1.1 This practice describes a means to record the following environmental conditions that may affect the performance of exoskeletons or users of exoskeletons: ground surface, air quality, humidity, electrical interference, external sensor emission, lighting, and temperature. 1.2 The exoskeleton operating ranges for each of the conditions listed in 1.1 are described and parameterized in Section 4 and allow a basis for safety and performance comparison in test methods. The approach is to divide the list of environmental conditions into sub-conditions that represent the various aspects of the major category (for example, gravel within ground surface). Where necessary, this practice also provides guidelines (for example, electrical interference direction) to record environmental conditions in an existing environment. 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 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. 1.4 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health 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.

The standard is needed to ensure the environmental conditions are recorded in a replicable manner when test methods are performed using exoskeletons. The standard will provide a procedure and example recording sheet to allow the user to record the environmental conditions in the space where exoskeletons are used.
The title and scope are in draft form and are under development within this ASTM Committee.Back to Top
