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, Rubber and plastics hoses and hose assemblies.
This second edition of ISO 1823 cancels and replaces ISO 1823-1:1997 and ISO 1823-2:1997. Considering
the actual market situations, two classes (the lowest and highest aromatics content) and one grade for
maximum working pressure have been added in 4.3 and 4.4, respectively.
Introduction
This International Standard specifies minimum requirements for the satisfactory performance of
wire- or textile-reinforced rubber hose assemblies of both smooth and rough bore types for oil suction
and discharge services. The hoses are commonly used for transferring crude oil and liquid petroleum
products, other than liquefied petroleum gas and natural gas, to and from tanker and bunkering vessels
or for similar duties ashore.
Specific details of the construction of hoses are not rigidly defined in this International Standard since it
is felt that this could restrict the introduction of improved methods of construction. The hose assemblies
have been classified and designated in terms of service pressure, which includes an allowance for surge
pressure and which equates to the factory test pressure. To keep this specification in line with other
documents, this factory test pressure is also defined as the maximum working pressure (see Table 1). It
is the responsibility of the user to determine the appropriate working pressure, which will depend on the
severity of the user’s operating conditions and on the service life that is expected of the hose assembly.
It is necessary for the purchaser to provide certain information about the hose assembly and its
intended use at the time of enquiry and/or order; this information is listed in Annex A (informative).
Recommendations concerning packaging and transportation are given in Annex B (informative) and
expected masses of hoses, in kilograms per metre of free length, are given in Annex C (informative).

INTERNATIONAL STANDARD ISO 1823:2015(E)
Rubber hose and hose assemblies for oil suction and
discharge service — Specification
1 Scope
This International Standard specifies the characteristics of four types of oil suction and discharge
hose assemblies used for the conveyance of petroleum, including crude oils and other liquid petroleum
products. Each type being divided into three classes depend on the aromatic contents. It is not suitable
for liquefied petroleum gas and natural gas.
