ASTM F3794 : 25 New ASTM DRM Policy

1.1 The design and engineering of an exoskeleton is expensive. Therefore, designs typically fit more than one person; think one-size-fits-most or an exoskeleton provided in multiple sizes (for example, small, medium, and large). However, to accurately fit and accommodate a specific design range of anthropometries, the exoskeleton manufacturer leverages adjustment points or sizes, or both, on the exoskeleton. This practice expands the analysis from univariate analysis (as discussed in Guide F3661 – 24) to multivariate analysis. The advantage of multivariate analysis is that manufacturers and designers can improve exoskeleton fit by comprehensively integrating multiple dimensions rather than just one dimension in isolation, to determine multiple adjustment points on the exoskeleton. Multivariate analysis allows the exoskeleton to accommodate a specific design range of anthropometries in a mixed sex population.

1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.3 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.

1.4 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.
