1 Scope
This document specifies a method for determining the dissipation characteristics of
simulated sensible perspiration exposure on seat cushions of a wheelchair under test conditions that simulate body
loading on support surfaces with flat and contoured profiles. The test method is applicable
to a wide variety of seat cushion materials and constructions that are used across
the world.
The test method is intended to determine how the cushion handles a liquid load. It
is not intended to determine how the cushion responds to a continuous release of liquid
or vapour.
This document also specifies apparatus to measure dissipation characteristics (of
perspiration) of seat cushions and the approach to be employed in measuring these
characteristics.
This document is applicable to seat cushions for wheelchairs that include a cushion
cover.
NOTE The significance of the dissipation characteristics of the seat cushion can be greatly
affected by the clothing worn, for example a moisture wicking cover might not help
the skin condition of the patient sitting in a wet adult diaper.
