EN 1069, Water slides, consists of the following parts:
— Part 1: Safety requirements and test methods
— Part 2: Instructions
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.
1 Scope
This document is applicable to all water slides for public use installed at open water areas or in swimming
pools.
This document specifies general safety requirements for water slides for public use installed at open
water areas or in swimming pools and specific requirements for defined types of water slides. These
specific safety requirements are also applicable to undefined types as far as possible.
These requirements concern safety and the technical rules for design, calculation and testing.

5 Materials and construction
5.1 General
Any material may be used for the construction of water slides, supports and ride enhancement devices,
provided that it fulfils the requirements of this standard.
5.2 Selection of materials
All materials and finishes used shall be:
a) suitable for the selected use, the respective surroundings and conditions;
b) able to withstand conditions of high humidity with occasional saturation and/or corrosiveness;
c) not encouraging the growth of bacteria.
The use of stressed stainless steel which could be subjected to stress corrosion shall be avoided, unless it
can be inspected and regularly cleaned. Where stainless steel is used, the grade used shall be in
accordance with Annex B.
The materials shall not contain substances which are assigned the following Risk-phrase at
concentrations exceeding 0,1 % (see Regulation (EU) No. 1272/2008):
— N317 can cause an allergic skin reaction.
NOTE Specific national regulations can apply.
5.3 Certificates
Certificates for safety critical building materials (e.g. load bearing materials) shall comply at least with
EN 10204:2004, test report “Type 2.2”.
NOTE Specific national regulations can apply.
5.4 Manufacturer and installer
The manufacturer and the installer shall ensure that persons engaged in the construction and the
installation of the water slide are competent to carry out the work, and that welders are suitably qualified
and accepted according to EN ISO 9606-1. 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. Where hollow section structural steel is used,
internal corrosion shall be considered.
5.6 Electrical installations
The relevant national and European regulations for electrical installations in and at buildings (e.g.
swimming pool, swimming pool surround) apply.
NOTE See HD 60364-7-702.
6 Design
6.1 Design guidelines
The design of a water slide, as a standard model or a one-off installation conforming to the client’s
specifications, shall consider:
— EN 15288-1, especially the preliminary risk assessment, and EN 15288-2;
— the intended user group, e.g. children, adults, users with special requirements;
— ambient conditions, e.g. indoor, outdoor.
In the design document’s 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, or
entrapment. For guidance to a risk assessment, see EN 15288-2 and EN 1069-2.
6.2 Design analysis
6.2.1 General
Water slides shall be treated as structures, Type 1 and Type 2 water slides 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 analysis
A preliminary risk analysis shall be performed by the designer 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. The preliminary risk analysis
shall consider different user groups (e.g. adults, children, people with reduced ability). The risk analysis
shall ensure the conformity of the design to this standard.
Some typical issues to be considered are:
— type of water slide;
— intended users;
— implementation of the slide into a new swimming pool complex;
— 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.
NOTE Specific national regulation can apply.
6.2.3 Construction documents
The construction documents shall be provided to the customer. They shall contain all documents required
for the assessment of the stability and operational safety of the water slide. The requirements for
documentation given in prEN 1069-2:2025, Clause 6 shall be observed.
The construction documents for Type 3 to Type 7 and special elements 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;
— specification of all materials;
— specification of electrical installation;
— any restrictions related to the users.
NOTE Type 1 and Type 2 water slides can require a simplified documentation.
6.3 Static calculations
6.3.1 General
The structural analysis of the complete slide including the supports shall be performed using the safety
concept according to Eurocode EN 1990 and associated parts using the partial factor method according
to Table 1, Table 2 and Table 3 and the combination factors according to Table 4.

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.
6.3.2 Actions in the slide area
6.3.2.1 Self-weight G
k
The self-weight of each part of the slide has to be determined by an expert using calculations or tests of
the material of each part.
The self-weight is a permanent action with the duration “permanent”.
6.3.2.2 Action of water Wa
k
To determine the load of the water, the real amount of water on the slide has to be calculated considering
cross-section and slope of the slide.
If the slide is combined from sections with different slopes, each section has to be calculated separately,
e.g. for sections with a slope of < 5 % and > 20 %. If users are able to dam up
