Full title and description

Technical systems and aids for disabled or handicapped persons — Wheelchair tiedown and occupant-restraint systems — Part 1: Requirements and test methods for all systems (ISO 10542-1:2012). This Part specifies design and performance requirements, associated test methods, product marking and labelling, and manufacturers' instructions and warnings for wheelchair tiedown and occupant‑restraint systems (WTORS) that use belt‑type occupant restraints for forward‑facing wheelchair seating in motor vehicles.

Abstract

ISO 10542-1:2012 sets minimum design, performance and test requirements for WTORS intended for occupied manual and powered wheelchairs (including three‑ and four‑wheeled scooters) used as forward‑facing seats by passengers and drivers in motor vehicles. The standard covers complete systems and applicable components, requires belt‑type occupant restraints (pelvic and upper‑torso), defines dynamic crash test conditions and includes requirements for product marking, labelling and user/installer information.

General information

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 11.180.10 (Aids and adaptations for moving).
• Edition / version: Edition 2 (2012); amended (ISO 10542-1:2012/Amd 1:2021) and corrigendum issued in 2013.
• Number of pages: 68 pages.

Scope

This part of ISO 10542 applies to WTORS that use belt‑type occupant restraints and are intended for forward‑facing occupied wheelchairs in motor vehicles. It is applicable to systems for manual and powered wheelchairs and scooters used by persons with body mass of 22 kg or greater, and can be applied to complete systems as well as relevant components and replacement parts. The standard’s primary purpose is to reduce the risk of injury to wheelchair‑seated occupants in frontal collisions by specifying design, performance and crash test requirements and by ensuring appropriate marking and user/installer information.

Key topics and requirements

• Design requirements for WTORS components (tiedown hardware, securement adaptors, anchorages, and belt‑type occupant restraints).
• Performance requirements including dynamic frontal crash testing (nominal 48 km/h, 20 g frontal sled test using an 85 kg surrogate wheelchair and an anthropomorphic test device to evaluate system performance).
• Requirements that WTORS include both pelvic and upper‑torso belt restraints and criteria for webbing, anchorage strength and partial‑engagement behaviour.
• Test methods and normative annexes covering frontal impact procedures, surrogate wheelchair specifications, belt geometry and webbing slippage tests.
• Product marking, labelling, manufacturer instructions and installer/user warnings to ensure correct selection, installation and use.

Typical use and users

Used by WTORS manufacturers for product design and testing, wheelchair and docking‑device designers for compatibility, vehicle converters and mobility vehicle OEMs for installation and certification, transit operators and fleet managers for procurement and compliance, and test laboratories and certification bodies that perform dynamic crashworthiness testing and conformity assessment.

Related standards

ISO 10542-1:2012 consolidates and supersedes earlier part‑specific documents (formerly ISO 10542‑2, ‑3, ‑4 and ‑5). It is used alongside wheelchair and vehicle seating standards such as ISO 7176‑19 (wheelchairs for use as vehicle seats) and complementary vehicle/wheelchair containment standards (for example ISO 10865 series). Normative references include vehicle restraint and test standards such as ECE R16 and FMVSS 209 that are cited within the text. The 2012 edition has a Corrigendum (2013) and an Amendment 1 (2021) covering additional annex material.

FAQ

Q: What is this standard?

A: ISO 10542-1:2012 is an international standard that specifies requirements and test methods for wheelchair tiedown and occupant‑restraint systems (WTORS) intended for forward‑facing wheelchair seating in motor vehicles.

Q: What does it cover?

A: It covers design and performance criteria, dynamic frontal crash testing protocols, marking and labelling, and manufacturer instructions and warnings for belt‑type occupant restraints and tiedown systems for wheelchairs and scooters (for users ≥ 22 kg).

Q: Who typically uses it?

A: Manufacturers of WTORS and components, wheelchair and docking‑device designers, vehicle converters and mobility OEMs, transit operators and fleet managers, test laboratories and conformity assessment bodies.

Q: Is it current or superseded?

A: The 2012 second edition is the current edition of ISO 10542‑1; it has a Corrigendum published in 2013 and an Amendment 1 published in 2021 that add/correct annex material. ISO periodically reviews standards, so users should confirm whether further amendments or a revised edition have been published at the time of use.

Q: Is it part of a series?

A: Yes — ISO 10542 was originally published in multiple parts addressing specific tiedown types and system classes; the 2012 Part 1 consolidates and replaces earlier parts (ISO 10542‑2, ‑3, ‑4, ‑5). It is also used together with related wheelchair and vehicle restraint standards such as ISO 7176‑19 and ISO 10865.

Q: What are the key keywords?

A: Wheelchair tiedown, occupant restraint, WTORS, crashworthiness, frontal impact test, surrogate wheelchair, pelvic belt, upper‑torso belt, securement, UDIG.
