ISO 4210-7:2023(E)
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

ISO 4210-7:2023(E)
This document has been developed in response to demand throughout the world, and the aim has been
to ensure that bicycles manufactured in conformity with this document 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
If the bicycle should be used on public roads, national regulations apply.

4 Test methods
4.1 Wheel and tyre assembly — Rotational accuracy
The run-out tolerances represent the maximum variation of the position of the rim when measured
perpendicular to the axle at a suitable point along the rim (see Figure 1 and Figure 2) (i.e. full indicator
reading) of a fully assembled and adjusted wheel during one complete revolution about the axle without
axial movement. Both sides of the rim shall be measured and the maximum value shall be taken as
For city and trekking, mountain, and young adult bicycles, the measurement of both axial run-out
(lateral) and radial run-out (concentricity) shall be done with a tyre fitted and inflated to the maximum
inflation pressure, but for rims where concentricity c
