标准范围

本文件规定了一种方法，用于在试验条件下确定轮椅座垫上模拟显感汗水暴露的耗散特性，该试验条件模拟具有平坦轮廓的支撑表面上的身体负荷。本试验方法适用于世界各地使用的各种座垫材料和结构。该试验方法旨在确定缓冲垫如何处理液体负载。其目的不是确定缓冲垫如何对液体或蒸汽的连续释放作出反应。本文件还规定了测量座垫（汗液）耗散特性的仪器以及测量这些特性时所采用的方法。本文件适用于包括座垫罩的轮椅座垫。注意:座垫耗散特性的重要性可能会受到所穿衣服的很大影响，例如，吸湿盖可能对坐在湿成人尿布中的患者的皮肤状况没有帮助。

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.
