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 8031 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
This third edition cancels and replaces the second edition (ISO 8031:1993), which has been technically
revised (for details, see the Introduction).

Introduction
This edition of ISO 8031 addresses the problems encountered in field testing and during product acceptance
tests in a production facility in following the test procedures specified in the previous edition (ISO 8031:1993)
and a more practical approach is suggested. Also, a test procedure for determining electrical continuity
between the end fittings of a hose assembly without actually measuring the resistance has been introduced.
This test is frequently carried out in the field and in the factory when the product standard does not require the
exact electrical resistance to be measured, but only requires verification of electric conductivity between both
metal end fittings.
Special test methods to determine the electrical resistance through the hose wall (now required in some
product standards for hoses used in explosive atmospheres) have been added.
Some test methods which have been standard practice in the hose industry for some time have now been
included, as have several new methods to determine the ability of a hose assembly (with metal end fittings) to
dissipate static electric charges when the metal end fitting is connected to earth. A total of four new
explanatory sketches are included. The hose and hose assembly product standard applicable will have to
specify which method is most suitable for the purpose of verification of the required property.
Annex A, an amended version of informative Annex A, “Recommended terminology and limits for electrical
resistance”, in ISO 8330:2007, has been included.
