1.1 本规程规定了评估穿着防护服的受试者ROM的测试设备和程序。 1.2 本实践涵盖运动范围和主观感知的人体工程学测量。 1.3 为了提高测试期间的安全性，该实践要求使用符合特定健康和身体健康要求的人类参与者。 1.4 本规程并不试图确定其他衣物特性，例如防护服整体的隔热性和耐蒸发性。 试验方法 F1291 和 F2370 可用于这些测量。 1.5 本标准中规定的数值应为国际单位制。 1.6 测试实验室有责任获得其机构要求的必要和适当的批准，以便使用人类参与者进行测试。 1.7 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。 1.8 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 本规程可用于评估在受控条件下穿戴的防护服套装的ROM，并可为PPE的运动评估提供指南。 4.1.1 这种做法利用了足够大的空间，允许用户在任务期间自由移动，并利用椅子和担架测量一定的身体关节活动度。 注1: 由于所需的运动范围值将与佩戴防护服时要完成的工作任务相关，最终用户应确定本标准提供的信息对其工作表现的意义。 4.2 本规程建立了基于运动范围和主观感知测量的一般评估程序。 4.2.1 获得的数据可用于评估测试参与者穿着防护服时的ROM。 4.2.2 这些数据还可能有助于研究和开发高级套装，这些套装旨在实现最佳移动性和舒适性，或减少佩戴者的压力，从而减少与穿戴防护服套装相关的潜在伤害。 4.2.3 这些数据还可能有助于第一反应组织在佩戴不同套装时比较ROM。 4.2.4 这一做法也可用于共识标准组织制定保护装置的人机工程学测试标准。 4.3 偏离本规程中的说明可能会导致显著不同的测试结果。需要有关身体关节活动度、主观评估和测试实践的技术知识，以评估哪些偏离本实践中给出的说明是重要的。所有出发必须报告结果。

1.1 This practice specifies the test equipment and procedures for assessing ROM on subjects wearing a protective clothing ensemble. 1.2 This practice covers the ergonomic measurements of range of motion and subjective perceptions. 1.3 To increase safety during testing, this practice requires the use of human participants who meet specific health and physical fitness requirements. 1.4 This practice does not attempt to determine other clothing characteristics, such as thermal insulation and evaporative resistance of the protective clothing ensemble. Test Methods F1291 and F2370 can be used for these measurements. 1.5 The values stated in this standard shall be SI units. 1.6 It is the responsibility of the test laboratory to obtain the necessary and appropriate approval(s) required by their institution for conducting tests using human participants. 1.7 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. 1.8 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 practice can be used for the evaluation of the ROM of protective clothing ensembles worn under controlled conditions and can provide guidelines for the motion evaluation of PPE. 4.1.1 This practice utilizes a space large enough to allow users to move freely during the tasks and a chair and a stretcher to measure certain body joint mobility. Note 1: Since required range of motion values will be related to the work task to be done while wearing the protective ensemble, the end user should decide meaningfulness of the information provided by this standard for the performance of their job. 4.2 This practice establishes general procedures for the evaluation based on the measurement of range of motion and subjective perceptions. 4.2.1 The data obtained can be used to evaluate the ROM of the test participant while wearing a protective clothing ensemble. 4.2.2 The data are also potentially useful in the research and development of advanced ensembles that are designed for optimal mobility and comfort or reduce strain on the wearer thereby reducing the potential injury associated with wearing the protective clothing ensemble. 4.2.3 The data are also potentially useful for first responder organizations to compare the ROM while wearing different ensembles. 4.2.4 This practice could also be used by consensus standards organizations in the development of ergonomic test criteria for protective ensembles. 4.3 Departures from the instructions in this practice have the potential to lead to significantly different test results. Technical knowledge concerning mobility of body joints, subjective evaluations, and testing practices is needed to evaluate which departures from the instructions given in this practice are significant. All departures must be reported with the results.
