[Current]Wheelchairs, Part 8: Requirements and test methods for static, impact and fatigue strengths
Adopts ISO 7176-8:2015 which specifies requirements and test methods for static, impact, and fatigue strength of wheelchairs including scooters. It also specifies requirements for disclosure of the test results. This standard applies to wheelchairs, including scooters, intended to carry one person, with a maximum speed not exceeding 15km/h.
