Standard Test Method for Exoskeleton Use: Ladders

Importancia y uso:

5.1 Ladder designs can vary greatly in, for example: number and size of steps, geometry, and materials, and for a variety of industries. Fig. 2 shows examples of various ladders.

5.2.1 Example—A test requestor instructs that a lower-body exoskeleton is to be worn by five able-bodied users who are to complete 29 full tests to ascend and descend the standard ladder apparatus at their own pace where environmental variables are similar for all users. Upon testing, each user performed all 29 full tests which, from Appendix X1, Table X1.1, produces 90 % probability of success threshold and 95 % associated confidence with zero failures for all five users.

5.3 This test method addresses exoskeleton safety and performance requirements expressed by manufacturing, emergency responders, military, or other organizations requesting this test. The safety and performance data captured within this test method are indicative of the exoskeleton’s and the exoskeleton user’s capabilities. Having available direct information from tested exoskeleton(s) with associated performance data to guide procurement and deployment decisions is essential to exoskeleton purchasers and users.

5.4 The testing results of the candidate exoskeleton(s) shall describe, in a statistically significant way, how reliably the exoskeleton user is able to negotiate a ladder. The test apparatus described in Section 6 is intended to be a single, standardized ladder where repeatable results between exoskeletons, users, and organizations are comparable. The standard test setup and apparatus can also be used to support training and establish proficiency of exoskeleton users, as well as provide manufacturers with information about the usefulness of their exoskeleton(s) for tasks. For guidance on exoskeleton training, see Practice F3444/F3444M.

5.5 Although the test method was developed for the sectors listed in 5.2, it may be applicable to other operational domains.
