Buoyant aids for swimming instruction - Part 1: Safety requirements and test methods for buoyant aids to be worn
The European Standard specifies safety requirements for construction, performance, sizing and marking for swimming aids intended to assist users with movement through the water whilst learning to swim or whilst learning part of a swimming stroke. It also gives methods of test for verification of these requirements.
This European Standard, Part 1, applies to devices that are designed to be worn or are carried on the body and which have either inherent buoyancy or can be inflated. It includes Class B devices intended to introduce the wearer to the range of swimming strokes. It does not apply to buoyancy aids, lifejackets or aquatic toys.

SIST EN 13138-1:2008
EN 13138-1:2008 4 Introduction The entire process of learning to swim is considered to include three stages: getting familiar with the water environment and movements in it; acquiring skills in standard swimming strokes; developing special swimming strokes and techniques. Buoyant devices for swimming instructions (in brief: swimming device(s)) are intended to assist persons (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 whilst 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 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 sorts 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 are not included in 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 swimming devices 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 for special training purposes. 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. Part 2 of this European Standard: is for devices that are held either in the hands, by the body or between the legs (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.
SIST EN 13138-1:2008
EN 13138-1:2008 5 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 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). 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 improve the in-water stability and minimise the entrapment risk 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. Shallow water is likely increase the risk of capsizing and to hinder or block the escape from the seat in case of emergency. SIST EN 13138-1:2008
EN 13138-1:2008 6 1 Scope This European Standard specifies safety requirements for construction, performance, sizing, marking and information supplied by the manufacturer for swimming aids intended to assist beginners with movement through the water whilst learning to swim or whilst learning part of a swimming stroke. It also gives methods of test for verification of these requirements. This Part 1 European Standard applies only to devices that are designed to be worn, to be securely attached to the body and which have either inherent buoyancy or can be inflated. It only applies to Class B devices intended to introduce the user to the range of swimming strokes. It does not apply to Class A or Class C devices, to swim rings, lifebuoys, buoyancy aids, lifejackets or aquatic toys. 2 Normative references The following referenced documents are indispensable for the application of this document.

5 Safety requirements 5.1 General Construction of a buoyant swimming device shall be such that it corresponds in terms of design, dimensions, safety, strength and durability for its intended use. 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 all components.
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 separate chambers safeguarding function and to allow the user to maintain the airway above water level at all times if one chamber fails.
A device may be only Class A or Class B or Class C. SIST EN 13138-1:2008
EN 13138-1:2008 9 For safety reasons these products shall be in high definition colours. Transparent or dull colour materials are not acceptable. It is recommended that the colour range yellow to red orange is most appropriate although two colour devices in green with white are also acceptable.
5.2 Buoyancy 5.2.1 Buoyancy characteristics of the complete device When tested in accordance with the procedures in EN ISO 12402-9, the device shall, with all of its buoyant components, have minimum buoyancy in accordance with Table 2. Where the Table shows a “dash” ( – ), this is intended to indicate that the device is not appropriate for the type of user.
