This European Standard shall be given the status of a na
25、tional standard, either by publication of an identical text or by endorsement, at the latest by June 2015 and conflicting national standards shall be withdrawn at the latest by June 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent ri
26、ghts. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13138-3:2007.

BS EN 13138-3:2014EN 13138-3:2014 (E) 6 Intro
31、duction The entire process of learning to swim is considered to include two stages: getting familiar with the water environment and movements in it; acquiring skills in standard swimming strokes. Buoyant aids for swimming instructions (in brief: swimming device(s) are intended to assist users (in pa
32、rticular children) to learn to swim. The design and purpose of the devices are related to the above stages. Swimming devices are intended to give the user positive buoyancy in the water while maintaining the correct body position for swimming. However, it should not be assumed that standard conformi
33、ty of the devices will by itself eliminate the risk of drowning as this depends also on the behaviour of the user and any supervision. Although this European Standard sets performance requirements to ensure that swimming devices perform appropriately, it is essential that the devices are used correc
34、tly and under constant and close supervision. It is important to ensure that they are securely fitted to the appropriate size of user and that when correctly fitted, they cannot become displaced. Swim seats however should allow immediate escape in case of capsizing. Therefore the use of these device
35、s is recommended to be restricted to water out of standing depth of the user. The highest degree of protection against drowning can only be achieved by using lifejackets. It is essential that there is a clear distinction between devices intended to preserve life and those which are intended only to
36、assist buoyancy for the user when learning to swim. As swimming devices are not life preservers, they should only be used in swimming pools and other situations free from current, tides and waves. The bulk storage of some types of swimming devices could, under certain conditions, result in a potenti
37、al fire hazard. The perceived risk of such a hazard was evaluated against the actual risk to the user from materials treated with certain known toxic fire retardant chemicals. However, the fire hazard is less of a problem to the user than the risk associated with the swimming devices being put in th
38、e mouth, especially by children. For this reason, flammability requirements do not apply to this European Standard. For the above reasons and to differentiate these devices from aquatic toys, advisory safety measures, including marking, warning notices and user instructions are included in this stan
39、dard. The range both of the design and function of buoyant aids for swimming instruction varies considerably and for this reason, the standard for swimming devices has been prepared in three parts, namely devices that are intended to allow the user to become familiar with water (passive user), devic
40、es that are worn (active user) and those devices that are held by the user to improve swimming strokes. Part 1 of this European Standard is only for devices that are securely attached to the body (class B devices = for an active user). They are intended to introduce the user to the range of swimming
41、 strokes. Part 2 of this European Standard is for devices that are held either in the hands or by the body (class C devices = for an active user) and are intended to assist with improving specific elements of the swimming stroke. For adult beginners or more advanced users they can also be used for f
42、urther stages of the process to learn to swim. Part 3 of this European Standard deals only with swim seats to assist children up to 36 months in their first attempts to learn to swim (i.e. to get familiar with the “in water environment“ and moving through it). The child is positioned inside the buoy
43、ant structure, which provides buoyancy and lateral support to the body, thereby keeping the childs head above water level (class A devices = for a passive user). BS EN 13138-3:2014EN 13138-3:2014 (E) 7 Swim seats allow young children to experience the water environment and being moved through it. Mo
44、vements of lower limbs and arms are possible. The use of swim seats does however not replicate any form of a correct swimming stroke. Swim seats complying with this standard provide a stable, floating position for a child sitting in the swim seat and avoids entrapment in case of capsizing. Children
45、in swim seats do however require very close parental supervision. Overload beyond specified body weight, breaking waves and violent external forces are remaining risks that can cause capsizing. Use of these devices in water that is of the childs standing depth will increase the risk of capsizing and
46、 will hinder or block the escape from the seat in case of emergency. Buoyant swimming aids should be only a class A or a class B or a class C device. BS EN 13138-3:2014EN 13138-3:2014 (E) 8 1 Scope This part 3 of EN 13138 specifies safety requirements for design, sizing, materials, strength and in-w
47、ater performance as well as provisions for marking and the information supplied by the manufacturer for swim seats. It also specifies the relevant test methods. This standard is not applicable to products covered by EN 13138-1 and EN 131382. This part 3 of EN 13138 applies only to devices into which
48、 the user is placed and which have either inherent buoyancy or can be inflated or a combination of both. It only applies to Class A devices intended to introduce the user to the range to the water environment. These devices are only intended for children aged up to 36 months with a body mass less th
49、an or equal to 18 kg. It does not apply to Class B or Class C devices, to pull buoys, swim rings, lifebuoys, buoyancy aids, lifejackets or aquatic toys. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
