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.

4.5 Crack detection methods

Standardised methods should be used to emphasize the presence of cracks where visible cracks are

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.
4.7 Brakes
4.7.1 Braking-systems
