National foreword

This British Standard is the UK implementation of EN ISO 4210‑6:2015. It supersedes BS EN ISO 4210‑6:2014 which is withdrawn.

The UK participation in its preparation was entrusted to Technical Committee GME/25, Cycles.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

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.

The committee responsible for this document is ISO/TC 149, Cycles, Subcommittee SC 1, Cycles and major sub-assemblies.

This second edition cancels and replaces the first edition (ISO 4210‑6:2014), which has been technically revised.

ISO 4210 consists of the following parts, under the general title Cycles — Safety requirements for bicycles:

Part 1: Terms and definitions
Part 2: Requirements for city and trekking, young adult, mountain and racing bicycles
Part 3: Common test methods
Part 4: Braking test methods
Part 5: Steering test methods
Part 6: Frame and fork test methods
Part 7: Wheels and rims test methods
Part 8: Pedal and drive system test methods
Part 9: Saddles and seat-post test methods

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 this International Standard 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.

1 Scope

This part of ISO 4210 specifies the frame and fork test methods for ISO 4210‑2.
