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 1402 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 1402:1994), which has been technically revised.

INTERNATIONAL STANDARD ISO 1402:2009(E)
Rubber and plastics hoses and hose assemblies — Hydrostatic
testing
1 Scope
This International Standard specifies methods for the hydrostatic testing of rubber and plastics hoses and
hose assemblies, including methods for the determination of dimensional stability.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 4671, Rubber and plastics hoses and hose assemblies — Methods of measurement of the dimensions of
hoses and the lengths of hose assemblies
ISO 7751, Rubber and plastics hoses and hose assemblies — Ratios of proof and burst pressure to design
working pressure
ISO 8330, Rubber and plastics hoses and hose assemblies — Vocabulary
ISO 23529, Rubber — General procedures for preparing and conditioning test pieces for physical test
methods
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 8330 apply.
4 General
Unless otherwise specified, all tests shall be carried out at standard temperature (see ISO 23529).
5 Apparatus
5.1 Pressure source, capable of applying pressure at the rate specified in 7.2.2, up to the required test
pressure.
5.2 Calibrated pressure gauge or pressure transducer with digital readout, chosen for each test so
that the test pressure is between 15 % and 85 % of the full-scale reading.
In the interest of accuracy, calibrated pressure gauges or pressure transducers with digital readouts shall be
checked at frequent intervals and the fitting of restrictors is recommended to minimize shock damage.
ISO 1402:2009(E)
5.3 Dimensional equipment, sliding vernier callipers or micrometer, length measuring tape, circumferential
measuring tape (π tape).
6 Test pieces
6.1 Hose assemblies
When hose assemblies are to be tested, the manufactured assembly length shall be used for the test.
6.2 Hoses
The hydrostatic pressure and burst tests shall be carried out on a hose test piece with a minimum free length,
excluding end fittings and end reinforcements, of 600 mm when deformation is to be measured and 300 mm
when it is not. When a longer test length is required for a particular hose type or size, it must be specified in
the individual hose product specification.
6.3 Number of test pieces
At least two test pieces shall be tested.
7 Application of hydrostatic pressure
7.1 General
Water or another liquid suitable for the hose under test shall be used as the test medium.
WARNING — Hoses and hose assemblies pressurized by liquids can fail in a potentially dangerous
manner. For this reason, the test shall be performed in a suitable enclosure. Also, the use of air and
other gases as test media shall be avoided because of the risk to operators. In special cases, where
such media are required for the tests, strict safety measures are imperative. Furthermore, it is
stressed that, even when a liquid is used as the test medium, it is essential that all air is expelled from
the test piece because of the risk of injury to the operator due to the sudden expansion of trapped air
released when the hose bursts.
7.2 Procedure
7.2.1 Fill the test piece with test liquid, expelling all air, and connect to the test equipment. Close the valve
and apply the hydrostatic pressure at a uniform rate of increase. Measure the pressure using a calibrated
pressure gauge or pressure t
