ASTM F3493-23 PDF

Overview

ASTM F3493-23, titled Standard Practice for Measuring Dynamic Characteristics of Water Slide Systems Using Instrumented Humans, provides industry guidelines for the collection and documentation of quantitative data related to the dynamic characteristics of water slides. This standard establishes practices for measuring the accelerations and forces experienced by humans on water slides using instrumented riders. The procedure supports designers, engineers, and operators in evaluating ride performance and user experience, assisting with compliance, quality assurance, and safety analysis for water slide systems.

Key Topics

• Use of Instrumented Humans: ASTM F3493-23 focuses exclusively on water slides and water slide systems, specifying the use of humans equipped with accelerometers and related transducers to capture dynamic ride data.
• Test Preparation and Safety: Before using this standard, slides must be pretested to confirm expected performance and compliance with relevant requirements, especially those referenced in ASTM F2376.
• Test Procedure: The standard outlines detailed steps for mounting and calibrating transducers, recording acceleration measurements, and operating the water slide through multiple test cycles for reliable data acquisition.
• Data Documentation: It mandates comprehensive documentation of test parameters, including test subject identification, anthropometric data, transducer specifications, environmental conditions, and detailed records of data capture.
• Transducer Placement: Specific guidance is provided for placement and orientation of acceleration sensors on the human subject, with consideration given to various slide types and configurations.
• Calibration and Validation: The document emphasizes the importance of calibration procedures and compliance with referenced standards (ASTM F2137) for data channel, transducer, and recorder performance.

Applications

ASTM F3493-23 is a practical resource for the amusement ride industry, particularly water park operators, ride manufacturers, and safety engineers responsible for water slide systems. Key applications include:

• Safety Verification: Assessing ride accelerations to ensure that water slides perform within recommended safety limits and comply with industry standards.
• Performance Evaluation: Gathering dynamic ride data to optimize design or monitor the performance of new and existing water slide installations.
• Regulatory Compliance: Supporting documentation for adherence to national and international regulations regarding amusement ride safety and operation.
• Incident Analysis: Providing objective ride data to assist in root-cause analysis or review in case of accidents or rider complaints.
• Quality Assurance: Implementing standardized testing and data collection procedures as part of a comprehensive quality control process.
