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

Introduction
This International Standard has been developed to provide guidelines on the quality and performance of
all floating pneumatic rubber fenders. Floating pneumatic rubber fenders can play an important role in a
ships safe berthing operation and this International Standard is seen as a technical reference to ensure
necessary product standards.
Essentially there are two main types of floating pneumatic rubber fender, defined as either high- or
low-pressure fenders. Although manufactured using different techniques, both high and low-pressure
fenders work by the same principle. The resistance to berthing vessel momentum is provided by a
reaction pressure due to compression of the air inside the fender when deformed by the vessels hull. The
kinetic energy of the berthing vessel is absorbed during the work done to compress the air inside the
fender. Fenders are sized according to the expected duty of the fender in terms of the energy absorption
(EA) requirements which will be at the most basic level, a function of the vessel mass and velocity.
Throughout this International Standard, the minimum essential criteria are identified by the use of
the key word “shall”. Recommended criteria are identified by the use of the key word “should”, and
while not mandatory are considered to be of primary importance in providing serviceable, economical
and practical connectors. Deviation from the recommended criteria should occur only after careful
consideration, extensive testing and thorough service evaluation have shown alternative methods to be
satisfactory.
The documents in the Bibliography provide information on the usage of the fenders.

ISO 17357-2:2014(E)

3.1
bead ring
ring of several layers of high-tensile steel wire which is an integral part of moulded ends, reinforcing the
end around which the end closure plate assembly is clamped
3.2
clamped end fitting
metal assembly comprising of end link plates and mooring plates, fitted to the ends of the clamped end
fenders to seal the ends of the fender and also to provide mooring points
3.3
clamped end type
low-pressure fenders up to and including 2,3 m diameter, manufactured from a number of longitudinal
panels of coated textile and sealed by means of clamped end fittings
Note 1 to entry: Typically the longitudinal panels are tapered at the ends to form a parabolic shape, though for
smaller fenders the ends can be folded to form a “parcel end” design.
3.4
coated textile
vulcanized-synthetic-rubber-covered high-tenacity continuous filament woven nylon textile
Note 1 to entry: The outer coating is designed to give a high level of resistance to abrasion and other external
forces. The combination of the inner and outer synthetic rubber coating provides the required resistance of
permeability to the escape of the compressed air essential for the demands of the product.
3.5
end closure plate assembly
metal assembly fitted to the low-pressure moulded end fenders to close off both ends of the fender and,
in addition, at one end, the inflation air valve and pressure gauge valve are fitted
Note 1 to entry: The mooring fittings are attached to this assembly.
3.6
guaranteed energy absorption
energy the fender can absorb without permanent deformation or failure
3.7
initial internal pressure
air pressure at which an uncompressed fender operates, i.e. the initial pressure to which a fender is
inflated
3.8
low-pressure floating pneumatic rubber fender
fender which is manufactured essentially from a textile reinforced rubber material with compressed air
inside, at a typical initial pressure of 7 kPa, to enable it to float on the water and act as a shock absorber
between ship and ship or between ship and berthing structures when they are coming alongside each
other on the water
3.9
moulded end type
low-pressure fenders of 2,8 m diameter and above, which are manufactured with a cylindrical body
fabricated from a number of longitudinal panels of coated textile, onto which are attached hemispherical-
shaped moulded sections at each end
3.10
reaction force
force produced by a fender reacting to a compressive force
Note 1 to entry: Reaction force is equal to the force of the air pressure of the fender multiplied by the contact area
of the fender to the ship or berthing structure.

c) initial internal pressure (see 4.2);
d) fender size: nominal fender diameter and length (see Tables 1, 2, or 3);
NOTE If the purchaser requests other sizes, they shall satisfy the requirements of 6.3.
e) fender colour (if not specified, the colour shall be black);
f) if inspection/evaluation by a major classification is required, see Clause 12.

This certificate confirms successful results of the tests in Clause 8, which are evaluated by a major
classification society and are conducted no more than 10 years prior to inquiry date.
b) Commercial fender inspection and test certificate
This certificate confirms successful results of the inspections and the tests in Clause 9, which shall be
performed on fenders which have a diameter equal to or larger than the inquired fender with the same
or higher internal pressure, and are evaluated by a major classification society and are conducted no
more than 10 years prior to inquiry date.
