Introduction
This International Standard has been developed in response to demand throughout the world, and the
aim has been to ensure that bicycles manufactured in compliance with it will be as safe as is practically
possible. The tests have been designed to ensure the strength and durability of individual parts as well
as of the bicycle as a whole, demanding high quality throughout and consideration of safety aspects from
the design stage onwards.
The scope has been limited to safety considerations, and has specifically avoided standardization of
components.
If the bicycle is to be used on public roads, national regulations apply.
For safety requirements for toy bicycles intended for very young children see national regulations and
standards.

4 Requirements and test methods
4.1 Brake tests and strength tests — Special requirements
4.1.1 Definition of brake tests
Brake tests to which accuracy requirements apply, as in 4.1.4, are those specified in 4.7.2.3 to 4.7.8.4
inclusive.
4.1.2 Definition of strength tests
Strength tests to which accuracy requirements apply, as in 4.1.4, are those involving static, impact or
fatigue loading as specified in 4.8 to 4.14 inclusive and 4.16.
4.1.3 Numbers and condition of specimens for the strength tests
In general, for static, impact and fatigue tests, each test shall be conducted on a new test sample, but
if only one sample is available, it is permissible to conduct all of the tests on the same sample with the
sequence of testing being fatigue, static and impact.
When more than one test is conducted on the same sample, the test sequence shall be clearly recorded
in the test report or record of testing.
NOTE It should be noted that if more than one test is conducted on the same sample, earlier test can influence
the results of subsequent tests. Also, if a sample fails when it has been subjected to more than one test, a direct
comparison with single testing is not possible.
In all strength tests, specimens shall be in the fully finished condition.
It is permitted to carry out tests with dummy assemblies such as a fork or handlebar when carrying out
frame or handlebar stem tests.
4.1.4 Tolerances
Unless stated otherwise, accuracy tolerances based on the nominal values shall be as follows:
— Forces and torques: 0/+5 %
— Masses and weights: ±1 %
— Dimensions: ±1 mm
— Angles: ±1°
— Time duration: ±5 s
— Temperatures: ±2 °C
— Pressures: ±5 %
4.1.5 Fatigue test
The force for fatigue tests is to be applied and released progressively, not to exceed 10 Hz. The tightness
of fasteners according to manufacturer’s recommended torque can be re-checked not later than 1 000
test cycles to allow for the initial settling of the component assembly. (This is considered applicable to
all components, where fasteners are present for clamping.) The test bench shall be qualified to meet
dynamic requirements of 4.1.4.

specified as criteria of failure in tests specified in this International Standard.
[2][3][4][5]
NOTE For example, suitable dye-penetrant methods are specified in ISO 3452 (all parts) .
4.6 Protrusions
These requirements are intended to address the hazards associated with the users of bicycles falling on
projections or rigid components (e.g. handlebars, levers) on a bicycle possibly causing internal injury or
skin puncture.
Tubes and rigid components in the form of projections which constitute a puncture hazard to the rider
should be protected. The size and shape of the end protection has not been stipulated, but an adequate
shape shall be given to avoid puncturing of the body. Screw threads which constitute a puncture hazard
shall be limited to a protrusion length of one major diameter of the screw beyond the internally threaded
mating part.

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 8098 was prepared by Technical Committee ISO/TC 149, Cycles, Subcommittee SC 1, Cycles and major
sub-assemblies.
This third edition cancels and replaces the second edition (ISO 8098:2002), of which has been technically
revised.

Introduction
Safety requirements for bicycles intended to be ridden on public roads by adults and children aged about eight
years and older (i.e. bicycles having saddle heights of 635 mm and above) are given in ISO 4210.
While ISO 8098 follows the lines of ISO 4210, it covers requirements for bicycles suitable for young children
aged from about four to eight years. These bicycles are not intended to be ridden on public roads and should
not be presumed to be suitably equipped for that purpose.
For safety requirements for toy bicycles intended for very young children see EN 71-1.

4 Requirements and test methods
4.1 Brake tests and strength tests – special requirements
4.1.1 Definition of brake tests
Brake tests to which accuracy requirements apply, as in 4.1.4, are those specified in 4.7.2.2.3 to 4.7.8.4
inclusive.
4.1.2 Definition of strength tests
Strength tests to which accuracy requirements apply, as in 4.1.4, are those involving static, impact or fatigue
loading as specified in 4.8 to 4.14 inclusive and 4.16.
4.1.3 Numbers and condition of specimens for the strength tests
In general, for static, impact and fatigue tests, each test shall be conducted on a new test sample, but if only
one sample is available, it is permissible to conduct all of the tests on the same sample with the sequence of
testing being fatigue, static and impact.
When more than one test is conducted on the same sample, the test sequence shall be clearly recorded in the
test report or record of testing.
During fatigue testing, the forces shall be applied and released progressively.
NOTE It should be noted that if more than one test is conducted on the same sample, earlier test can influence the
results of subsequent tests. Also, if a sample fails when it has been subjected to more than one test, a direct comparison
with single testing is not possible.
In all strength tests, specimens shall be in the fully finished condition.
It is permitted to carry out tests with dummy assemblies such as a fork or handlebar when carrying out frame
or handlebar stem tests.
4.1.4 Accuracy tolerances of test conditions for brake tests and strength tests
4.1.4.1 Tolerances
Unless stated otherwise, accuracy tolerances based on the nominal values shall be as follows:
⎯ Forces and torques 0/+5 %
⎯ Masses and weights ± 1 %
⎯ Dimensions ± 1 mm
⎯ Angles ± 1°
⎯ Time duration ± 5 s
⎯ Temperatures ± 2 °C
⎯ Pressures ± 5 %
