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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 5772 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products,
Subcommittee SC 1, Hoses (rubber and plastics).
It cancels and replaces ISO 5772-1:1986, which has been technically revised.
Annexes A and B form an integral part of this International Standard.

INTERNATIONAL STANDARD  ISO ISO 5772:1998(E)
Rubber hoses and hose assemblies for measured fuel
dispensing — Specification
WARNING — Persons using this International Standard should be familiar with normal laboratory practice.
This 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 the requirements for three types of rubber hose and hose assembly used for
measured fuel dispensing, including oxygenated fuels (up to a maximum of 15 % oxygenated compounds).
The three types of hose are as follows:
a) type 1: hoses with textile reinforcement suitable for reeling on a drum or hanging in bends;
b) type 2: hoses with textile and helical wire reinforcement designed for torsional flexibility, suitable for coiling,
reeling on a drum or hanging in bends;
c) type 3: hoses with fine wire reinforcement designed for low dilation, suitable for reeling on a drum or hanging in
bends.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.

3 Materials and construction
The hose shall consist of the following:
 a smooth, fuel-resistant lining of rubber or thermoplastic elastomer (TPE);
 a suitable reinforcement;
 a non-corrugated, fuel- and weather-resistant rubber or TPE cover.
Coupled hose assemblies shall be capable of conducting an electrical charge from coupling to coupling.
When this capability is provided by means of metallic wires, not less than two (crossed) metallic bonding wires shall
be embedded in the hose, and the metal used shall have a high resistance to fatigue, work hardening and
corrosion.
Hoses with metallic wires for electrical conductivity shall be designated "M" and those using conductive compounds
shall be designated "Ω", the relevant mark being branded on the hose (see clause 9).
NOTE Non-reusable corrosion-resistant couplings should preferably be used for this application.
4 Pressure requirements
For all types of hose, the following shall apply:
• maximum working pressure 1,2 MPa (12 bar)
• proof pressure 2,4 MPa (24 bar)
• minimum bursting pressure 4,8 MPa (48 bar)
