Significance and Use
5.1 The significance of the information to be recorded in a test report allows for exoskeleton safety and performance to be contextualized with the exoskeleton user. Exoskeleton test results can be compared across users to determine exoskeleton usefulness, exoskeleton capability for particular users or groups of users, and standardized reporting of user information allows organizations to better replicate tests.
5.2 Limitations of the practice are that not all exoskeletons can or have the same fit to all users and therefore may change the exoskeleton capabilities. For example, as users vary in size, shape, gender, etc., an exoskeleton that fits one user may allow an increase or decrease in torque applied to the arms, legs, etc. as compared to another user, especially users at the upper and lower limits of manufacturer-suggested exoskeleton sizing. Another example is that prior surgeries or pain may affect measured exoskeleton performance as the user may, for example, favor use of one limb to another or may move different when tested with the exoskeleton versus without the exoskeleton.
5.3 Additional user measurement information may be found in the following references:
Note 1: The measurements in these references may not consider measurements of the user when dressed in appropriate clothing (for example, shoes – see 6.3.12 – 6.3.14) that will be worn when using an exoskeleton.

Scope
1.1 This practice describes a means to record the exoskeleton user information when testing. The practice provides a method for recording exoskeleton user: general information, measurements, activity level, experience with exoskeletons, prior injuries, and other pertinent information that may impact exoskeleton testing.
1.2 This practice is intended to be used with other exoskeleton test methods and practices to provide a clear representation of the exoskeleton user being tested; provides a basis for comparison of the test circumstances across different exoskeletons, users, tests, or all three; and allows a test to be recreated.
1.3 The 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 exoskeleton characteristics 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.
1.4 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.
1.5 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.
