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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 4641 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
This fourth edition cancels and replaces the third edition (ISO 4641:2005), which has been technically revised.
The following changes have been made:
⎯ the pressures in megapascals have been introduced in the tables and text next to the pressures given in
bars;
⎯ modifications have been made to the wording used in Clause 9 and in Annexes A and B.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 8330 apply.
4 Classification
Hoses and hose assemblies for this application are classified into three types according to their operating duty
requirements:
⎯ Type 1: Light-duty hoses for suction service to −0,063 MPa (−0,63 bar) and for discharge pressures up to
0,3 MPa (3 bar).
⎯ Type 2: Medium-duty hoses for suction service to −0,08 MPa (−0,8 bar) and for discharge pressures up to
0,5 MPa (5 bar).
⎯ Type 3: Heavy-duty hoses for suction service to −0,097 MPa (−0,97 bar) and for discharge pressures up
to 1,0 MPa (10 bar).
5 Couplings and end fittings
Hoses shall be fitted with end fittings/couplings to form hose assemblies. Annex C lists types of coupling and
end fitting.
6 Materials and construction
6.1 Lining
The lining shall consist of suitably compounded water-resistant natural or synthetic rubber. Its internal surface
shall be smooth and free from imperfections which could impair the expected use.
6.2 Reinforcement
The reinforcement shall consist of a suitable textile material and may contain a helix that can be metallic wire
or of another suitable material.
6.3 Cover
The cover shall consist of suitably compounded natural
