Abstract
1 Scope This part of ISO 16840 specifies test methods for the determination of static, impact, and repetitive load strengths as well as disclosure requirements for postural support devices (PSD) with associated attachment hardware intended for use with an undefined wheelchair. This part of ISO 16840 does not apply to the strength of PSDs under crash conditions in a motor vehicle. This part of ISO 16840 does not apply to PSDs that are designed to fail under certain static, dynamic, or repetitive loads.
NOTE 1
[ISO 16840‑4](/search?q=ISO%C2%A016840%E2%80%914)
provides test methods and requirements for some PSDs when used as part of a wheelchair
seat in a motor vehicle.
NOTE 2 Performance criteria have been established in some of the defined tests. In others,
no minimum requirements are currently specified.
NOTE 3 For masses greater than 150 kg or less than 25 kg, appropriate extrapolation of test
apparatus dimensions, mounting point separation, etc. are permitted.
NOTE 4 Rigid surrogate test fixtures are utilized to provide a worst-case situation, and
consequently this part of [ISO 16840](/search?q=ISO%C2%A016840) does not test a PSD on a particular wheelchair.
NOTE 5 If one PSD achieves a higher lo...
