ASTM F3493-23

Standard Practice for Measuring Dynamic Characteristics of Water Slide Systems Using Instrumented Humans

SIGNIFICANCE AND USE
4.1 This standard practice is intended for use whenever the dynamic characteristics of a water slide are to be determined using instrumented humans.  
4.2 The use of this standard practice does not preclude the substitution of other published Amusement Industry accepted standard practices developed for use on water slides.  
4.3 The existence of this practice is not intended to imply that there is a requirement to perform specific accelerometer testing on water slides.
SCOPE
1.1 This practice covers the acquisition of quantitative data related to the dynamic characteristics of water slides when taken with instrumented humans.  
1.2 Prior to the use of this practice, the designer/engineer shall have completed and approved the testing of a new slide such that it is reasonably expected to meet the performance requirements, including accelerations, of Practice F2376-21 and ensure the slide is safe for human testing.  
1.3 This practice shall not apply to:  
1.3.1 Any other amusement rides or devices, other than water slides and water slide systems as classified by Practice F2376-21.  
1.3.2 Non-human accelerometer testing on water slides or water slide systems as defined by Practice F2376-21.  
1.4 Units—The values stated in SI units are to be regarded as the standard. Other units of measurement are included in this standard for information only and are not considered standard.  
1.5 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.  
1.6 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.
