5 Apparatus
5.1 Rigid, flat, horizontal test plane, with coefficient of friction of greater than 0,6 measured by the
method specified in ISO 7176-13 and of sufficient size to conduct the tests. The test plane shall have
a surface that lies between two imaginary horizontal planes 20 mm apart and has no more than 0,5 0
variation in slope or cross slope throughout the test.
The test plane shall be long enough to allow the wheelchair to reach maximum speed.
NOTE An area of approximately 10 m x 3 m is normally of sufficient size but the testing of larger and/or faster wheelchairs might need a larger test plane.
5.2 Rigid, flat, inclined area, with run up and run down, shall be long enough to allow the wheelchair to reach maximum speed and come to a stop within the stated inclination.
The test area of the ramp shall be long enough to allow the wheelchair to come to a stop within the stated inclination which shall be within the tolerance of ±10.
The testing area of the ramp shall have a surface that lies between two imaginary parallel planes 50 mm apart.
The test ramp shall have a coefficient 0 friction in the test area that meets the requirements o
ISO 7 176-13.
The test area shall run immediately from the horizontal test plane via a transition with a radius of less than 25 mm.
The traversed surface shall be free of loose material and steps greater than 5 mm in height.
A ramp approximately 10 m * 3 m is normally of sufficient area, but the testing of larger and/or faster wheelchairs may need a larger ramp.
NOTE 1 The ramp can be of a variable angle type or individual ramps for each required angle.
NOTE 2 Run up and run down areas on either end of the test area need not meet the above criteria. NOTE 3 Figure 1 provides a recommended configuration for the test area and transition.
NOTE 4 A ramp of approximately 10 m x 3 m is normally of sufficient area but the testing of larger and/or faster wheelchairs might need a larger ramp.AS/NZS ISO 7176.2 pdf download.
