1 Scope
This European Standard specifies safety and performance requirements regarding the in-water behaviour of
Buoyant aids for swimming instruction according to EN 13138-1. It specifies in-water test methods based on
the application of test manikin as well as on human test subjects.
This European Standard covers class B devices that are designed to be securely attached to the body and
which have either inherent buoyancy or can be inflated. These devices are intended to introduce the user to
the range of swimming strokes. It does not apply to 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. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 13138-1, Buoyant aids for swimming instruction — Part 1: Safety requirements and test methods for
buoyant aids to be worn
EN 13138-3, Buoyant aids for swimming instruction — Part 3: Safety requirements and test methods for swim
seats to be worn
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
buoyancy
Resultant upthrust of a swimming device when totally submerged in fresh water with its uppermost part just
below the water surface
3.2
inherent buoyancy
Upthrust provided by material which is less dense than water or by sealed chambers filled with air or gas
3.3
buoyant swimming device
garment or device which when worn or held correctly will provide the buoyancy required to become familiar
with movement through the water, assist with learning to swim or to improve swimming strokes
3.4
class B device
Buoyant swimming device intended to be securely attached to the body and to introduce the active user to the
range of swimming strokes.
3.5
device to be worn
Device having either inherent buoyancy or may be inflated to provide buoyancy and which is securely
attached to the body in such a way that it cannot be accidentally removed and so as to provide the user with
positive buoyancy.
3.6
component
Sub group of the entire device which contributes to either buoyancy, function or safety

3.7
assessment panel
Group of three people from an accredited and notified test house, all of whom are experienced in assessing
buoyant swimming devices
4 Safety and performance requirements
4.1 General
Swimming devices when correctly worn shall assist the active wearer in his/her attempts to learn to swim. The
device shall support the immersed body in a way that it does not exert forces or torques which are
counterproductive to the basic swimming techniques. If the active user becomes passive the swimming device
shall prevent the user from sinking no further than just below the water surface. In order to satisfy this
requirement the provision of the minimum buoyancy as specified in EN 13138-1 requires the correct fit and
positioning to be adhered too. Safety and performance requirements as well as in-water testing as specified
below are needed.
All tests shall be performed in chest stroke position of the test manikin / human test subject and in calm fresh
water. Depending of the type of swimming aid to be tested manikins shall be fitted with the appropriate arm
stumps as shown in figure 1, key number 8.
Test manikins as specified in EN 13138-3 and EN 13138-4 already provide the adequate residual functional
lung volume and the required body posture. Their application shall be analogue to the specification above.
If swimming aids of an equal design series cover more than one mass range only the lowest and highest mass
range needs to be tested in order to meet the requirements for the entire series.
4.2 Category of users, test manikins, human test subjects
4.2.1 Allocation
Safety and performance requirements as specified in Clause 5 shall be verified according the allocation of test
manikin and human test subject to the appropriate swimming aid as specified in table 1.

2 to 3 15 to 18 Apply test manikin III* according to EN 13138-4, Annex A
3 to 6 18 to 30 Apply test manikin VII according to EN 13138-4, Annex B
6 to 12 30 to 60 Apply human test subject 1 with a body mass of 50 to 60 kg with body
mass index of 20 - 24
Over 12 Over 60 Apply human test subject 2 with a body mass of 60 to 80 kg with body
mass index of 20 - 24
NOTE The max value of the mass range shall correspond to the weight of the test manikin / human test subject
* Test manikins I to III shall be fitted with the appropriate arm stumps as required.

4.2.2 Test methods
The following methods are acceptable for measuring the angles see Clause 5 below, but are not exclusive:
Suspension Rig see Annex C;
Underwater Photography/Video.
4.2.3 Test procedure with a Human test subject
For testing purposes the human test subjects shall don the swimming aid correctly and enter the water in an
upright posture until sufficient water depth is reached to perform the test. Arms shall be held down against the
sides of the torso. Breathing shall be stopped after the last exhalation. When the passive body achieves full
buoyancy the influence of the swimming device to the human body shall be verified. This should take between
5 and 10 seconds.
4.2.4 Test procedure for Suspension Rig
After having adjusted the suspension rig to the relevant manikin the test procedure shall be as specified
below:
a) Attach swimming device to be tested to the manikin according to manufacturer’s instructions
b) Install manikin into the suspension rig and position test rig above water (test pool)
c) Lower rig slowly and gradually into the water until both suspension strings just become loose
d) Check whether:
the manikin is prevented from sinking, see 5.1
the manikin’s flotation angle in longitudinal direction is as required, see 5.2
the swimming device gets shall not be displaced when the manikin is moved, see 5.3
flotation angle after failure of the air chamber most likely to cause failure is as required, see 5.4
NOTE If suspension strings do not become loose even if the manik
