ISO 22880:2016

Overview

ISO 22880:2016 - "Castors and wheels - Requirements for castors for swivel chairs" specifies the technical requirements, appropriate dimensions and the test requirements for castors (with or without braking devices) normally used on swivel chairs. The standard re-establishes the earlier ISO 22880:2004 content and is intended for designers, manufacturers, test laboratories and procurement specialists working with office chair castors and wheels.

Key topics and technical requirements

ISO 22880:2016 covers classification, dimensions and a comprehensive set of performance tests. Key technical topics include:

• Classification and dimensions

  • Fixing systems (stem, circlip, threaded stem and others)
  • Castor types: Type H, W, C and U (single- and twin-wheel designs)
  • Dimensional requirements for compatibility with swivel chairs

• Test requirements and procedures

  • Impact performance
  • Electrical resistance (antistatic/ conductive castors)
  • Contact pressure
  • Item retention (retention of wheels and assemblies)
  • Static load performance
  • Brake performance (specifically for Type U castors with braking devices)
  • Dynamic testing, long-distance running and rolling resistance
  • Swivel resistance
  • Test environmental conditions, sequences, tolerances and acceptance criteria

• Conformity and marking

  • Rules for demonstrating conformity to the standard
  • Product marking requirements including identification of electrically conductive or antistatic castors/wheels

• Normative references

  • ISO 22878:2004 (test methods and apparatus) and terms from ISO 22877 are referenced for definitions and test apparatus.

Applications and who uses it

ISO 22880:2016 is practical for:

• Castor and wheel manufacturers - to design and certify castors for swivel chairs
• Office furniture designers and OEMs - to ensure component compatibility and safety
• Test laboratories and QA teams - to perform standardized tests (impact, dynamic, rolling resistance, electrical resistance)
• Procurement and compliance officers - to specify compliant components and verify conformity
• Standards bodies and regulators - to harmonize national rules and reduce technical barriers to trade

Typical applications include product development, quality assurance, supplier evaluation, safety compliance and product marking for office chair castors and wheels.
