本文件规定了确定手动和/或电动轮椅安全性和性能的试验方法和要求，该轮椅采用了改变轮椅乘员姿势的技术，在正常轮椅使用期间，由乘员或助手电动或手动操作。这可能包括倾斜、倾斜、提升和站立机制，或这些机制的组合。为了使轮椅能够斜倚、倾斜、升高和/或站立，轮椅需要额外的机构和机械结构来允许这些功能运行。 本文件规定了在可调范围的关键配置中测试这些轮椅所需的不同功能和强度测试。 本文件不包括轮椅，其中唯一的操作员可调节身体支撑系统（OABSS）是单独的可调节肢体或头部姿势支撑装置（例如提升腿部支撑）。 本文件不包括初始或后续为单个乘客设置轮椅期间的轮椅和姿势支撑装置定制。它也没有反映出可能影响轮椅稳定性的其他因素，例如乘员移动、座垫厚度和附加辅助设备（例如:。 g、 呼吸支持项目）。

This document specifies the test methods and requirements for determining the safety and performance of a manual and/or power wheelchair that incorporates technology to alter the posture of the wheelchair occupant, which are either electrically or manually operated by the occupant or assistant during normal wheelchair use. This can include recline, tilt, elevate and stand-up mechanisms or a combination of these. In order for a wheelchair to be able to recline, tilt, elevate and/or stand-up, the wheelchair requires additional mechanisms and mechanical structures to allow these features to operate. This document specifies the different functional and strength tests required to test these wheelchairs in critical configurations of their adjustable range. This document does not cover wheelchairs where the only operator adjustable body support system (OABSS) is adjustable limb or head postural support devices alone (e.g. elevating leg supports). This document does not include wheelchair and postural support device customization during initial or subsequent setup of a wheelchair for an individual occupant. It also does not reflect other factors that can influence wheelchair stability such as occupant movement, cushion thickness, and the addition of ancillary equipment (e.g. respiratory support items).
