The ISO 22882 hospital bed castor revision 2026 is now at the draft stage, with the public comment window closing August 25, 2026. For overseas buyers sourcing hospital beds from China, this revision is not a paperwork formality — it changes the technical requirements for wheel diameter, central locking, and antistatic properties, and it merges the former EN 12531:1998 standard into a single global document. If your supplier has not verified compliance with the draft, you risk receiving beds that fail safety inspections, cause premature castor failure, or violate destination-market regulations. This article explains what the revision changes, why it matters for your procurement decision, and how to verify that your supplier is ready.
What Is Changing in the ISO 22882 Hospital Bed Castor Revision 2026?
The revision merges the previous European standard EN 12531:1998 into ISO 22882 under the Vienna Agreement, creating a single international document. This means that buyers who previously specified EN 12531 for European projects will now see the same requirements referenced as ISO 22882. The Lithuanian Standards Board confirms the draft standard’s scope includes wheel diameter of at least 100 mm, a central locking device, and antistatic properties. The German Institute for Standardization (DIN) shows the draft open for comment as of July 2026, and the DIN NA 020 Annual Report 2025 documents the decision to merge EN 12531:1998 with ISO 22882.
For buyers, the practical consequence is that castor compliance will be judged against a stricter, harmonized set of tests. Wheel diameter below 100 mm will no longer meet the standard, central locking must be verified for both engagement and release under load, and antistatic properties must be proven with specific resistance measurements. These are not cosmetic changes; they affect patient safety and bed mobility in daily hospital use.
Why the Castor Revision Matters for Your Hospital Bed Procurement
Castors are safety-critical components. A bed that fails to lock can move unexpectedly during patient transfer, causing falls or injury. An antistatic castor prevents electrostatic discharge that could interfere with medical equipment or ignite flammable gases in surgical environments. The revision aligns with the recently published IEC 80601-2-52:2026 for medical bed safety, which means hospitals and regulatory bodies will increasingly reference both standards together.
If you are sourcing beds from China, you must verify that the castors supplied meet the draft requirements. Many factories still use castors with 75 mm wheels or lack central locking. If your shipment arrives after the standard is finalized and your destination market enforces it, you face costly rework or rejection. Even if your market does not legally require ISO 22882, specifying it gives you a defensible quality benchmark and reduces liability.
Key Technical Requirements: Wheel Diameter, Locking, and Antistatic Properties
The draft specifies three core technical requirements that buyers should verify with their supplier.
Wheel Diameter ≥ 100 mm
The minimum wheel diameter is 100 mm. Smaller wheels are common on lower-cost beds, but they increase rolling resistance and make it harder to move beds over thresholds or uneven floors. For patient transport, larger wheels also reduce vibration and improve stability. Confirm the castor specification in your purchase order, not just the bed model.
Central Locking Device
The central locking device must lock both the wheel rotation and the swivel action simultaneously. In practice, this means a single pedal or lever that locks all four castors. Verify that the locking mechanism engages fully and releases without sticking. Test it under load — a bed with a patient on it — not just empty. Ask the supplier for the test method used and the results.
Antistatic Properties
Antistatic castors have a defined electrical resistance, typically between 10^4 and 10^6 ohms, to dissipate static charge. This is critical in areas with oxygen or anesthetic gases. The draft requires a specific test method. Ask your supplier for the resistance measurement and the test standard used. If they cannot provide it, consider that a red flag.
Compliance Timeline and the August 25, 2026 Comment Window
The public comment window for the draft closes on August 25, 2026. After that, the standard will be finalized and published. The Lithuanian Standards Board lists this date explicitly. As a buyer, you should use this window to submit comments if you have technical input, but more importantly, you should use it to ask your supplier for their position on the draft.
Do not wait until the standard is final. Start the conversation now. Ask your supplier if they have reviewed the draft, if their castors meet the proposed requirements, and if they have test reports. A supplier who is unaware of the revision is a risk.
