SIST EN 13138-2:2021
EN 13138-2:2021 (E)
Introduction
The entire process of learning to swim is considered to include two stages:
— getting familiar with the water environment and movements in it, and
— acquiring skills in standard swimming strokes.
Buoyant aids for swimming instruction (in brief: swimming device(s)) are intended to assist users (in
particular children) to learn to swim. The design and purpose of the swimming 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
swimming devices will by itself eliminate the risk of drowning as this depends also on the behaviour of
the user and any supervision.
Although this document sets performance requirements to ensure that swimming devices perform
appropriately, it is essential that the swimming 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 swimming 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 rescue 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 are not included in this document.
For the above reasons and to differentiate these swimming devices from aquatic toys, advisory safety
measures, including marking, warning notices and user instructions are included in this document.
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
swimming devices that are intended to allow the user to become familiar with water (passive user),
swimming devices that are worn (active user) and those devices that are held by the user to improve
swimming strokes.
— Part 1 of this series is only for products that are securely attached to the body (Class B swimming
devices = for an active user). They are intended to introduce the user to the range of swimming
strokes.
— Part 2 of this series is for products 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 series deals only with products (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 swimming
devices = for a passive user).

---------------------- Page: 6 ----------------------
SIST EN 13138-2:2021
EN 13138-2:2021 (E)
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 document provide a stable, floating position for a child sitting in the swim
seat and avoid entrapment in case of capsizing. Children in swim seats do however require very close
parental supervision. Overload beyond specified body mass, breaking waves and violent external forces
are remaining risks that can cause capsizing. Use of these swimming 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.

5 Safety requirements concerning design and material
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 each of the components as specified in the relevant paragraphs
below.
Where buoyancy is not inherent, components shall have a minimum of two independent chambers
safeguarding function and safety if one chamber fails. A swimming device shall be only class A or class B
or class C.
Hand-held swimming devices shall be assessed by the assessment panel to determine whether they
comply with the ergonomic requirements of the intended user group.
There are no colour requirements for these swimming devices.
5.2 Buoyancy characteristics of the complete swimming device
5.2.1 General
When tested in accordance with the procedures 5.2.2, the swimming device shall, with all of its buoyant
components, have a minimum buoyancy of 15 N.
NOTE For illustration of class of swimming device, see Figure 1.
5.2.2 Measurement of buoyancy of complete swimming device
5.2.2.1 Apparatus
The standard equipment required consists of a weighted cage, whose submerged weight is greater than
1,1 times the expected buoyancy value of the swimming device, and a tank of fresh water, deep enough
to accommodate the swimming device horizontally with its upper surface at a depth of 100 mm to
150 mm below the water surface without contacting the sides of the tank or the bottom and with a
calibrated load cell of balance supporting it.

