SIGNIFICANCE AND USE 5.1 The significance of the information to be recorded in a test report allows for exoskeleton safety and performance to be contextualized with the exoskeleton configuration. Exoskeleton tests can also be replicated across similar or different exoskeletons by using this practice to record the exoskeleton test configuration in a standardized way. 5.2 Limitations of the practice are that not all exoskeletons have the same capabilities or configuration parameters. For example, for capabilities, an exoskeleton that moves the legs with electromyography during rehabilitation may behave differently in repeated use over time or within different gait courses (for example, straight or curved). For configuration, an exoskeleton that moves the legs with electromyography during rehabilitation may have varying signal gain/amplification settings. SCOPE 1.1 This practice describes a means to record the exoskeleton configuration when testing. This practice provides a method for recording exoskeleton hardware and software control parameters. 1.2 This practice: contextualizes the exoskeleton configuration during a test, including the identification and adjustment of main configuration parameters and the addition of other equipment (for example, cameras, markers) used during tests; provides a basis for comparison of the test circumstances across different exoskeletons or tests, or both (for example, varying power or spring settings, prior exoskeleton use, maximum control settings); and allows a test to be recreated. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversions to imperial units. They are close approximate equivalents for the purpose of specifying exoskeleton characteristics 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.
