Full title and description

ISO 22882:2016 — Castors and wheels — Requirements for castors for hospital beds. This international standard specifies technical requirements, principal dimensions and testing requirements for swivel castors used on hospital beds where the wheel diameter is 100 mm or greater and a central locking device is fitted.

Abstract

ISO 22882:2016 defines dimensional characteristics, load-capacity designation, required tests and acceptance criteria for swivel castors intended for hospital beds (wheel diameter ≥ 100 mm) with a central locking system. It covers test conditions (environmental and sequence), mechanical and electrical tests (including static and dynamic loading, swivel and wheel play, braking/locking fatigue and efficiency, electrical resistance for antistatic/conductive castors), marking and conformity requirements, and references related test-method standards.

Scope

Applies to swivel castors for hospital beds that have a wheel diameter of 100 mm or more and that are equipped with a central locking device. The standard establishes principal dimensions and characteristics, load-capacity information, required test methods and acceptance criteria to ensure safe, reliable and repeatable performance in medical environments. It does not cover castors outside the specified wheel-size range or non‑central locking designs except where otherwise noted by related standards.

Key topics and requirements

• Applicability: swivel castors for hospital beds, wheel diameter ≥ 100 mm, central locking device required.
• Dimensions and classification: principal dimensions (wheel diameter, overall height, offset), fixing systems (stem types, thread sizes), and classification by nominal load capacity.
• Load capacity: designation and verification of maximum load per castor under defined static and dynamic conditions.
• Test requirements and procedures: environmental preconditioning, test sequences and acceptance criteria for initial/final wheel play and swivel play, static and dynamic load tests, and fatigue testing of locking/braking devices.
• Braking/locking performance: efficiency checks and fatigue cycles for wheel and swivel braking/locking mechanisms with specified tolerances.
• Electrical properties: electrical resistance testing and marking requirements for electrically conductive or antistatic castors intended for use in sensitive medical areas.
• Conformity and marking: required product identification, load marking and specific marking for antistatic/conductive castors; procedures for demonstrating conformity to the standard.
• References to test-method standards: test apparatus and methods are referenced (for example ISO 22878 for test methods and apparatus; related ISO parts for terminology and other castor types).

Typical use and users

Manufacturers and designers of hospital beds and medical furniture; test and quality laboratories performing conformity and type testing; procurement/specification engineers and facilities managers in hospitals; regulatory/compliance personnel seeking to ensure mobility, braking, antistatic performance and patient safety for medical beds and trolleys.

Q: What does it cover?

A: It covers principal dimensions and classification, load-capacity designation, environmental and mechanical test methods (initial/final wheel and swivel play, static/dynamic loading, fatigue and efficiency tests for braking/locking), electrical resistance testing for antistatic/conductive castors, marking and conformity requirements.

Q: Who typically uses it?

A: Manufacturers and designers of hospital beds and medical furniture, independent test laboratories, hospital procurement and maintenance teams, and regulatory/compliance specialists.

Q: Is it current or superseded?

A: ISO 22882:2016 is the 2nd edition published in 2016 and is listed by ISO as published but scheduled for periodic review (ISO indicates it is "to be revised" as part of the normal review cycle). A committee draft for a subsequent revision has been prepared under ISO/TC 110 (project activity ongoing).
