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).

5 Materials and construction
5.1 Hoses
Type 1 hose assemblies shall consist of an abrasion-resistant rubber lining, one or more layers of steel
or textile reinforcement, a textile-reinforced rubber undercover, a flexible closed-cell flotation material
integrally fitted round the hose body as described in 5.2, an abrasion- and weather-resistant rubber or
thermoplastic outer cover (which, in the case of a rubber cover, can include one or two textile breaker layers),
and end fittings as described in 5.3 on both ends.
Type 2 hose assemblies shall consist of an abrasion-resistant rubber lining, one or more layers of steel or
textile reinforcement, a textile-reinforced rubber, full rubber or thermoplastic cover at least 6 mm thick for
hoses of nominal size less than 500, at least 10 mm thick for hoses of nominal size in the range from 500 to
850 inclusive and at least 12 mm thick for hoses of nominal size in the range from 900 to 1 300 inclusive, and
end fittings as described in 5.3 on both ends. The lining thickness shall be at least 8 mm for nominal sizes up
to and including 200, at least 10 mm for nominal sizes 250 to 500 inclusive, at least 12 mm for nominal sizes
550 to 800 inclusive and at least 16 mm for nominal sizes 850 to 1 300 inclusive.

oSIST prEN ISO 28017:2025
ISO/DIS 28017:2025(en)
5.2 Flotation material
The closed-cell flotation material used in type 1 hose assemblies shall adhere firmly both to the hose body
and to the outer cover so that it cannot move or tend to become detached in service. At the ends of the hose, a
space shall be provided to facilitate the insertion of connection bolts and to allow the use of mechanical tools
for tightening nuts on the bolts. The flotation material shall be distributed over the whole length of the hose
assembly in such a manner that the hose assembly floats evenly when connected to other assemblies in a string.
This does not apply to hose assemblies for special applications (e.g. the end of a string, tapered hose, etc.).
5.3 End fittings and end connections
End fittings shall be mechanically and chemically bonded to the hose body. With hoses intended for delivery
use only, clamped-on and swaged-on nipples are not acceptable, but such nipples may be utilized with hoses
intended for suction use. Alternatively, flanged end connections built up of hose reinforcement, lining and
cover material are acceptable provided they are additionally reinforced by steel stiffening rings to avoid
distortion when the connection bolts are tightened. All hose assemblies shall be fitted with either end
fittings or flanged end connections unless otherwise required by the end user.
6 Dimension and tolerances
6.1 Diameters
The test shall be carried out in accordance with ISO 4671. The inside diameters of hoses shall conform to the
values given in Table 4.
The test shall be carried out in accordance with ISO 4671. The outside diameters of hoses shall conform to
the values specified by the customer.
NOTE For hoses manufactured on mandrels with diameters in inches, the tolerances on the inside diameter
are the same as those given for hoses with diameters in metric units in Table 4 (i.e. ±3 mm for sizes 4 in to 8 in
inclusive, ±4 mm for 10 in to 12 in inclusive, ±5 mm for 14 in to 30 in inclusive, ±6 mm for 32 in to 40 in inclusive
and ±7 mm for 44 in and 48 in).
