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 World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Rubber and plastics hoses and hose assemblies.
This fifth edition cancels and replaces the fourth edition (ISO 4641:2010), of which it constitutes a
minor revision with the following changes:
— Clause 2 has been updated, where ISO 1746 and ISO 4672 have been deleted and replaced by
ISO 10619-1 and ISO 10619-2, respectively;
— tolerance dimension “in mm” has been added to 7.1;
— the text of 8.2.3, 8.2.5, 10.1 and 10.2 has been slightly modified to bring the references up to date;
— Table 4 has been slightly modified to bring the references up to date;
— Bibliography has been updated as ISO 10619-1 and ISO 10619-2 are now published and listed in
Clause 2.
— the text has been editorially revised to comply with the most recent editing rules.
