Rubber and plastic hoses and hose assemblies for measured fuel dispensing systems — Specification
ISO 5772:2015 specifies minimum requirements for three types of hoses in two categories and two classes of hose assemblies used for measured fuel dispensing, including oxygenated fuels (up to a maximum of 15 % oxygenated compounds). The assemblies are intended for use at ambient temperatures between −30 °C and +55 °C for normal temperature class and −40 °C and +55 °C for low temperature class at a working pressure up to and including 16 bar (1,6 MPa). NOTE 1 bar = 0,1 MPa.

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 cancels and replaces the first edition (ISO 5772:1998), which has been technically
revised to include the following changes:
— working pressure is 16 bar (1,6 MPa) instead of 12 bar (1,2 MPa) but proof pressure and burst
pressure remain the same;
— minimum tensile strength of lining and cover has been increased from 7 MPa to 9 MPa;
— extraction of the lining for low temp hoses has been added and the Low Temperature Bending test
is to be done at 25 °C with the force to bend specified;
— hose fuel permeation, flammability, assembly flex test, and assembly leak test have been added.
All the annexes form an integral part of this International Standard.

INTERNATIONAL STANDARD ISO 5772:2015(E)
Rubber and plastic hoses and hose assemblies for
measured fuel dispensing systems — Specification
WARNING — Persons using this International Standard should be familiar with normal
laboratory practice. This International Standard does not purport to address all of the
safety problems, if any, associated with its use. It is the responsibility of the user to establish
appropriate safety and health practices and to ensure compliance with any national regulatory
conditions.
1 Scope
This International Standard specifies minimum requirements for three types of hoses in two categories
and two classes of hose assemblies used for measured fuel dispensing, including oxygenated fuels (up
to a maximum of 15 % oxygenated compounds).
The assemblies are intended for use at ambient temperatures between −30 °C and +55 °C for normal
temperature class and −40 °C and +55 °C for low temperature class at a working pressure up to and
including 16 bar (1,6 MPa).
NOTE 1 bar = 0,1 MPa.
