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 45, Rubber and rubber products, Subcommittee SC 1,
Hoses (rubber and plastics).
This third edition cancels and replaces the second edition (ISO 6806:1992), of which it constitutes a
minor revision.
The following changes (mainly editorial) were made as required to bring the standard up to date.
— Clause 2 (Normative references) has been updated where necessary. Reference to ISO 4672 has been
replaced by ISO 10619-2 and the new titles of ISO 1307, ISO 1436 and ISO 4671 have been quoted.
— Wherever necessary the terminology has been amended to conform to ISO 8330.
— New Clause 7 (Frequency of testing) and Clause 8 (Type tests) have been introduced; new Annexes A
and B (Tables A.1 and B.1) have been introduced to standardize the frequency of the tests already
required in the previous edition (ISO 6806:1992).
— Clause 9 (Marking) has been amended (maximum working pressure and date of publication of this
International Standard to be marked on hose).
— No technical changes from requirements already specified in the second edition (ISO 6806:1992)
have been made.
