EN 1069-1:2010 (E) 5 Introduction The market for water slides is extremely wide and specific and still developing. It is impossible to define an all-embracing safety specification, including dimensions and design requirements as required by a standard, without limiting the design possibilities and preventing innovative and new but safe products. This European Standard is intended to establish safety requirements and design guidance rules to serve anyone involved with water slides, especially designers, manufacturers, operators and users, to ensure safe and more efficient products. Its basic approach is the consciousness that the sliding action usually implies for the users a higher risk level than using a pool. For certain aspects of design, manufacturing, installation, operation and use only specific guidelines, without any technical specification, are given, which should be taken into consideration and be fulfilled in order to ensure safety for operators and users. SIST EN 1069-1:2010

This standard specifies general safety requirements for water slides in swimming pools of public use and specific requirements for defined types of water slides. These specific safety requirements are applicable also to not defined types as far as possible.

Any assembling, modification, adjustment or alteration of parts shall only be done by persons with appropriate experience and skills. 5.5 Durability The designer shall specify the method of protection or frequency of inspection. All components shall be protected to minimize degradation caused by corrosion or rot by an approved method. The quality of protection shall depend on the use of the components.

the users the slide is destined to; users with special needs. In the design documents possible/allowed user groups, their characteristics and limits shall be indicated.
NOTE Various risks can be involved in using a water slide, e.g. ejection from the slide, impacts, falls, burns, entrapment. For a guidance to a risk assessment, see EN 15288-2 and EN 1069-2. 6.2 Common requirements for design analysis and examination 6.2.1 General Water slides shall be treated as structures, water slides Type 1 and Type 2 only when applicable. Attention is drawn to the statutory requirements e.g. with regard to means of access and means of support. 6.2.2 Preliminary risk assessment A preliminary risk assessment shall be performed at the design stage for every water slide, with the purpose of identifying possible hazards and hazardous situations that could occur by its use, paying attention to the fact that the riding of water slides can be a vigorous physical activity and the risks associated are greater than those usually encountered in a swimming pool. Furthermore, water slides may not be safe to be used by people with reduced ability, be it temporary or permanent. The risk assessment shall also take into account the balance between risks and prevention costs and ensure the conformity of the design to this standard and to all valid national regulations.
SIST EN 1069-1:2010
EN 1069-1:2010 (E) 13 Some typical issues to be considered are: type of water slide; intended users; implementation of the slide into a new swimming pool complex; or integration of the slide into an existing facility; distance control (e.g. interference between users); access control (e.g. interference between users and non users); hazards related to the slide proper including those coming from possible vandalism especially parts freely accessible; hazards related to the landing; risky behaviours of the users; surroundings; traffic to and from the slide; influence of the use of the water slide on the regular operation of the whole facility. The risks shall be assessed against the safety of user groups, especially of those with special needs.
This assessment is even more important for water slides not yet classified in this standard, and shall also consider the specific safety requirements given in Clause 8, to comply with them as far as possible. The results of the preliminary risk assessment shall be made available to the slide tester who will perform the practical test, see 9.3. 6.2.3 Construction documents Construction documents shall be provided to the costumer which shall include all the documents required for the assessment of stability and operational safety of the water slide, and complying with this standard. The construction documents for Type 3 to Type 10 shall include as a minimum: type of water slide; declaration of conformity to this European Standard for the construction; full design and fabrication drawings; statement about intended use; construction method statement; comprehensive stress and stability analysis as required by the Eurocodes; description of special features of the water slide; description and dimensions of any clearance zones; SIST EN 1069-1:2010
EN 1069-1:2010 (E) 14 specification of all materials; specification of electrical installation; any restrictions related to the users. NOTE Water slides Type 1 and Type 2 can require a simplified documentation. 6.2.4 Design analysis and examinations A design analysis shall be carried out and certified by a qualified structural engineer, in accordance with this standard and other relevant standards. If a component test is necessary, the testing laboratory should define in advance the testing protocols and reports.
NOTE In some European countries, a certificate on the correct construction of the water slide by an inspection body can be required to certify that the entire construction of the water slide and the way it is erected complies with all relevant standards and laws 6.3 Static and dynamic loads 6.3.1 Dead load For every component of the slide, the dead load shall be determined by an engineering expert, by calculation and/or testing of the material/component used to construct the water slide. 6.3.2 Water load For the purpose of calculation, the water load shall be: a) where the inclination is ≤ 5 % the real load of the water contained in the slide;
b) for the classified types and where the inclination is > 5 %, the following: 1) Type 1: the water load is too small to be taken into account; 2) Type 2: 0,1 kN/m; 3) Type 3 to Type 5: 0,2 kN/m; 4) Type 6: 0,2 kN/m per track; 5) Type 7: 0,2 kN/m²; 6) Type 8: according to the manufacturer's specification, depending of the jet of water; 7) Type 9: 0,1 kN/m2; 8) Type 10: for the first part of the slide 0,2 kN/m, for the bowl 0,1 kN/m2, for the possible second part of the slide 0,2 kN/m; c) for non-classified types, and where the inclination is > 5 % a load twice the designed amount of water flowing on the slide.
