标准摘要
[中文适用范围]： 本文件规定了用于维持组织完整性和防止组织创伤的轮椅座垫的设备、测试方法和披露要求。 测试条件模拟对称的解剖结构和姿势，并不代表特定个人用户的缓冲性能。 负载旨在代表 50% 轮椅使用者骨盆下方的负载，并非用于评估坐垫的承重能力或表征肥胖负载下的坐垫。 并非所有测试方法都可能适用于现有和未来的缓冲技术。 它不包括确定垫层耐火性的测试方法或要求。 本文件还可适用于用作其他支撑系统的组织完整性管理装置，以及在轮椅以外的情况下使用的垫子。 [外文原描述]： ISO 16840-2:2018 specifies apparatus, test methods and disclosure requirements for wheelchair seat cushions intended to maintain tissue integrity and prevent tissue trauma. Test conditions simulate a symmetric anatomy and posture and do not represent cushion performance for specific individual users. Loads are intended to represent those seen under the pelvis of a 50th percentile wheelchair user and are not intended to assess the weight capacity of the cushion or to characterize the cushion under bariatric loads. It is possible that not all test methods apply to existing and future cushion technologies. It does not include test methods or requirements for determining the fire resistance of cushions. ISO 16840-2:2018 can also be applicable to tissue integrity management devices used as other support systems, as well as to cushions used in situations other than a wheelchair.
