Full title and description

ISO 10542-4:2004 — Technical systems and aids for disabled or handicapped persons — Wheelchair tiedown and occupant-restraint systems — Part 4: Clamp-type tiedown systems. This part of ISO 10542 defines design, performance, marking and information requirements specifically for clamp-type tiedown wheelchair tiedown and occupant-restraint systems (WTORS) used to secure wheelchairs when used as forward-facing seats in motor vehicles.

Abstract

ISO 10542-4:2004 specifies test methods and requirements for design and performance, installer and user instructions, and product marking and labelling of WTORS that use clamp-type tiedowns. It applies primarily to complete clamp-type WTORS and — where relevant — to components and replacement parts, for use with manual and powered wheelchairs (including multi-wheeled scooters). The standard includes performance requirements, test report provisions and an annex addressing frontal impact testing and design guidance.

Scope

This part of ISO 10542 applies only to WTORS that use clamp-type tiedowns to secure wheelchairs used as forward-facing seats by adult passengers or drivers in motor vehicles. It is intended primarily for complete WTORS but can be applied in part to components, sub-assemblies and replacement parts. The scope covers design and performance requirements, instructions for installers and users, marking and labelling, and specified test methods (including frontal impact testing in an annex).

Key topics and requirements

• Design requirements for clamp-type tiedown hardware and attachment geometry.
• Performance requirements and acceptance criteria for tiedown strength and retention under specified loads and dynamic tests.
• Test methods including dynamic impact (frontal impact) procedures and test-reporting requirements.
• Information, identification and instruction requirements for installers, users and vehicle modifiers (marking and labelling, user instructions).
• Applicability criteria for different wheelchair types (manual, powered, scooters with three or more wheels) and for components versus complete systems.
• Normative references, terms and definitions specific to wheelchair tiedown and occupant-restraint systems.

These key topics are drawn from the standard's clauses and annex structure as published.

Typical use and users

Manufacturers of wheelchair tiedown and occupant-restraint systems, vehicle converters and mobility vehicle manufacturers, independent testing laboratories, certification bodies, procurement specialists for ambulances and public transport, and disability service providers use this standard to design, test, specify, install and evaluate clamp-type WTORS. Regulators and vehicle modifiers consult it for compliance guidance and to harmonize safety requirements for wheelchair passenger restraint.

Related standards

ISO 10542-4:2004 is part of the ISO 10542 series addressing WTORS. The part was withdrawn and its provisions were incorporated into later consolidated editions of the ISO 10542 series (notably ISO 10542-1:2012 and subsequent consolidated revisions/AMs in national adoptions). Other related standards include adjacent parts of ISO 10542 (parts addressing different tiedown system types and specific wheelchair systems) and vehicle/occupant-restraint or wheelchair seating standards such as those in the ISO 16840 and related motor-vehicle restraint standards.

FAQ

Q: What is this standard?

A: ISO 10542-4:2004 is an international standard that provided requirements and test methods for clamp-type wheelchair tiedown and occupant-restraint systems used to secure wheelchairs in forward-facing seating positions in motor vehicles.

Q: What does it cover?

A: It covered design and performance requirements, test methods (including dynamic/frontal impact testing), information and instruction requirements for installers and users, product marking and labelling, and test-report content for clamp-type WTORS and applicable components.

Q: Who typically uses it?

A: Manufacturers of tiedown systems and components, testing laboratories, vehicle modifiers, ambulance and transit equipment specifiers, safety and compliance officers, and standards/approval bodies. These users rely on the standard for design, testing and procurement specifications.

Q: Is it current or superseded?

A: ISO 10542-4:2004 has been withdrawn and its content consolidated into later revisions of the ISO 10542 series (notably ISO 10542-1:2012 and subsequent consolidated national/adopted versions). Users should reference the current ISO 10542 series documents (and any national adoptions/amendments) for up-to-date requirements.

Q: Is it part of a series?

A: Yes. ISO 10542 is a multipart series addressing wheelchair tiedown and occupant-restraint systems; Part 4 addressed clamp-type tiedown systems. Other parts cover different system types and specific wheelchair/system configurations.

Q: What are the key keywords?

A: wheelchair tiedown, clamp-type tiedown, WTORS, occupant restraint, ISO 10542, test methods, frontal impact, marking, installer instructions.
