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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT), see the following URL: Foreword — Supplementary information.
The committee responsible for this document is ISO/TC 149, Cycles, SC 1, Cycles and sub-assemblies.
ISO 6742 consists of the following parts, under the general title Cycles — Lighting and retro-reflective devices:
— Part 1: Lighting and light signalling devices
— Part 2: Retro reflective devices
— Part 3: Installation and use of lighting and retro-reflective devices
— Part 4: Lighting systems powered by the cycle’s movement
— Part 5: Lighting systems not powered by the cycle’s movement

ISO 6742-3:2015(E)

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 test method with PSD (6.1.2.2) reflects today’s state of the art and should be preferred to the sine
sweep vibration test (6.1.2.3).
Users of the standard are invited to provide their feedback to ISO/TC 149/SC 1.
