is that conical connections need to be secure but nevertheless disconnectable
by the operator. The use of cones and sockets meeting the requirements of this part of ISO 5356 will not
necessarily prevent them being disconnected accidentally. To minimize the risk of 22 mm connectors
being accidentally disconnected, latching sockets can be used.
Annex A includes a figure and a table detailing plug and ring test gauges that are used to check cones
and sockets made of materials other than metal. Annex B, Annex C, and Annex D provide test methods
for latching sockets, Annex E includes a figure and table detailing plug and ring test gauges that can be
used to check metal cones and sockets, and Annex F contains recommendations for testing the security
of latching sockets.
Figure 1, detailing the dimensions and tolerances of cones and sockets, has been prepared in accordance
with ISO 3040.
In this document, the following print types are used:
— requirements, compliance with which can be verified, and definitions: roman type;
— notes and examples: smaller roman type;
— test methods: italic type.

INTERNATIONAL STANDARD ISO 5356-1:2015(E)
Anaesthetic and respiratory equipment — Conical
connectors —
Part 1:
Cones and sockets
1 Scope
This part of ISO 5356 specifies dimensional and gauging requirements for cones and sockets intended
for connecting anaesthetic and respiratory equipment, e.g. in breathing systems, anaesthetic gas
scavenging systems, and vaporizers. The cones and sockets are therefore not regarded as devices in
their own right.
This part of ISO 5356 gives requirements for the following cones and sockets:
— 8,5 mm and 11,5 mm sizes intended for use in neonatal and paediatric breathing systems;
— 15 mm and 22 mm sizes intended for general use in breathing systems;
— 22 mm latching sockets (including performance requirements);
— 23 mm size intended for use with vaporizers, but not for use in breathing systems;
— 30 mm size intended for the connection of a breathing system to an anaesthetic gas scavenging system.
This part of ISO 5356 does not specify the medical devices and accessories on which these cones and
sockets are to be provided.
Requirements for the application of cones and sockets are not included in this part of ISO 5356, but are
or will be given in the relevant International Standards for specific medical devices and accessories.
NOTE Requirements for screw-threaded weight-bearing connectors are specified in ISO 5356-2.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
