轮椅座椅.第11部分:座垫显汗耗散特性的测定

[中文适用范围]： 本文件 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. 该方法旨在确定坐垫如何处理液体负载，但不用于确定其对持续释放液体或蒸汽的反应。本文件还规定了测量坐垫 dissipating 特性的装置及其测量方法。本文件适用于带有坐垫套的轮椅坐垫。 [外文原描述]： 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.
