1.1 本指南提供了评估外骨骼一个或多个特定人体工程学参数的定量测量。此外，本指南应与实践结合使用 F3474 指导 F3519 和人体工程学应用标准指南，以防止外骨骼使用过程中受伤 2. . 1.2 本指南为工业、军事、医疗、急救和娱乐领域内外骨骼的设计、使用和建造提供了定量测量。 1.2.1 定量测量是一种可以输入数值的数据。这种测量允许对数据进行统计分析，以产生客观结果。 1.3 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南提供了一套推荐的定量测量方法，可用于评估外骨骼的任务或人类准备状态，或两者兼而有之。所有定量测量都用于人机工程学研究，以帮助客观总结评估指标的功效。 4.2 并非本指南的每个元素都适用于所有外骨骼组件或配置。 本文中的所有定量测量也并非详尽无遗。应根据围绕外骨骼最终用途应用的不确定性选择定量措施。制造商有责任确定本指南的哪些部分以及相应的措施适用于其外骨骼。 4.3 在使用定量测量方法时，能够再现外骨骼使用与非外骨骼使用之间的分析是关键标准。定量测量方法中再现性的控制方法是重复测量设计。重复测量设计涉及在不同条件下或两个或多个时间段对同一最终用户采取的同一变量的多个测量。重复测量设计的突出方面是使用最终用户作为控件。

1.1 This guide provides quantitative measures for assessing one or more specific ergonomic parameters with respect to exoskeletons. Furthermore, this guide should be used in conjunction with Practice F3474 , Guide F3519 , and Standard Guide for The Application of Ergonomics to Prevent Injury During Exoskeleton Use 2 . 1.2 This guide provides quantitative measures for the design, use, and construction of exoskeletons within the domains of industry, military, medical, first responders, and recreational. 1.2.1 Quantitative measures are a type of data that can be put into a numerical value. This type of measure allows statistical analysis to be performed on the data to yield an objective result. 1.3 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide provides a set of recommended quantitative measures which can be used to assess the task or human readiness, or both, of exoskeletons. All of the quantitative measures are used in ergonomic research to assist in objectively concluding the efficacy of an assessed metric. 4.2 Not every element of this guide may be applicable to all exoskeleton components or configurations. Nor are all the quantitative measures herein exhaustive. Selection of quantitative measures should be done based on the uncertainties surrounding the end use application of the exoskeleton. It is the manufacturer’s responsibility to determine which portions of this guide, and the corresponding measures, are applicable to their exoskeletons. 4.3 The ability to reproduce analysis between exoskeleton usage vs. non-exoskeleton usage is critical criteria in using a quantitative measures approach. A control method for reproducibility in a quantitative measures approach is a repeated measures design. A repeated measures design involves multiple measures of the same variable taken on the same end user, either under different conditions or over two or more time periods. The salient aspect of a repeated measures design is using the end user as the control.
