International Standard ISO 7176-13 was prepared by Technical Committee ISO/TC 173, Technical systems and aids for disabled or handicapped persons.
ISO 7176 consists of the following parts under the general title Wheelchairs:
  • — Part 1 : Determination of static stability
  • — Part 2: Determination of dynamic stability of electric wheelchairs
  • — Part 3: Determination of efficiency of brakes
  • — Part 4: Determination of energy consumption of electric wheelchairs
  • — Part 5: Determination of overall dimensions, mass and turning space
  • — Part 6: Determination of maximum speed, acceleration and retardation of electric wheelchairs
  • — Part 7: Determination of seating dimensions — Definitions and measuring methods
  • — Part 8: Static, impact and fatigue strength tests for wheelchairs
  • — Part 9: Climatic tests for electric wheelchairs
  • — Part 10: Determination of obstacle-climbing ability of electric wheelchairs
  • — Part 11: Test dummies
  • — Part 13: Determination of coefficient of friction of test surfaces
  • — Part 14: Power and controls
 
 

This part of ISO 7176 specifies a test method for determining the coefficient of friction of a  surface that has a rough texture, such as unfinished concrete. In the event that the test method is used for smooth or polished surfaces, care should be exercised that the coefficient of friction is measured as being constant over the whole area of the test surface.

Several test procedures for wheelchairs, e.g. those specified in ISO 7176-1, ISO 7176-2, ISO 7176-3, ISO 7176-6 and ISO 7176-10, require that the coefficient of
friction of the test surface be within specified limits.
روش هایی که در استانداردهای ملی 1-10044—-2-10044—-3-10044-10—100144 ملزم می کند که ضریب اصطکاک در محدوده مشخص شده باشد.
