标准范围

本文件规定了使用装有压力传感器的压头表征轮椅座垫浸没和包覆性能的仪器、试验方法和披露要求。本文件扩展了用于管理组织完整性（ISO？16840？2）的产品特性，并为其他轮椅座椅测试提供了标准压头。它没有为特定的个人用户提供特定于座垫性能的信息，也不是为了描述更高负载条件下的包覆或浸入，也不是为了评估座垫的重量能力。本文件包括一种针对220毫米和255毫米压头的方法。提供了380毫米压头的尺寸，以便将该方法扩展到更大的患者模拟。

This document specifies apparatus, test methods, and disclosure requirements for characterization of wheelchair seat cushion immersion and envelopment properties using indenters instrumented with pressure sensors.This document expands the characterization of products intended to manage tissue integrity (ISO 16840？2) and provides a standardized indenter for other wheelchair seating tests.It does not provide information specific to cushion performance for a particular individual user, nor is it intended to characterize envelopment or immersion under higher loading conditions, nor to assess the weight capacity of a cushion.This document includes a method that is specific to 220 mm and 255 mm indenters. Dimensions are provided for a 380 mm indenter to allow for extension of the method to larger patient simulation.
