Designation: F2970 − 20 F2970 − 22
Standard Practice for
Design, Manufacture, Installation, Operation, Maintenance,
Inspection and Major Modification of Trampoline Courts
This standard is issued under the fixed designation F2970; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 The purpose of this practice is to delineate requirements regarding the design, manufacture, installation, operation,
maintenance, inspection and major modification of commercial or institutional trampoline courts with the primary purpose of
amusement, entertainment or recreation.
1.2 This standard applies to institutional trampoline courts that are located in and around amusement, entertainment or recreational
facilities. Such facilities include but are not limited to trampoline parks, amusement parks, theme parks, water parks, family
entertainment centers, fitness centers, gyms, gymnastics facilities, sports facilities, skate parks, camps, shopping centers, temporary
special events, carnivals and municipal parks.
1.3 This standard applies to devices manufactured on or after the date of publication of this standard practice.
1.4 This practice establishes guidelines that will provide a level of conformity for the purpose of reducing potential hazards to
patrons, court attendants, and spectators.
1.5 This standard does not purport to address all of the hazards associated with institutional trampoline courts. The standard’s
existence alone will not prevent injuries. Like other physical activities, institutional trampoline court use involves the risk of injury,
particularly if the equipment is used improperly or if users exceed their capabilities, endurance, training, or experience.
1.6 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered as requirements of the standard.
1.7 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.
1.8 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.
This practice is under the jurisdiction of ASTM Committee F24 on Amusement Rides and Devices and is the direct responsibility of Subcommittee F24.61 on Adventure
Attractions.

software that depict the trampoline court or major modification details. These drawings and calculations shall be retained for a
minimum of 20 years from the date of last manufacture. In the case of a major modification, all records must be retained for a
minimum of 20 years.
6.2.2 Documents deemed proprietary and confidential by the manufacturer shall include a statement of such on each document.
Use of the manufacturer’s documentation and records should be limited, where possible, to the installation, maintenance,
inspection, operation and design review of the trampoline court. All other dissemination should be limited.

other important information.
6.2.4.3 Detailed drawings of all components specifically manufactured for use in the trampoline court or major modification.
6.3 Regulatory Body Review:
6.3.1 When the approval of a trampoline court, or major modification design is required by a regulatory authority, the following
documents are typically made available for review:
F2970 − 22
6.3.1.1 General assembly drawings,
6.3.1.2 Facility interface drawings and related load calculations,
6.3.1.3 Operations, maintenance, and assembly instructions, and
6.3.1.4 Information otherwise called for in accordance with the guidelines in Practice F1193-06.
6.3.1.5 Use of the manufacturer’s documentation and records should be limited to the regulatory approval process and
dissemination shall be limited to minimize disclosure of proprietary and confidential documents.
6.4 Patron Containment:
6.4.1 The trampoline court shall be designed to support and contain the patron(s) during operation. This support and containment,
that is, the patron containment, shall be consistent with the intended action of the trampoline court.
6.4.2 Parts of a trampoline court that patrons may reasonably be expected to contact shall be smooth; free from unprotected
protruding studs, bolts, screws, sharp edges and corners, and rough or splintered surfaces; and considered for impact attenuation
material as appropriate.
6.5 Security of Patron Containment System:
6.5.1 Any system or systems used to support and contain the patron(s) shall be securely fixed to the structure of the trampoline
court or immediately adjacent structure and shall have adequate strength for the intended forces produced by the trampoline court
and the reasonably foreseeable actions of the patron(s).
6.5.1.1 When an immediately adjacent wall is used for patron containment, the distance between TC frame and the wall shall not
exceed 3 in. (7.62 cm).
6.6 Loads and Strengths:
6.6.1 The designer/engineer shall perform and document a risk analysis.
6.6.2 Trampoline courts shall be designed so that load conditions expected during operation shall not cause failures during the
operational hours assumed in the analysis.
6.6.2.1 An exception to 6.6.2 may be made in the case of components and portions of structures that are intended to provide
secondary load paths during a failure condition. Components such as safety cables or links and certain limited portions of the
primary structure that they are attached to, may be designed to yield (and thus absorb a significant amount of energy) when
subjected to load conditions expected to occur during a plausible, although unlikely primary structure failure scenario. In such
cases, the expected failure mode loading shall not cause rupture to occur (that is, the stresses shall not exceed the ultimate strength).
Designs that rely on such criteria shall utilize materials that possess high elongation for components where stresses may be
expected to exceed the yield strength under failure mode loading conditions.
6.7 Patron Weight:
6.7.1 The weight assigned to an adult or child patron, for design purposes, shall be 170 lb (77.11 kg).
6.7.2 The designer/engineer may assign higher weight values for design purposes in accordance with the requirements of this
standard practice.
