Wheelchair seating - Part 2 : determination of physical and mechanical characteristics of seat cushions intended to manage tissue integrity

ISO 16840-2:2018 specifies apparatus, test methods and disclosure requirements for wheelchair seat cushions intended to maintain tissue integrity and prevent tissue trauma. Test conditions simulate a symmetric anatomy and posture and do not represent cushion performance for specific individual users. Loads are intended to represent those seen under the pelvis of a 50th percentile wheelchair user and are not intended to assess the weight capacity of the cushion or to characterize the cushion under bariatric loads. It is possible that not all test methods apply to existing and future cushion technologies. It does not include test methods or requirements for determining the fire resistance of cushions.ISO 16840-2:2018 can also be applicable to tissue integrity management devices used as other support systems, as well as to cushions used in situations other than a wheelchair.
