prEN 13138-3:2018 (E) 4 European foreword This document (prEN 13138-3:2018) has been prepared by Technical Committee CEN/TC 162 “Protective clothing including hand and arm protection and liefjackets”, the secretariat of which is held by DIN. This document is currently submitted to the CEN Enquiry. This document will supersede EN 13138-3:2014. Annex L provides details of significant technical changes between this European Standard and the previous edition EN 13138-3:2014. EN 13138, Buoyant aids for swimming instruction, consists of the following parts dealing with buoyant devices for swimming instructions for the various stages of the learning process: — Part 1: Safety requirements and test methods for buoyant aids to be worn — Part 2: Safety requirements and test methods for buoyant aids to be held — Part 3: Safety requirements and test methods for swim seats — Part 4: In-water performance testing of buoyant aids to be worn oSIST prEN 13138-3:2018

prEN 13138-3:2018 (E) 5 Introduction 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 particular 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 conformity 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 correctly 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 devices 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 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 potential 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 the 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 standard. 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), devices 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 strokes. This part 1 of prEN 13138 is applicable only in connection with part 4 of prEN 13138. 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 further 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 it). The child is positioned inside the buoyant structure, which provides buoyancy and lateral support to the body, thereby keeping the child's head above water level (class A devices = for a passive user). oSIST prEN 13138-3:2018

prEN 13138-3:2018 (E) 6 Swim seats allow young children to experience the water environment and being moved through it. Movements 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 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 child‘s standing depth will increase the risk of capsizing and 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. Part 4 of this European Standard deals with in-water performance testing for class B devices and provides objective methods of measuring the lifting and turning capacity of a swimming device by applying test manikins of various sizes. It is applicable only in connection with part 1. oSIST prEN 13138-3:2018

prEN 13138-3:2018 (E) 7 1 Scope This part 3 of EN 13138 specifies safety requirements for design, sizing, materials, strength and in-water 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 -2. This part 3 of EN 13138 applies only to devices into which 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 water environment. These devices are only intended for children aged up to 36 months with a body mass less than or equal to 18 kg. It does not apply to class B or class C devices, to pull buoys, 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.

The requirements set out were chosen to ensure compliance with these considerations. Where buoyant swimming devices are provided in several components, the requirements apply to each of the components as specified in the relevant paragraphs below. Buoyancy may be provided by inherent buoyancy materials, by inflatable chambers or by both. Where buoyancy is not inherent, devices shall have a minimum of two independent chambers safeguarding function and to allow the user to maintain the airway above water level at all times if one chamber fails. A device shall be only class A or class B or class C. These products shall be manufactured in bright colours that are in contrast to the water surface so as to be visible at all times and at any angle when in use. Wholly transparent or materials in any shade of undecorated blue in the visible areas when in use are not acceptable. For safety reasons and to assist in supervising children when used in the water, the visible areas of these products when being used shall be clearly visible from the water‘s edge or the poolside when the water is crowded, moving or may not be clear. Where criteria cannot be objectively assessed, they shall be subject to evaluation by the assessment panel. The assessment panel shall agree, by at least a 2:1 majority or by unanimity, that the device is visible when used in the water. oSIST prEN 13138-3:2018
