ASTM F2137-19

Standard Practice for Measuring the Dynamic Characteristics of Amusement Rides and Devices

SIGNIFICANCE AND USE
4.1 This practice is intended for use whenever the dynamic characteristics of an amusement ride or device are to be determined. The existence of this practice is not intended to imply that there is a requirement to perform specific testing on amusement rides or devices.  
4.2 The general provisions of this practice provide instrumentation specifications, data acquisition and testing procedures, and documentation requirements that when applied will improve the repeatability, reliability, and utility of the test results.  
4.3 Based on the general provisions of this practice, the SARC Test specifications, when followed, will yield standardized test results regarding the patron-related, dynamic motion of amusement rides or devices. The SARC Test will facilitate both the meaningful comparison of the dynamic motion of different amusement rides or devices and the tracking of changes, if any, in the dynamic characteristics of a given ride or device.
SCOPE
1.1 This practice covers acquisition of data related to the dynamic characteristics of amusement rides and devices.  
1.2 This practice also defines the specific requirements of a Standardized Amusement Ride Characterization Test (SARC Test) for use in characterizing the dynamic motion of an amusement ride or device.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3.1 Exception—The values are reversed in Section 13 since EN standards primarily use SI units.  
1.4 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.

3.1 Definitions:
3.1.1 aliasing—a phenomenon associated with sampled data systems, wherein a signal containing significant energy at
frequencies greater than one half of the system sample frequency manifests itself in the sampled data as a lower frequency (aliased)
signal. Aliasing can be avoided only by limiting the frequency content of the signal prior to the sampling process. Once a signal
has been aliased, it is not possible to reconstruct the original signal from the sampled data.

on a logarithmic scale between F and F .
