ASTM F3581-22

Overview

ASTM F3581-22: Standard Test Method for Exoskeleton Use: Hurdles provides a comprehensive, quantitative testing procedure to evaluate exoskeleton safety and performance during hurdle traversal. Developed by ASTM Subcommittee F48.03, this standard aims to establish consistent criteria for assessing exoskeleton usability across various sectors, including industrial, military, medical, emergency response, and recreational environments. The document outlines both the methodology for conducting hurdle tests - including test setup, apparatus, procedures, and performance metrics - and serves as an essential tool for manufacturers, end users, and procurement specialists seeking reliable exoskeleton performance data.

Key Topics

• Test Method Purpose: Quantitative evaluation of exoskeletons' ability to safely and effectively traverse hurdles, which simulates real-world obstacles and tasks.
• Applicability: Addresses full-body, upper, or lower-body exoskeletons used in varied sectors and environment types (industrial sites, rehabilitation centers, outdoor terrains, etc.).
• Hurdle Variations: Includes both barrier (stepping over) and platform (stepping onto/off) hurdles, supporting different user movement requirements.
• Test Setup and Apparatus: Specifies apparatus construction, path marking, standardization requirements, and the need for thorough documentation to enable repeatability and comparison across test sites and exoskeleton models.
• Performance Metrics: Focuses on success/repetition rates, sustained speed during traversal, user safety, user fatigue, error events (e.g., trips, stumbles), and ability to negotiate hurdles under varying environmental and loading conditions.
• Safety Considerations: Identifies common hazards such as slips, trips, and falls, and stresses the importance of safety measures, equipment, and risk mitigation strategies.
• Data Recording: Requires detail-rich documentation of pre-test information, apparatus configuration, user demographics, exoskeleton setup, environmental conditions, and test results.

Applications

ASTM F3581-22 is widely applicable across sectors where exoskeletons are used to enhance human performance and safety. Key applications include:

• Industrial and Occupational Settings: Testing exoskeletons for workers who encounter obstacles in warehouses, manufacturing plants, and construction sites.
• Military and Emergency Response: Ensuring exoskeletons enable personnel to traverse debris, barriers, or rough terrain safely during operations.
• Medical and Rehabilitation: Assessing exoskeleton utility for patients needing to relearn obstacle navigation after injury or surgery, facilitating recovery and mobility training.
• Product Development and Procurement:
  • Assisting manufacturers in validating product capabilities.
  • Providing organizations with standardized, statistically significant performance data to inform purchasing and deployment decisions.
  • Supporting acceptance testing, user training, and proficiency establishment in real-world tasks.
