ISO/TR 13570-2:2014

Overview

ISO/TR 13570-2:2014 - Wheelchairs - Part 2: Typical values and recommended limits of dimensions, mass and manoeuvring space as determined in ISO 7176-5 - provides consolidated, evidence-based typical values and recommended limits for key wheelchair dimensions, masses and manoeuvring spaces. It covers both manual wheelchairs and electrically powered wheelchairs (including scooters) and reports values for wheelchairs in the occupied state and when folded or dismantled. Measurements and definitions follow the test methods in ISO 7176-5.

Key topics

This technical report organizes data into operational and technical measurements, including (but not limited to):

• Overall dimensions: full overall length, overall width, reduced/occupied lengths and heights, stowage length/width/height
• User-interface heights: handgrip height and related reach dimensions
• Mass properties: total mass and mass of the heaviest part
• Manoeuvring space: pivot width, reversing width, turning diameter, required corridor/doorway widths and angled corridor clearance
• Running and clearance: ground clearance, ramp transition angle
• Technical performance dimensions (critical to steering, tracking and stability): wheelbase, rear/front wheel track, camber, toe, skew, castor rake/cant/trail and wheel/handrim deviations
• Notes on data quality: many values are drawn from samples current to end‑2011; some table entries are marked “Insufficient Data (+)” and the report invites further contributions.

All measurements referenced in ISO/TR 13570-2:2014 are defined and obtained in accordance with ISO 7176-5 procedures.

Applications

ISO/TR 13570-2:2014 is practical for:

• Prescribers and clinicians - to assess fit, usability and safe selection of wheelchairs for individual occupants
• Manufacturers and designers - to guide dimensioning, performance targets and design validation of manual and powered wheelchairs
• Test laboratories - to compare measured outcomes against typical values and recommended limits defined via ISO 7176-5
• Architects, accessibility planners and public authorities - to define building clearance, doorway, lift and corridor requirements that accommodate typical wheelchair manoeuvring spaces
• Occupants and providers - to understand stowage, transport, and operational space needs

Practical uses include sizing for transfer and storage, specifying turning and reversing clearances, estimating transport and handling mass, and informing accessibility standards and building design.