How to Verify Your Supplier’s Castor Compliance
Verification is not a single document check. It is a process. Here is what we recommend:
- Request the castor data sheet — it should list wheel diameter, locking type, and antistatic resistance.
- Ask for test reports — from an accredited laboratory, not just the factory’s own claim.
- Inspect the castors during your factory audit — measure the wheel diameter with a caliper, test the locking mechanism, and check the antistatic resistance with a tester.
- Include the requirement in your purchase order — make it a contractual condition, with penalties for non-compliance.
- Arrange a third-party inspection before shipment — have the inspector verify castor compliance against the draft.
At ZHOBAI Medical Furniture, our engineering team has been tracking the ISO 22882 revision since the draft was first circulated. In our own factory, we have already updated our castor specifications to meet the proposed requirements, and we can provide the test documentation to our clients. We have seen the consequences of non-compliant castors in the field — beds that drift on inclines, locks that fail under load, and static shocks in sensitive areas. That is why we treat this as a technical requirement, not a marketing point.
Decision Framework: Comparing Castor Options for Your Project
When you evaluate castor options, use a structured comparison. The table below outlines the key criteria and what to look for.
| Criterion | Compliant (ISO 22882 draft) | Non-compliant | Why It Matters |
|---|---|---|---|
| Wheel diameter | ≥ 100 mm | < 100 mm | Affects mobility, stability, and floor protection. |
| Central locking | Locks wheel and swivel simultaneously | Locks only wheel or swivel | Prevents unintended movement during patient transfer. |
| Antistatic resistance | 10^4 – 10^6 ohms | Outside this range or not specified | Prevents electrostatic discharge in sensitive areas. |
| Test documentation | Accredited lab report | No report or in-house only | Provides verifiable proof of compliance. |
Use this table as a checklist when reviewing supplier quotations. If a supplier cannot provide the documentation, move on.
Buyer Action Items: RFQ, Audit, and Inspection Checklist
Before you place your next order for hospital beds, take these steps:
- Update your RFQ — include a clause that castors must meet ISO 22882:2026 draft requirements, with wheel diameter ≥ 100 mm, central locking, and antistatic properties.
- Ask for the castor brand and model — then verify that brand’s compliance independently.
- Schedule a factory audit — include castor inspection in the audit checklist. Measure, test, and document.
- Arrange a pre-shipment inspection — have a third-party inspector verify castor compliance on the actual units to be shipped.
- Request the test report — from an accredited lab, and keep it on file for your records.
Following this checklist will protect you from receiving non-compliant beds. It also gives you leverage in negotiations, because you are showing that you know the technical requirements.
The ISO 22882 hospital bed castor revision 2026 is a clear signal that castor quality is being taken more seriously. Buyers who act now, verify their suppliers, and specify the new requirements will avoid costly problems later.

Practical Steps for Overseas Buyers to Prepare for the ISO 22882 Castor Revision
As an overseas buyer, you need to integrate the the clinical furnishing requirement into your procurement workflow. This means updating your request for quotation (RFQ), refining your supplier audit checklist, and planning your inspection milestones. The following actions will help you avoid costly surprises and ensure your hospital beds meet the upcoming standard.
Update Your RFQ with Specific Castor Requirements
When you issue an RFQ for hospital beds, include a dedicated section on castors. Specify that the castors must comply with the draft ISO 22882:2026 requirements, including a minimum wheel diameter of 100 mm, a central locking system that engages both wheel rotation and swivel, and antistatic properties with a defined resistance range. Ask suppliers to provide detailed technical data sheets and test reports from accredited laboratories. This upfront clarity prevents misunderstandings and sets a clear benchmark for evaluation.
Ask Targeted Questions in Your RFQ
To gauge supplier readiness, include questions such as: “Are you aware of the the clinical furnishing requirement?” “Have you updated your castor specifications to meet the draft requirements?” “Can you provide test reports from an accredited lab for wheel diameter, locking, and antistatic resistance?” “What is your timeline for full compliance?” These questions will help you identify suppliers who are proactive versus those who are lagging.
