1.1 This practice applies to the classification, design, manufacture, construction, operation, maintenance, and inspection of stationary waves.

1.2 Stationary wave systems shall be defined as a system that delivers a constantly flowing sheet of water nominally up to 24 in. thick travelling over a form allowing for patron interaction with a perpetual wave.

1.3 Significance and Use: 

1.3.1 For the purposes of this practice, a wave system could include:

1.3.1.1 The ride surface,

1.3.1.2 The ride feature pump(s),

1.3.1.3 The water filtration and disinfection system,

1.3.1.4 The runout areas,

1.3.1.5 The structural supports,

1.3.1.6 Vehicles or other aquatic accessories that are part of the water ride as defined by the designer/engineer, and

1.3.1.7 Control systems.

1.3.2 This practice shall not apply to:

1.3.2.1 Amusement rides and devices whose design criterion is specifically addressed in other ASTM standards;

1.3.2.2 Preexisting designs manufactured before the effective date of publication of this practice if the design is service proven as defined in Practice F2291; and

1.3.2.3 Deep water wave pools, Action Rivers and lazy rivers that don’t create a rideable stationary wave, or waterslides.

1.3.3 The terms stationary wave systems, standing wave systems, sheet wave systems, and wave systems shall be considered equivalent when used in this practice.

1.4 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.

1.5 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.
