标准摘要
[中文适用范围]: 本文件规定了与未定义的轮椅座椅系统一起使用的姿势支撑装置 (PSD) 以及相关附件硬件的静态、冲击和重复负载强度的要求。 它规定了确定是否满足产品投入使用的最低性能要求的测试方法。 它还规定了测试结果的披露要求。 并非所有测试都适用于所有 PSD。 本文件包括表 1 中列出的针对这些特定类型 PSD 的测试集: 表 1 —PSD 测试索引 重复静态冲击 座垫支撑结构 XX 靠垫支撑结构 XXX 骨盆定位 XX 前躯干支撑 XX 侧向支撑 X 内侧膝部支撑 X 头部支撑XX 下臂定位装置 aa 脚部支撑 bb 注 1 座垫支撑结构是安装座垫的系统。 注 2:靠背垫支撑结构是安装靠背支撑的系统。 a 正在针对非集成下臂定位装置开发重复和静态测试。 ISO 7176-8 中定义了针对集成在轮椅内的支架的手臂支撑静态测试协议。 b ISO 7176-8 中针对集成在轮椅内的支撑件定义了静态和冲击足部支撑测试协议。 本文件也适用于其他座椅系统。 测试方法可用于验证制造商声称产品符合本文件的要求。 本文档不适用于设计为在某些静态、动态或重复负载下失效的 PSD。 本文件不适用于机动车辆碰撞条件下 PSD 的强度。 1 本文件不评估长期使用寿命。 注 1:ISO 16840-4 提供了轮椅座椅系统用作机动车辆轮椅座椅一部分时的碰撞测试方法和要求。 注2:对于大于或小于本文件规定的用户质量,可以对测试设备尺寸、安装点间距、力等进行适当的推断,并在测试报告中注明测试参数。 注 3:使用刚性替代测试夹具来提供标准化测试方法,因此本文件不涉及特定轮椅上的 PSD 测试。 [外文原描述]: This document specifies requirements for static, impact, and repetitive load strengths for postural support devices (PSDs) with associated attachment hardware intended for use with an undefined wheelchair seating system. It specifies the test methods for determining whether the minimum performance requirements have been met to release a product into use. It also specifies requirements for disclosure of the test results. Not all tests apply to all PSDs. This document is also applicable to other seating systems. The test methods can be used to verify the manufacturer’s claims that a product meets the requirements of this document. This document does not apply to PSDs that are designed to fail under certain static, dynamic, or repetitive loads. This document does not apply to the strength of PSDs under crash conditions in a motor vehicle. This document does not evaluate long-term useful life. NOTE 1 ISO 16840‑4 provides crash test methods and requirements for wheelchair seating systems when used as part of a wheelchair seat in a motor vehicle. NOTE 2 For user masses greater or less than those specified in this document, appropriate extrapolation of test apparatus dimensions, mounting point separation, forces, etc. can be carried out, and the test parameters noted in the test report. NOTE 3 Rigid surrogate test fixtures are utilized to provide a standardized test method, and consequently this document does not involve a test of a PSD on a particular wheelchair.