Document Checks: What to Request from Your Supplier
Before placing an order, request the following documents from your supplier:
- Castor data sheet – Verify wheel diameter, locking mechanism type, and antistatic resistance values.
- Test reports – Ensure they are from an ISO/IEC 17025 accredited laboratory, not just an in-house test.
- Declaration of conformity – If available, a statement that the castors meet the draft ISO 22882 requirements.
- Material certificates – For the castor wheel and housing, to ensure quality and traceability.
Review these documents carefully and cross-check the values against the draft standard. If anything is missing or unclear, ask for clarification before committing.
Plan Your Factory Audit with Castor Inspection in Mind
During your factory audit, allocate time to inspect castors specifically. Bring a caliper to measure wheel diameter, a tool to test the locking mechanism under load, and an ohmmeter to check antistatic resistance. Observe the production process to see if castors are sourced from a reputable manufacturer and if quality control includes these parameters. Ask to see the supplier’s incoming inspection records for castors and their testing procedures.
Set Approval Milestones in Your Purchase Agreement
To ensure compliance, establish clear approval milestones in your purchase agreement. For example:
- Pre-production sample approval – The supplier must provide a sample bed with castors for your approval before mass production.
- In-process inspection – Schedule a mid-production inspection to verify that the castors being installed match the approved sample.
- Pre-shipment inspection – Conduct a final inspection on the finished beds, focusing on castor compliance, before shipment.
Make each milestone a contractual requirement, with the right to reject non-compliant goods.
Incorporate Castor Checks into Your Inspection Plan
When you hire a third-party inspection company, provide them with a specific checklist for castors. Include items such as:
- Measure wheel diameter on a sample of beds.
- Test the central locking mechanism on each bed – engage and release it under load.
- Measure antistatic resistance using a suitable tester.
- Verify that the castor brand and model match the approved sample.
- Check for any visible defects or damage.
Ensure the inspector has the necessary tools and training to perform these tests accurately.
Review Packaging and Handling to Protect Castors
Castors can be damaged during shipping if not properly protected. Discuss packaging requirements with your supplier to ensure that castors are secured and cushioned to prevent impact damage. Ask about the packaging design – are the castors protected with foam or cardboard? Are they wrapped to avoid scratches? Also, consider the handling procedures at the destination port. Plan for a receiving inspection to check for any damage that may have occurred during transit.
Clarify Handover Responsibilities
Define who is responsible for what at each stage of the handover. Typically, the supplier is responsible for ensuring the castors meet the standard at the time of shipment. However, you should also clarify who is responsible for verifying compliance upon arrival. Will you conduct your own inspection, or will you rely on the supplier’s documentation? Establish clear communication channels for any non-conformities and agree on the process for returns or replacements.
Leverage the Comment Window to Engage with the Standard
Although you may not be a technical expert, you can still participate in the public comment process. If you have concerns about the draft requirements, consider submitting comments through your national standards body. This is an opportunity to influence the final standard. Even if you don’t submit comments, use the comment window as a deadline to ensure your supplier has a plan for compliance.
Build a Relationship with a Compliant Supplier
Finding a supplier who is already aligned with the ISO 22882 revision can save you time and risk. When evaluating suppliers, ask about their experience with international standards and their willingness to adapt. A supplier who demonstrates technical knowledge and a proactive approach is more likely to deliver compliant products. Consider visiting their factory or requesting a virtual tour to see their quality control processes firsthand.
Prepare for Potential Delays in Compliance
Even with the best planning, there may be delays in the finalization of the standard or in your supplier’s ability to comply. Build buffer time into your project schedule. Communicate your requirements early and often. If your supplier is not ready, you may need to consider alternative sources or negotiate a timeline that allows for compliance.
By taking these practical steps, you can navigate the the clinical furnishing requirement with confidence. The key is to be proactive, thorough, and clear in your communications with suppliers. This will help you secure hospital beds that are safe, compliant, and ready for the global market.
