ASTM F 3443 : 2020 : R2025

1.1This practice provides a structure for documenting test methods used to evaluate exoskeleton success criteria during a requested load handling task. The practice does not describe all loads, load types, nor load handling methods. Instead, this practice provides manufacturers and users with example load handling test procedures of common load handling tasks and a method to record load and test parameters so that load handling tasks can be replicated. The practice includes designs for defined artifact loads and the appendix provides design details, to further allow replication of load handling tests and test results, and examples of load handling tests.

1.2Evaluation and evaluation method would be included in another standard with inputs (for example, precision, statistical validity, etc.) provided by the test requestor.

1.3Output of the evaluation, that is, success criteria, are provided by the requestor.

1.4Loads encompass forces applied to physical objects, for example: lifting boxes, pushing a force plate or cart, carrying flexible firehose or luggage.

1.5If possible, tests using real or artifact loads should be replicable and performed in environments representative of a real-world load handling implementation.

1.6This standard includes only the use of inanimate objects.

1.7The 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 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.

1.8This 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.

1.9This 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.