---------------------- Page: 11 ----------------------
SIST EN 13138-2:2021
EN 13138-2:2021 (E)
5.2.2.2 Procedure
The cage with the swimming device (fully inflated, if inflatable) shall be suspended in fresh water at a
temperature of (20 ± 5) °C from the load cell so that the upper surface of the horizontally positioned
sample is submerged at 100 mm to 150 mm below the surface. The immersed combined weight shall be
recorded as A.
It should be taken care that entrapped air has escaped before measuring.
The sample shall be removed from the cage. The weighted cage shall again be immersed and the result
recorded as B.
The buoyancy is obtained by deducting A from B.
5.3 Health and comfort
5.3.1 Innocuousness
Class C swimming devices shall not adversely affect the health or hygiene of the user. The materials shall
not, in the foreseeable conditions of normal use, release substances generally known to be toxic,
carcinogenic, mutagenic, allergenic, toxic to reproduction or otherwise harmful.
Testing shall be carried out verifying:
— Materials specifications,
— Safety data sheets relating to the materials,
— Information relating to the suitability of the materials for use with food, in medical devices, or other
relevant applications,
— Information relating to toxicological, allergenic, carcinogenic, toxic to reproduction or mutagenic
investigations on the materials,
— Information relating to ecotoxicological and other environmental investigations on the materials.
5.3.2 Edges, corners and points
Edges and corners of hard and rigid materials shall be chamfered or rounded. Round edges or corners
shall have a minimum radius of 1 mm and where a chamfer is part of the design, it shall be of (45 ± 5)°
and at least 1 mm in width. There shall be no barbs or other sharp points or features.
Testing shall be carried out by measurement and tactile assessment.
5.3.3 Attached small parts
Attached small parts on the swimming device shall withstand a pull of (90 ± 2) N in the direction most
likely to cause failure without becoming detached from the swimming device. Parts which are detached,
including those that may accidentally come away or be torn off the swimming device, shall not fit wholly
into the small parts cylinder, the specifications for which shall be in accordance with
EN 71-1:2014+A1:2018, 8.2.
5.4 Entire assembly and components
5.4.1 Thread
To sew load bearing components, only threads manufactured from synthetic materials whose properties
correspond to polyester or polyamide fibres shall be used.
10
---------------------- Page: 12 ----------------------
SIST EN 13138-2:2021
EN 13138-2:2021 (E)
Thread shall be tested using a simple burn test. When tested by a flame, fibres shall not leave an ash but
should melt or burn to leave a black pellet like residue.
5.4.2 Valves and stoppers
Inflatable class C swimming devices shall be fitted with valves ensuring sealing even when the stopper is
entirely removed. Stoppers shall be connected to the body of the valve. When orally inflated and when
tested in accordance with Annex A, all valves shall ensure that inflatable swimming devices, with an
opened stopper, retain at least 90 % of their original buoyancy after a period of 2 min.
5.4.3 Protruding parts
The protrusion of the valve/stopper or of any other protruding part shall not catch a test rope when
tested in accordance with Annex F.
5.5 Materials — Mechanical properties
5.5.1 Seam strength and durability of inflatable swimming devices
The swimming device shall remain airtight after being submitted to a cyclic pressure test when tested in
accordance with the procedures in Annex B.
5.5.2 Resistance to puncturing
Where swimming devices have air filled buoyancy chambers, the chambers shall remain airtight when
tested in accordance with the procedures in Annex C.
5.5.3 Resistance of foam and other inherent buoyant material to water absorption
5.5.3.1 General
After 24 h water immersion a sample of foam or other inherent buoyant material taken from the
swimming device shall lose no more than 10 % of its original buoyancy. Due to the small dimensions and
the shape of learn to swim devices the sample may consist of a complete component or shall provide
sample dimensions as near as possible to 10 cm x 10 cm.
5.5.3.2 Testing
The foam or other inherently buoyant sample shall be tested after conditioning according to 6.1.
Test procedure:
a) The sample is put into a net of appropriate size just to hold it;
b) the net with the sample inside is loaded with an amount of ballast weight so that it sinks to about
30 cm below the water surface;
c) buoyancy is measured by appropriate means;
d) afterwards the net without sample is measured.
The difference is the initial buoyancy A.
e) Immerse the sample in water for a period of 24 h;
f) repeat a) to d) determine buoyancy B of the sample.
The difference between the A and B is the loss of buoyancy due to water absorption.

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 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 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 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 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.
— 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 "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.
— 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.
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.

1 Scope
This European Standard specifies safety requirements for construction, performance, sizing and
marking for swimming devices intended to assist users with movement through the water in the early
stages of water awareness, while learning to swim or while learning part of a swimming stroke. It also
gives methods of test for verification of these requirements.
This part 2 of EN 13138 applies only to class C devices that are designed to be held in the hands or by
the body. Typical devices include kick boards and pull/kick boards. These devices are used to assist in
learning to swim or to assist with swimming strokes and improving specific elements of the stroke,
which have either inherent buoyancy or can be inflated.
It does not apply to pull buoys, swim rings, lifebuoys, buoyancy aids, lifejackets or aquatic toys.
