| Significance and Use |

5.1?Hurdle designs can vary greatly in, for example: hurdle geometry, surface coatings, and coverings for a variety of industries. Fig. 1 shows examples of various hurdles. 5.2?Exoskeletons are being used in the industrial/occupational, military, response, medical, and recreational sectors to enhance safety and effectiveness of the user to perform tasks. Hurdles are used in many tasks performed and may include, for example, upper, lower, or full body movement in order to complete the task. For example, an exoskeleton may be used to help rehabilitate a patient who suffered a traumatic injury. And in manufacturing, warehousing, and other occupations, and other similar environments, workers in exoskeletons may traverse hurdles (for example, obstacles) in the walkways while carrying or not carrying loads, indoors or outdoors, as part of their daily activities. The testing results of exoskeletons shall describe, in a statistically significant way, how reliably the exoskeleton is able to support tasks within the specified types of environments, confinements, and terrains, and thus provide sufficiently high levels of confidence to determine the applicability of the exoskeleton. 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 test exoskeletons and the exoskeleton users 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 hurdles. The test apparatus described in Section 6 is intended to be a single or set of hurdles 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. 5.5?Although the test method was developed for the sectors listed in 5.2, it may be applicable to other operational domains. |

1.1?Purpose:? 1.1.1?The purpose of this test method, as a part of a suite of exoskeleton use test methods, is to quantitatively evaluate an exoskeletons (see Terminology F3323) safety (see 1.4) or performance, or both, for traversing hurdles. 1.1.2?Exoskeletons possess a certain set of allowable exoskeleton user movement capabilities, including user-motion adaptability, to suit operations such as: industrial/occupational, military, response, medical, or recreational. Environments in these typical sectors often pose constraints to exoskeleton user movement to various degrees. Being able to traverse hurdles, as intended by the user or test requestor, while using an exoskeleton is essential for exoskeleton deployment for a variety of tasks (for example, traversing logs, objects). This test method specifies test setup, procedure, and recording to standardize this hurdles task for testing exoskeleton user movement. 1.1.3?Exoskeletons need to function as intended, regardless of types of tasks and terrain complexities (for example, carpet, metal, masonry, rock, wood). Required movement capabilities may include, for example: walking, running, crawling, climbing, traversing gaps, hurdles, stairs, slopes, various types of floor surfaces or terrains, or confined spaces, or any combination thereof. Standard test methods are required to evaluate whether or not exoskeletons meet these requirements. 1.1.4?ASTM Subcommittee F48.03 develops and maintains international standards for task performance and environmental considerations that include but are not limited to, standards for safety, quality, and efficiency. This subcommittee aims to develop standards for any exoskeleton application as exemplified as in 1.1.2. The F48.03 test suite consists of a set of test methods for evaluating exoskeleton capability requirements. This hurdles test method is a part of the test suite. The setup, procedure, and apparatuses associated with the test methods challenge specific exoskeleton capabilities in repeatable ways to facilitate comparison of different exoskeleton models or exoskeleton capabilities to tasks. 1.1.5?The test methods quantify elemental exoskeleton use capabilities necessary for sector applications listed in 1.1.2 and perhaps others. As such, users of this standard should use either the entire suite or a subset based on their particular requirements. Users are also allowed to weight particular test methods or particular metrics within a test method differently based on their specific requirements. The testing results should collectively represent an exoskeletons overall safety or performance, or both, as required for the task. These performance data can be used: to guide procurement specifications, for acceptance testing, and for training to use exoskeletons intended for specified applications. Note 1:?Additional test methods within the suite are
anticipated to be developed to address additional exoskeleton
capability requirements, including newly identified requirements
and even for new application domains.
1.2?ExoskeletonThe exoskeleton shall be used as intended by the manufacturer to perform the test described in this test method. If the exoskeleton is not designed for hurdles-use and the test requestor intends to use the exoskeleton to perform a hurdles test (for example, for research, development of hurdles-capable use by a manufacturer, hurdles training as in medical rehabilitation applications), appropriate manufacturer approvals should be sought prior to performing the test method. 1.3?Performing LocationThis test method shall be performed in a testing laboratory or in the field where the specified apparatus and environmental conditions are implemented. 1.4?UnitsThe values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversions to inch-pound 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. 1.5?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. 1.6?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. |
