Standard Terminology Relating to Amusement Rides and Devices
SCOPE
1.1 This terminology is a repository of terms approved by Committee F24 and its subcommittees. Reproducing terms approved within all other individual F24 standards and guides, this terminology will provide a single location where terms related to amusement rides and devices are freely accessible to the public, committee members and can be maintained, updated and utilized as effective communication tools. Although published alphabetically, terms unique to a specific F24 standard or guide are indicated as such by the reference which follows the applicable term.
1.2 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
