ASTM F3749-25

1.1 This practice covers a method for testing exoskeletons on human subjects in realistic simulated working scenarios described as a test method for logistic tasks, such as in box and bag handling.

1.2 The effectiveness of exoskeletons depends on the use cases, therefore studies should be carried out in dedicated experiments (1).2

1.3 The test method includes a specific logistic task consisting of carrying loads (for example, boxes or bags) and sorting them into grid boxes.

1.4 The test method in this practice is based on realistically simulated work processes that were performed by real, experienced users with at least two years of physical work in the respective work areas.

1.5 Exoskeleton—The exoskeleton shall be used as intended by the manufacturer to perform the task.

1.6 Performing Location—This practice combined with an appropriate test method, shall be performed in a testing laboratory or the field where the specified apparatus and environmental conditions are implemented.

1.7 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.8 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.

1.9 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.

5.1 Risk factors for work-related musculoskeletal disorders include lifting and carrying heavy loads, forced posture such as overhead work and repetitive tasks (2). The lower back, spine, and shoulder are frequently affected structures (3, 4).

5.2 This practice gives a standardized method for testing and assessing exoskeletons in realistic work scenarios with ideally professional users. This is expected to improve the validity of testing and assessing exoskeletons.

5.3 This practice enables the creation of a large amount of data for exoskeletons on test set-ups and the opportunity to compare and classify the exoskeleton on the global market when using the corresponding test method.

5.4 The results for comparison with the global market of the data collected as part of the Exoworkathlon study can be found on the website www.exoworkathlon.de.
