This document specifies strength requirements and test methods for wheelchair castor assemblies. The test methods include corrosion, abrasion and fatigue conditions. This document also specifies requirements for disclosure of test results. It is applicable to castor assemblies of or developed for use in occupant and to assistant-propelled manual wheelchairs and electrically powered wheelchairs. The test requirements are also applicable to wheelchair castor assemblies not necessarily associated or supplied with a wheelchair. Castor assemblies including those with anti-tip castor wheels that do not touch the ground during wheelchair travel are outside the scope of this document.
Abstract
Overview
ISO 7176-32:2022 - "Wheelchairs - Part 32: Test method for wheelchair castor assembly durability" specifies standardized test methods and strength requirements for wheelchair castor assemblies. The standard addresses durability under corrosion, abrasion and fatigue conditions, defines test apparatus and procedures (including a fatigue testing machine with a rotating turntable), and requires disclosure of test results. It applies to castor assemblies for occupant- and assistant‑propelled manual wheelchairs and electrically powered wheelchairs, as well as stand‑alone castor assemblies. Anti‑tip castors that do not contact the ground during travel are excluded.
Key topics and technical requirements
- Test scope: Corrosion (neutral salt spray per ISO 9227), abrasion and fatigue simulation to reproduce field failures caused by outdoor environments (dust, dirt, impacts).
- Strength requirements: After testing, no visible cracks, fractures or detachments; no permanent deformation, free play or loss of adjustment that could cause loss of function; and no tyre failure.
- Castor classification: Three types by wheel diameter - Type 1 (
