ASTM F2374-24

1.1 This practice establishes criteria for the Design, Manufacture, Installation, Operation, Maintenance, Inspection, Training, Auditing and Major Modification of commercial use Inflatable Amusement Devices. These devices are made of flexible fabric, inflated by one or more blowers, and rely upon air pressure to maintain their shape. These devices are designed for patron activities that include, but are not limited to, bouncing, climbing, sliding, obstacle course running and interactive play.

1.1.1 Amusement devices covered by this standard are used primarily in amusement, entertainment or recreational applications. Such applications include, but are not limited to, amusement parks, theme parks, water parks, family entertainment centers, rental companies, fitness centers, gyms, gymnastics facilities, jump centers, sports facilities, skate parks, camps, schools, shopping centers, temporary special events, carnivals, fairs, festivals and municipal parks.

1.1.2 This practice includes land-based inflatable amusement devices that are designed for dry use, wet use, or a combination of wet/dry use.

1.1.3 Inflatable amusement devices covered by this standard have inflation systems that:

• 1.1.3.1 Require air to be constantly supplied in order to maintain structure, form, shape or integrity (continuous air inflatable amusement device); or
• 1.1.3.2 Maintain inflation without the need for constant air supply (captured air inflatable amusement device); or
• 1.1.3.3 Incorporate both methods of inflation into a single device.

1.1.4 The design and manufacturing requirements in Sections 5 and 6 of this standard shall not apply to inflatable amusement devices manufactured before the publication date of this standard practice.

1.1.5 The modification requirements in Section 5.3 of this standard shall not apply to major modifications performed before the publication date of this standard practice.

1.2 This practice specifically excludes the following types of inflatable devices:

• 1.2.1 Inflatable devices marketed directly to consumers for private home use by children. Those devices are covered under a separate standard, Consumer Safety Specification F2729-18.
• 1.2.2 Inflatable devices that are used for professional exhibition or stunt work; safety and rescue activities; aerial or aviation structures or devices; exhibit floats; or similar inflatable devices.
• 1.2.3 Inflatables that do not have a floor affixed to the inflatable structure (that is, the ground is exposed inside an inflated perimeter).
• 1.2.4 Inflatable devices that require a sudden loss of air to perform their intended function (for example, stunt bag style inflatable impact attenuation devices).
• 1.2.5 Inflatable devices that are designed primarily as floating devices to be installed in or on bodies of water.
• 1.2.6 Stand-alone captured air inflatable devices that are designed to contain the patron within the elevated pressure space; are designed to be mobile during its intended use; or contain less than 270 ft³ of air and do not include an anchoring or ballasting system. Examples include, but are not limited to: a water walking ball, a sports ball, a hamster ball, a hill-rolling ball.
• 1.2.7 Constant air membranes that incorporate a permanent sub-terrain box or pit to form the bottom and sides of the pressure vessel (for example, jumping pillow devices).
• 1.2.8 Air inflated devices designated to decompress or redistribute foam cubes contained in a trampoline court foam pit.

1.3 This practice includes an annex (mandatory), which provides additional information (for example, rationale, background, interpretations, drawings, commentary, and so forth) to improve the user’s understanding and application of the criteria presented in this practice. The annex information shall be interpreted as mandatory criteria.

1.4 This practice includes an appendix (non-mandatory), which provides additional information (for example, rationale, background, interpretations, drawings, commentary, and so forth) to improve the user’s understanding and application of the criteria presented in this practice. The appendix information shall not be interpreted as mandatory criteria.

1.5 The text of this standard references notes and footnotes which provide explanatory materials. These notes and footnotes shall not be considered requirements of the standard.

1.6 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.

1.7 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.
