1.1 Purpose:
1.1.1 The purpose of this test method is to evaluate the extent to which an exoskeleton (see Section 3) improves, inhibits, or maintains (that is, does not affect) a user’s ability to recover from a stumble perturbation.
1.1.2 Exoskeletons are designed to assist specific tasks and initially tested in controlled lab or controlled field settings. However, in the real world exoskeletons encounter less structured environments and situations (for example, hospital rooms, factory floors, construction sites). Even without exoskeletons people will stumble (that is, trip) or scuff their foot. It would be helpful to understand how wearing an exoskeleton affects a person’s ability to recover from a stumble perturbation. Is one’s ability to recover hampered, enhanced, or unaltered when using an exoskeleton? This test method specifies test setup, procedure, and recording to standardize testing exoskeleton user stumble recovery.
1.2 Performing Location—This test method shall be performed in a testing laboratory where the specified apparatus and environmental conditions are available and implemented.
1.3 Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversions to inch-pound units. They are close approximate equivalents for the purpose of specifying material dimensions or quantities that are readily available to avoid excessive fabrication costs of test apparatuses while maintaining repeatability and reproducibility of the test method results. These values given in parentheses are provided for information only and are not considered 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.
