32、afety requirements 5.1 Moveable pool floors 5.1.1 General Moveable pool floors which fall under Directive 2006/42/EC 1 on Safety of Machinery shall also comply with EN ISO 12100, EN ISO 13850 and EN ISO 13857. NOTE It may be necessary to tighten the construction tolerances of the structure and finis
33、hes within the basin in order to meet the tolerances set out within this European Standard. The gradient of a moveable floor in water depth 1 350 mm shall be 6,6 %. The moveable pool floor design shall ensure the effectiveness of the water treatment system. In presence of a moveable pool floor, the
34、pool water treatment system should be specifically designed considering possible changes in designation (e.g. a swimmers pool used as non-swimmers pool). A dye test to check the correct water distribution of the complete installation, with the moveable floor in the lowest working position, is advisa
35、ble. As moveable floor influences the water distribution the result of the dye test has to be evaluated in a different way (see EN 15288-2:2008, Annex A). Moveable floors shall allow inspection, cleaning and maintenance of the area underneath. 5.1.2 Structural integrity The structural integrity of m
36、oveable floors shall be verified using the following independently assessed criteria: a vertical area load of 600 N/m2, evenly applied; a concentrated vertical area load of 2 000 N/m2over a square area of 1 m2at any point; BS EN 13451-11:2014EN 13451-11:2014 (E) 6 a concentrated vertical area load o
37、f 2 000 N/m2over an area of 2 m 2 m focussed in front of the means of exit or similar areas. NOTE The above values are valid only for use in swimming and associated activities. Different kind of uses (e.g. as a stage, a dancing floor, etc.) may require the use of different loads. 5.1.3 Inadvertent m
38、ovements Movements of a moveable floor different from those foreseen by design shall be prevented. The risks coming from small foreseeable movements (partial submersion or flexion caused by vertical area load, and so on) during use and maintenance in water shall be prevented. NOTE The requirement ca
39、n be complied with e.g. by design, securing systems, etc. 5.1.4 Prevention of entrapment Gaps on the surface of a moveable floor shall be 8 mm in one direction. The gap between the rigid part of a moveable floor and the pool shall be 50 mm in one direction. When the gap is greater than 8 mm a closur
40、e device shall be used. The design of a closure device shall involve that if a finger or toe can pass between the flexible closure device and the swimming pool walls, it shall also be possible to pull back the finger or toe. The movement of the rigid part of the moveable floor or moveable bulkhead i
41、s to be limited to avoid entrapment of a finger or toe. To achieve this, the design shall be as follows: The closure device shall have a shape which will not cut, entrap or injure (e.g. round shaped profiles). The horizontal movement of the moveable floor or moveable bulkhead when positioned in the
42、operating mode shall be limited to 50 % of the flexibility of the closure device. In the case of recessed ladders, the moveable floors working positions should abut against the vertical surface of the recessed ledges/steps in order to avoid entrapment. These closure devices shall pass the test defin
43、ed in 6.2. 5.1.5 Slip resistance When the water depth is 1 350 mm the slip resistance of the walkable area of a moveable floor shall comply with rating group 18 according to EN 13451-1:2011, Table 1. 5.1.6 Prevention of falling off When a moveable floor has an open end, the hazards connected with fa
44、lling off this end shall be prevented by the use of a moveable bulkhead, located at least at the water surface, to enclose the area of the moveable floor (preferred); by the use of a highly visible floating line, conforming to EN 13451-5, installed over the moveable floor surface, 1 m in front of th
45、e floor open end. Furthermore, the area 100 mm wide from the open end of the moveable floor edge shall be distinguishable by a contrasting colour. BS EN 13451-11:2014EN 13451-11:2014 (E) 7 NOTE It could be advisable to increase the antiskid characteristics of the area 1 m wide from the moveable floo
46、r edge, or to change the floor finishing in the same area (e.g. tactile warning). If a moveable bulkhead is used to separate the area of a moveable floor, a suitable interlocking system shall be installed to ensure that both components are set in their proper positions before it is open to use. 5.1.
47、7 Prevention of swimming underneath When a moveable floor has an open end, there shall be no access for the users to the area underneath, by the use of: a moveable bulkhead positioned at the open side of the moveable floor, or a self-acting tamper proof protection to physically prevent access to the
48、 area between the pool bottom and the moveable floor in all working positions of the moveable floor. When a moveable floor is equipped with a self-acting tamper proof protection and the adjacent pool wall has a recessed safety ledge: the recessed safety ledge should be closed at every position where
49、 the closing protection crosses the safety ledge to avoid entrapment risks; at the positions where the safety ledge is closed the pool edge should have a finger hold or handrail, according to EN 15288-1:2008+A1:2010, 5.6.2.1 and 5.6.2.2; at the positions where the safety ledge is closed a different coloured marking of the pool edge could be considered; in the area of movement/intersection of the tamper proof protection there shall be no safety step. 5.1.8 Prevention of hazards coming from movement The speed
