BS ISO 7176-8:1998

Wheelchairs. Requirements and test methods for static, impact and fatigue strengths | Status: Revised, Superseded, Withdrawn

1 Scope This part of ISO 7176 specifies requirements for static, impact and fatigue strength of wheelchairs including scooters intended for users whose mass does not exceed 100 kg. It specifies the test methods for determining whether the requirements have been met. It also specifies requirements for disclosure of the test results. The test methods may also be used to verify manufacturers' claims that a product exceeds the minimum requirements of this part of ISO 7176. A reference configuration is specified for adjustable wheelchairs and scooters to enable test results to be used for the comparison of performance. It applies to occupant- and attendant-propelled manual wheelchairs and electrically powered wheelchairs intended to provide indoor and outdoor mobility for people with disabilities. For electrically powered wheelchairs, it applies to those with a maximum speed of not more than 15 km/h where not more than two wheels are driven and which have three or more wheels located on two parallel, transverse axes.

NOTE 1 This part of ISO 7176 does not apply to wheelchairs where the wheels lie on more than two axes (e.g. in 'diamond' configuration).

NOTE 2 Clauses of this part of ISO 7176 may be used as a basis for developing requirements and test methods for wheelchairs not covered by this part of ISO 7176.

The application of this part of ISO 7176 is limited to wheelchairs with a maximum occupant mass of 100 kg because this is the maximum mass of test dummy available in ISO 7176-11. Further work is needed to investigate the effects of the lifestyle of people with larger body masses.

NOTE 3 For the purposes of this part of ISO 7176, "wheelchair(s)" is used as an abbreviation for manual wheelchair(s) or electrically powered wheelchair(s), including scooter(s), to which the requirements and test methods are applied.
