BS ISO 7176-1:2014 pdf free.Wheelchairs Part 1: Determination of static stability.
This part of Iso 7176 specifies test methods for determining the static stability of wheelchairs. It is applicable to manual and electrically powered wheelchairs, including scooters, with a maximum speed not greater than 15 km/h. intended to provide indoor and/or outdoor mobility for one disabled person whose mass is within the range represented by ISO 7176-11.
For active stability-controlled wheelchairs, this part of ISO 7176 applies to the device in a stable, parked state.
This part of ISO 7176 provides a method for the measurement of the tipping angles (either wheelchair tipping angle or anti-tip device tipping angle), but this method is not applicable to wheelchairs with lateral anti-tip devices and does not consider sliding on the ground.
This part of ISO 7176 also includes requirements for test reports and information disclosure.

3 Terms and definitions
For the purposes of this document, the terms and definitions in ISO 7176-26 and the following apply.
3.1 active stability-controlled wheelchair
wheelchair that actively controls or enhances its stability (by electronic or other means) when static and/or when in motion
3.2 anti-tip device
device which limits the extent of tipping of a wheelchair
3.3 anti-tip device tipping angle
angle of the test platform from the horizontal at which the wheelchair starts to tip about the anti-tip device
3.4 contact point
midpoint of the region of contact between a wheel or other part of the wheelchair and the ground
Note Ito entry: In the test procedures specified in this part of ISO 7176. the ground can be the test platform or its covering that lies between the test platform and the wheel or the post.
3.5 force detection point
point at which the force under an uphill wheel is monitored
Note 1 to entry: This can be determined as the point at which a sheet of paper will slide between the wheel and the contact surface.
3.6 lockable wheel
wheel equipped with parking brake, or wheel whose rolling motion is prevented by the means of propulsion (e.g. by hands, levers, motors)
3.7 non-lockable wheel
wheel that is not a lockable wheel
3.8 parked state static position that will allow the occupant to transfer into or out of the seat
3.9 running wheel
wheel that normally runs on the surface while the wheelchair is travelling at a constant speed on a level surface
3.10 wheelchair tipping angle
angle of the test platform from the horizontal at which the vertical projection of the centre of mass moves outside of a polygon connecting the contact points of all the running wheels (to be assessed by empirical measure).BS ISO 7176-1 pdf download.
