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. www .iso .org/ directives

Introduction

The purpose of this International Standard is to ensure the safe operation of vehicles. The wheel is a

highly stressed component of the vehicle that may be subject in service to extreme forces. Therefore, it is

absolutely necessary to handle these parts with care and to pay particular attention to their mounting,

removal and maintenance in order to ensure safe operations and to prevent servicing accidents.

DRAFT INTERNATIONAL STANDARD ISO/DIS 14400:2021(E)
Road vehicles — Wheels and rims — Use, general
maintenance and safety requirements and out-of-service
conditions
1 Scope

This International Standard specifies requirements for the use, and general maintenance and safety

of wheels and rims including multi-piece wheels and rims. and defines their out-of-service conditions,

such as cracked, worn and bent wheels and rim components. It is applicable to wheels intended for

use on road as defined in ISO 3833 and off road vehicles. This standard does not include mopeds and

motorcycles.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

ISO 3833, Road vehicles — Types — Terms and definitions

ISO 3911, Wheels and rims for pneumatic tyres — Vocabulary, designation and marking

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 3911 apply

4 Use and general maintenance requirements

WARNING — On multi-piece rims, the use of the wrong ring components can result in catastrophic

wheel failure.
4.1 Wheel and wheel components

Wheels or parts of wheels which cannot be identified shall not be used even if they seem to have the

correct functions and the identical dimensions. The characteristics of the wheel centre shall exactly

correspond to vehicle parts, especially the axle hub and the brake, in order to guarantee a proper fitting

and an effective load transmission.

A neutral non-aggressive mounting paste or liquid shall be used to lubricate the tyre beads. The hub,

studs, nuts and the wheel attachment face shall be carefully cleaned. In the case of multi-piece wheels,

all contact surfaces shall be cleaned.

Inspect parts for out-of-service conditions, see Clause 6. If cleaning does not restore the original

condition for the mating surfaces or if the parts have any of the conditions described in Clause 6, the

parts shall be replaced.
4.2 Wheel mounting and removal

Mounting and removal of wheels shall be carried out by trained personnel only. Only the correct tools

shall be used to carry out the various operations.

ISO/DIS 14400:2021(E)

On multi-piece rims, prior to inflation of the tyre, the correct positioning of the lock ring, the loose

flange ring and rubber O-rings, or sealing rings if applicable, shall be carefully checked, always avoiding

any correction by means of a hammer. In the case of incorrect positioning, all the air shall be let out of

tyre and the whole mounting procedure repeated.

When inflating tyres, the wheel shall be placed in a safety cage or else safety chains shall be put round

the wheel. The operator shall not stay in the near dangerous areas or trajectories. Trajectory means

any potential path or route that a rim wheel component can travel during an explosive separa
