ISO 10542-5:2004

Technical systems and aids for disabled or handicapped persons — Wheelchair tiedown and occupant-restraint systems — Part 5: Systems for specific wheelchairs

ISO 10542-5:2004 specifies test methods as well as requirements for design and performance, for instructions and warnings to installers and users, and for product marking and labelling of wheelchair tiedown and occupant restraint systems (WTORS). It applies only to WTORS that are intended to be used with particular makes and models of wheelchairs when used as a forward-facing seat by a passenger or a driver of a motor vehicle. ISO 10542-5:2004 applies to WTORS intended for use with manual or powered wheelchairs, including scooters with three or more wheels, intended for use by children or adults of mass equal to or greater than 22 kg. ISO 10542-5:2004 applies primarily to complete WTORS, but parts of this International Standard can also be applied to components and sub-assemblies sold separately and for replacement parts.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 10542-5 was prepared by Technical Committee ISO/TC 173, Technical systems and aids for disabled or
handicapped persons, Subcommittee SC 1, Wheelchairs.
ISO 10542 consists of the following parts, under the general title Technical systems and aids for disabled or
handicapped persons — Wheelchair tiedown and occupant-restraint systems:
— Part 1: Requirements and test methods for all systems
— Part 2: Four-point strap-type tiedown systems
— Part 3: Docking-type tiedown systems
— Part 4: Clamping tiedown systems
— Part 5: Systems for specific wheelchairs

ISO 10542-5:2004(E)
Introduction
Providing effective crash protection for wheelchair-seated occupants of motor vehicles generally requires the
installation and use of equipment to tie down the wheelchair and restrain the occupant of the wheelchair.
ISO 10542-1 establishes general requirements and test methods for wheelchair tiedown and occupant restraint
systems (WTORS) that are designed for use with a wide range of wheelchairs and adult occupants. This part of
ISO 10542 establishes additional or alternative requirements for WTORS that are intended to be used with
specific makes and models of wheelchairs. The belt-type occupant restraints may attach to the wheelchair such
that occupant-restraint loads will be transferred through the wheelchair. This part of ISO 10542 applies to
WTORS intended for use with children whose mass is greater than 22 kg, in addition to WTORS intended for
use by adults. Children whose mass is less than 22 kg should be transferred from their wheelchairs into
appropriate child restraint systems intended for use in vehicles.
The provisions of ISO 10542-1 apply except as amended and supplemented by this part of ISO 10542.
ISO 10542-1 and this part of ISO 10542 place particular emphasis on design requirements, performance
requirements, and associated test methods with regard to the performance of WTORS for forward-facing
wheelchairs and occupants in frontal impacts. Because this part of ISO 10542 addresses WTORS intended for
use with specific makes and models of wheelchairs, the 48-km/h frontal impact test is conducted with a specific
make or model of wheelchair, rather than with a surrogate wheelchair specified in ISO 10542-1. As such, the
performance of both the WTORS and wheelchair are evaluated as a total system.
Transportation-related requirements for wheelchairs that are suitable for adult occupant seating during motor
vehicle transportation are specified in ISO 7176-19.
