(Practice)Standard Practice for Load Handling When Using an Exoskeleton
Standard Practice for Load Handling When Using an Exoskeleton
SIGNIFICANCE AND USE
5.1 This practice guides the user through selection of loads and example load handling tests and procedures for use in evaluating exoskeletons worn by the user. The practice is designed to allow replication of loads and tests. Fig. 1 shows a flow chart for performing load handling test methods. Initially, the load handling test is requested by a manufacturer, user/potential user, etc. as in box 1. The environment in which the test is to be performed is documented using Practice F3427 as in box 2. This practice is shown in box 3 where documentation of the load and test results occurs. Evaluation of results occurs after the test has been completed as in box 4.
FIG. 1 Flow Chart for Performing Load Handling Test Methods
This practice is shown in the bold outlined box #3.
5.2 It is expected that this practice provides test guidance for many, although not all, load handling activities using exoskeletons that may occur. However, the test method provides examples to be used directly or as guidance for developing additional load artifacts and load handling tests.
SCOPE
1.1 This practice provides a structure for documenting test methods used to evaluate exoskeleton success criteria during a requested load handling task. The practice does not describe all loads, load types, nor load handling methods. Instead, this practice provides manufacturers and users with example load handling test procedures of common load handling tasks and a method to record load and test parameters so that load handling tasks can be replicated. The practice includes designs for defined artifact loads and the appendix provides design details, to further allow replication of load handling tests and test results, and examples of load handling tests.
1.2 Evaluation and evaluation method would be included in another standard with inputs (for example, precision, statistical validity, etc.) provided by the test requestor.
1.3 Output of the evaluation, that is, success criteria, are provided by the requestor.
1.4 Loads encompass forces applied to physical objects, for example: lifting boxes, pushing a force plate or cart, carrying flexible firehose or luggage.
1.5 If possible, tests using real or artifact loads should be replicable and performed in environments representative of a real-world load handling implementation.
1.6 This standard includes only the use of inanimate objects.
1.7 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.
1.8 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.
