oSIST prEN ISO 22882:2026 is the SIST publication aligned with the draft International Standard ISO/DIS 22882:2026 for castors and wheels used on hospital beds. It specifies technical requirements, dimensions and test requirements for swivel castors with a wheel diameter of 100 mm or more and a central locking device, so manufacturers, test laboratories and buyers can check suitability for hospital-bed use.

What does oSIST prEN ISO 22882:2026 specify?

oSIST prEN ISO 22882:2026 specifies the requirements for swivel castors for hospital beds and organizes them into six clauses plus a bibliography. The document covers scope, referenced standards, terms and definitions, dimensions and classification, testing requirements, and marking.

The main structure is:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Terms and definitions
• Clause 4 - Dimensions and classification
• Clause 5 - Requirements for testing
• Clause 6 - Marking

What are the key requirements of oSIST prEN ISO 22882:2026?

oSIST prEN ISO 22882:2026 ties the castor requirements to a defined set of dimensions, test methods and acceptance criteria. In practice, that means a manufacturer has to design the castor to the stated geometry, then verify its play, braking, load resistance and marking before claiming conformity.

Dimensions and classification

Clause 4 identifies the key characteristics of a swivel castor as wheel diameter, overall height, offset, fixing system and load capacity. Table 1 gives the principal dimensions for the listed wheel sizes, and Figures 1 to 3 show the fixing system and the operating control for central locking.

For users, this section matters because it links the product design to measurable geometry. A buyer or engineer can compare the castor design against the standard dimensions before testing begins.

Testing conditions and sequence

Clause 5 requires the test methods and apparatus from ISO 22878:2004 and specifies controlled room conditions before testing. The tests are run in a defined sequence, and the sequence depends on the castor type.

This matters because the same castor is not tested in isolation for one property only. The document makes sure the sample is conditioned and then checked in a repeatable order, so results from different laboratories are comparable.

Play, resistance and device performance

Clause 5 includes tests for initial wheel play, initial swivel play and electrical resistance. It also includes fatigue testing of the locking or braking device, plus efficiency checks for wheel braking, swivel braking and directional locking.

For practice, this means:

• wheel and swivel play must stay within the stated limits
• electrically conductive or antistatic castors must meet the resistance requirement
• locking and braking devices must keep working after repeated actions
• conductive or antistatic marking is linked to the product type

Load, running and wear checks

Clause 5 also requires static and dynamic tests on all applicable castors. After the dynamic test, the document checks the remaining wheel wear play and swivel wear play.

This is the part that shows whether the castor survives real use. A supplier needs to prove not only that the castor holds load, but also that it still performs after running over obstacles and repeated loading.

Marking

Clause 6 requires permanent product marking with the manufacturer name and/or trademark. It also requires visible marking for electrically conductive or antistatic castors or wheels.

In practice, this supports traceability and correct installation. Hospital-equipment users can identify the product and distinguish castors with different electrical properties.

What terms does oSIST prEN ISO 22882:2026 define?

oSIST prEN ISO 22882:2026 uses the terms and definitions from ISO 22877 and ISO 22878.

• Swivel castor - a castor designed to swivel so the wheel can change direction during movement.
• Central locking device - a locking arrangement that acts on the castor as part of the hospital-bed fixing system.
• Load capacity - the maximum load a wheel or swivel castor can carry while still meeting the acceptance criteria.
• Wheel play - the movement in the wheel that is measured before and after testing.
• Swivel play - the movement in the swivel function that is measured before and after testing.
• Conductive castors/wheels - castors or wheels marked for electrical conductivity.
• Antistatic castors/wheels - castors or wheels marked for antistatic use.

Who uses oSIST prEN ISO 22882:2026?

oSIST prEN ISO 22882:2026 is used by castor manufacturers, hospital-bed manufacturers, test laboratories, and quality or purchasing teams that specify medical equipment. It helps them design, test, accept and identify swivel castors intended for hospital beds.

What changed in oSIST prEN ISO 22882:2026 from the previous edition?

oSIST prEN ISO 22882:2026 cancels and replaces ISO 22882:2016 and is technically revised. The foreword states these main changes:

• fixing systems with an option for central locking are included
• a new figure shows a stem with operating control for central locking
• a figure was added to illustrate different locking device systems
• subclauses on values and tolerances were merged
• the wheel diameter table was revised, and the related final wheel wear-play table was revised
• the acceptance criteria for electrical resistance were completely revised
• the locking-action frequency and count were revised for the fatigue test
• exposure time was added to the braking and locking efficiency checks
• the directional locking device gained a horizontal tractive-force value
• the static-test tolerance was reduced
• the dynamic-test pause was aligned with the running period and given a tolerance
• Clause 6 on conformity was deleted

What does the oSIST prEN ISO 22882:2026 document contain?

oSIST prEN ISO 22882:2026 contains Figures 1 to 3 for the fixing system and central-locking arrangements, Table 1 for dimensions, Table 2 for the test sequence, and Tables 3 to 13 for test values and acceptance criteria. It also contains test procedures for wheel play, swivel play, electrical resistance, fatigue, braking and locking performance, static loading and dynamic running.

The document is set up for design verification, type testing and quality control. It gives the structure needed to measure the castor, run the required tests, and check whether the product stays within the stated performance limits after use.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
