ASTM F2376 - 08 Standard Practice for Classification, Design, Manufacture, Construction, and Operation of Water Slide SystemsCONTIENE:
1.1 This practice applies to the classification, design, manufacture, construction, and operation of water slide systems. Water slide systems shall be defined as rides intended for use by riders in bathing attire where the action of the ride involves possible and purposeful immersion of the rider's body either in whole or in part in water, and uses circulating water to mobilize or lubricate the rider’s transportation along a purpose built path. This includes slides used with or without vehicles as defined below. The terms water slides, waterslides, and slides shall be considered equivalent when used in this practice.
1.2 For the purposes of this practice, a water slide system includes:
1.2.1 The flume,
1.2.2 The water-circulation system,
1.2.3 The starting platform with associated means of access and egress,
1.2.4 The structural supports,
1.2.5 Vehicles or other aquatic accessories that are part of the water slide as defined by the manufacturer, and
1.2.6 Means of slide termination.
1.3 This practice shall not apply to:
1.3.1 Any water slides installed in private residences,
1.3.2 Water flume amusement rides where contact with water is merely incidental (for example, log flume rides, shoot-the-chutes),
1.3.3 Amusement rides and devices whose design criteria are specifically addressed in another ASTM standard,
1.3.4 Lazy river type attractions operating at constant elevation, constructed in the ground, and
1.4 Pre-existing designs manufactured after the effective date of publication of this practice if the design is service proven or previously compliant, as defined in Section 3.1.26 of Practice F 2291, and the manufacturer provides:
1.4.1 A historical summary of the water slide, or major modification as defined in Terminology F 747, and
1.4.2 A statement that the design is service proven or previously compliant. Water slides and major modifications to water slides may qualify as previously compliant for five years following the date of publication of this practice. Thereafter, water slides and major modifications to water slides must qualify as service proven or meet the requirements of this practice.
1.4.3 Service proven or previously compliant designs shall comply with Section 8.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.
Note 1—The conversion factor from inch-pound to metric units is 1 in. = 25.4 mm, and 1 lb = 4.4482 N.
1.6 This practice includes an Appendix, which provides additional information to enhance the user's understanding of and application of the criteria presented in this practice, for example, rationale, background, drawings, interpretation, or commentary. The information in the Appendix shall not be considered a mandatory part of this practice.
1.7 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 and health practices and determine the applicability of regulatory limitations prior to use.

la encuentras en:www.astm.org/Standards/F2376.htm y tiene un precio de $38 USD en pesos mexicanos a $13.80 = $510.00; el recibo es deducible de impuesto.
Dices que se hara una inversion en terreno (suponiendo que el costo de 1m = $50.00m.n.) de 5000m, esto seria $ 250,000;la "inversion" en la norma sería del 0.00204%.
Sugeriria al inversionista que utilice la normatividad disponible (en este caso la de los E.U.A.), estos documentos son elaborados por profesionales especializados alrededor del mundo; para ser utilizado por profesionales; entenderia que en este caso ayudaria a que:
- el anteproyecto permita la evaluacion de la inversion total.
- el proveedor (mexicano o extranjero) diseñará, instalará, y mantendrá el sistema bajo normas estrictas.
- el sistema cumplira los requistos MINIMOS de seguridad y evitara accidentes y demandas.
- evaluar al proveedor profesional (aquel que NO usa normas NO es CONFIABLE anuque posiblemente sea más "barato")
- se tenga una vision del COSTO TOTAL DE PERTENENCIA (TCO por sus siglas en ingles)
- realizar un contrato mercantil, donde quede establecida la responsabilidad CIVIL y PENAL en el diseño e instalación.
Una alternativa es contratar una a empresa profesional, aqui White paper (por su concepto en inglés) que podria ayudarte
How to select a water slide builder
There are several aspects to consider when selecting a water slide builder:
Your investment is very important; your business success depends a lot on your investment. We asked some of our park designers and some park consultants and they presented some advices to select a good water slide builder.
History. How long has the company been in business is important, because it tells you how serious and reliable the company is.
Clients. The type of clients in the company’s customer list tells a lot. If the clients in the list are important parks then you can presume that the company meets high quality standards for demanding customers. Ask your water slide possible supplier to give you a list of recent clients and ask about their experience with the water slide builder.
Re-Purchase Indicator. If a client is continuously purchasing with the same suppler is because the products and service offered are high-quality. Check with the company’s customers if they bought once or several times. Consider also the time that the client has been working with the water slide builder.
Verify design and engineering. Ask for an example of the drawings that you will receive with your project. Compare and demand the same quality and details in your final project drawings. Once again verify with previous clients of your possible water slide supplier, the design and engineering material received when buying aquatic attractions. Visit your water slide manufacturer facilities and verify that he has a specialized design and engineering staff.
Visit and see for yourself the slides. Before buying anything, take the time and visit any installations realized by your possible water slide builder. The same way that you would test, touch and drive a car that you are planning to buy, do the same thing with your water attractions and water slides. Talk to the users, talk to the maintenance responsible, talk to the lifeguards, ask the owner or manager, use the slides, test them, see how your slides will be running after several years installed.
Ask around, ask around, ask around ask around and if you have the time, visit and ride the slides yourself.
Una ultima palabra, SIEMPE utilizar a profesionales en e ramo te dara la ALTA POSIBILIDAD de que la inversion reditue al largo plazo, decia una abuela
