Wall inlets shall be tested for:  horizontal load and deformation, if applicable, according to 5.2.3;  point load according to 5.2.4;  shear load, if applicable, according to 5.2.5. 4.2.3 Floor and wall water outlets Floor and wall water outlets shall be designed to withstand the load according to EN 13451-1:2011, A.2.2. SIST EN 13451-3:2011

For water speed test see Annex B.
4.4 Hair entrapment Wall water outlets and floor water outlets shall pass the hair entrapment test in accordance with 5.3. 4.5 Slip resistance of grilles Slip resistance of any walkable grilles shall comply with the requirements in accordance with
EN 13451-1:2011, Table 1. 4.6 Risk of suction entrapment
4.6.1 General Suction devices shall be designed and installed so as to reduce the potential for entrapment of the user. Water speed at outlets shall be ≤ 0,5 m/s. Additionally at least one of the following requirements shall be met:
a) multiple suction outlet system designed in such a way that: 1) a minimum of two functioning suction outlets per pump are installed; 2) the distance between the nearest points of the perimeters of the devices is ≥ 2 m; 3) if anyone of the suction outlets becomes blocked, the flow through the remaining suction outlet/s shall accommodate 100 % of the flow rate. b) in case of suction outlet systems with only one grill, the grille should be designed in such a way that
1) one user can not cover more than 50 % of the opening; 2) raised grilles domed opposite to the flow direction, with prevalent peripheric suction. The height of the dome shall be at least 10 % of the main dimension. Obstruction test are available (for an example see Annex A);
3) single grilles with a surface of the area circumscribed to the suction openings ≥ 1 m² (see Figure 1). SIST EN 13451-3:2011

Figure 1 — Identification of the area circumscribed to the suction openings c) a gravity feed tank. NOTE 1 Frequency of testing should be determined by risk assessment.
When retrofitting existing installations that have a single suction outlet which does not comply with the requirements of this clause, then the following actions are required:  the existing suction outlet shall be retrofitted with a grille conforming to b), or;  one or more additional suction outlets shall be provided as in a) or;  a gravity flow system fitted. In addition to the requirements in a) to c), a vacuum release system may be provided. Vacuum release systems typically respond to a blockage of a single outlet by:  releasing the vacuum by turning the pump off;  drawing water out of a vent tube to allow air into the suction system;  mechanically operating valves to reverse flow through the suction outlet(s);  opening a valve to atmosphere to cause a pump to lose prime. All vacuum release systems shall be tested on outlets which meet the structural integrity and design requirements for grilles given earlier in this standard. NOTE 2 These devices/systems are not considered “fail safe” systems as there is no known suction vacuum release system that will completely protect against all outlet entrapment hazards. Presenting Vacuum Release Systems as “fail safe” systems would promote a false sense of security among the users of these devices/systems. Safety requirements a) to c) are not applicable to:
 skimmers, because they are vented (see 4.6.3) and partly above the water level;  integrated swim jet systems, because the users are pushed away from the outlet by the action of the inlet. NOTE 3 It is recommended to install at the deck an accessible general emergency switch for the pumps level.

D inside diameter of the pipe Dmin dimension ≥ D Figure 2 — Samples of sumps 4.6.3 Skimmers Skimmers shall be effectively vented to atmosphere through openings in the lid (see Figure 3), or through a separate vent pipe.
Key 1 vent trough lid Figure 3 — Skimmer, vent through lid Skimmers shall fulfil all the general entrapment requirements in accordance with EN 13451-1; otherwise they shall be subjected to a specific risk assessment.
The leisure features shall be installed in such a way that their effects cannot cause unwanted interference with the effects of other features or cause hazards to other users of the pool. Where features involving the introduction of water into the swimming pool are installed outside the pool, users shall be informed and/or warned. Where a feature incorporates a change of depth (e.g. a submerged step) it shall be marked by contrasting colour. 4.7.2 Introduction of water and/or air from the floor Features incorporating the introduction of water and/or air under pressure from the swimming pool floor shall not be installed in depths of less than 700 mm unless: a) the vertical water speed (see 3.9) is ≤ 2 m/s (see 4.3); b) the total dynamic head in the system before the outlet is ≤ 30 kPa. For water speed test see Annex B. 4.7.3 Influence of features on the users The introduction of water and/or air under pressure shall not compromise the safety of the users (e.g. by impact against obstacles or the pool wall). Features shall not operate at full pressure immediately; they shall build up to their full pressure over a period of time, sufficient for the users to become aware. 4.8 Stream channels and rivers
4.8.1 General The speed of the water and the path of stream shall not compromise the safety of a user entering or exiting the feature.
The feature shall be designed to avoid unintentional collisions, which can cause hazards for the users. NOTE The different body masses and buoyancy of users should be considered as they can affect the action of any particular feature. The average speed of the water in the cross section of the stream channel shall be ≤ 3,5 m/s. The water depth in a stream channel shall be between 600 mm and 1 350 mm. The need of supervision of a stream channel shall be considered by a risk assessment according to EN 15288-1.