6.7.3 As a nonfatigue, dynamic case, trampoline courts shall be designed for occasional full or partial loads of large adult
participants weighing 300 pounds (136.08 kg) per participant or an appropriate lesser amount if recommended by the trampoline
court manufacturer. This means that if an adult patron weighing 300 pounds (136.08 kg) is restricted from participation by signage
or other means recommended by the manufacturer, then the trampoline court does not have to be designed to accommodate for
F2970 − 22
occasional full or partial loads of large adult patrons weighing 300 pounds (136.08 kg). In this case, the trampoline court shall be
designed to accommodate occasional full or partial loads of the heaviest adult patrons that the trampoline court is designed to
accommodate.
6.8 Variable loads (that is, live load) for a trampoline court include all loads that fluctuate with respect to time. Variable loads are
divided into four subsets: operational loads, nonoperational loads, environmental loads, operation in wind and non-operational in
wind.
6.8.1 Operational (Dynamic) Loads:
6.8.1.1 Operational loads include varying loads normally encountered during operation of the trampoline court.
6.8.2 Nonoperational Loads:
6.8.2.1 All loads associated with transportation or handling or both (that is, setting up, tearing down) and ongoing maintenance
of portable and permanent trampoline courts shall be considered in the analysis.
6.8.3 Environmental Loads:
6.8.3.1 Portable trampoline courts shall be designed to resist all designer/engineer defined environmental loads.
6.8.3.2 Fixed or permanent trampoline courts shall be designed to resist all applicable environmental loads for the intended
location in accordance with the environmental loads in the applicable building codes for the intended location.
6.8.3.3 The designer/engineer shall clearly indicate the environmental loads the trampoline court was designed for, in the operating
and maintenance instructions. Refer to Practice F1193-06. In addition to the environmental load information, any restrictions,
limitations, or special procedures associated with trampoline courts exposed to these environmental loads shall be included.
6.8.4 Operation in Wind:
6.8.4.1 As a minimum, trampoline courts exposed to wind shall be designed to operate in winds up to 34 mph (15 m/s).
6.8.4.2 The designer/engineer or manufacturer shall include any restrictions, limitations, or special procedures for the operation
of a trampoline court exposed to wind, in the operating and maintenance instructions. See section on Manufacturer’s Responsibility
of Practice F1193-06.
6.8.5 Nonoperational in Wind:
6.8.5.1 The designer/engineer or manufacturer shall include any restrictions, limitations, or special procedures for nonoperating
or out-of-service trampoline courts, and their associated components exposed to wind, in the operating and maintenance
instructions. See section on Manufacturer’s Responsibility of Practice F1193-06.
6.9 Design:
6.9.1 A structural analysis shall be performed for each trampoline court to verify that there is adequate structural capability in the
design.
6.9.2 The type of calculation or analysis selected shall be a widely recognized and generally accepted engineering practice.
6.9.3 The structural analyses performed shall consider and incorporate all significant loads and identify all significant stresses and
strains that are anticipated to be experienced by the trampoline court.
6.9.4 The required strength of the structure and its elements shall be demonstrated both statically and dynamically using a
minimum of five times the weight of an adult patron per 6.7.1.
6.9.5 Structures shall be analyzed to verify that significant plastic deformation or collapse or both does not occur under any
F2970 − 22
anticipated loading condition, consistent with the analysis expected to occur a limited number of times throughout the operational
hours used in the design. Examples include environmental loads, patrons attempting to apply excessive (that is, abusive) loads, and
extremely heavy patron weights.
6.9.6 A deflection analysis shall be performed if deformations in structural members or structural systems due to expected loading
conditions could impair the serviceability of the structure.
6.9.7 The structural analysis for the trampoline court shall consider “strength” and “fatigue” criteria in the evaluation of stresses
resulting from the application of loads. The number of times that a specific load or combination of loads is expected to occur
throughout the designated number of operational hours for the trampoline court shall determine whether the resulting stress levels
will be compared to strength or strength and fatigue material allowables. The method of analysis and load factors applied to specific
loads shall be selected and based upon the number of times loads are expected to occur during the specified number of operational
hours (that is, strength versus fatigue evaluation).
6.9.8 The yield and ultimate strengths and fatigue properties of the materials utilized for all components that could affect safety
upon failure of the component shall be evaluated. Empirical testing, or empirical testing in combination with analysis, may be used
as a means of evaluating the strength and fatigue properties of the materials for these components. If empirical testing is used for
evaluation, the designer/engineer shall clearly specify and describe the testing procedure and refer to the section on Testing of
Practice F1193-06.
