Introduction
0.1 General
Class B devices are marketed and used for the purpose of activities in the water. In distinction to other
floating devices they are characterized by a typically partly immersed position of the user inside the
device.
In case of Class B1 products, i.e. the swim seat for children above three years of age (36 months), user’s
position might be such that in case of very young users (non swimmers four years and above) the body
is kept afloat und laterally supported by a surrounding inflatable structure which provides a relatively
tight fit between user and buoyant structure. This in turn incorporates the potential risk of body
entrapment in case of a capsizing.
Class B1-type products for children below three years of age (36 months) are dealt with in FprEN 13138-
3:2021.
The development of new products in this area is progressing. Beyond the classical swim seat rafts for
more dynamic action on and in the water different body postures and extended user groups have been
developed.
Class B2 products do not provide this kind of support to the user. Even if they have the circumferential
buoyant structure in common with the Class B1 products — and thus the entrapment risk if this fit
becomes too tight — flotation of the user depends on his ability to hold himself by hands or body inside
the very loosely surrounding buoyant structure.
Both classes of products include also adult use. Activities may range from passive floating to actions
like wave surfing, tubing, balancing, swinging, etc. The devices are linked with the identified risks
given in Table 1.
Class B products does not need requirements for re-embarkation because these products (in distinction
to part 3 devices) support the user in a position where the user's body is partly and permanently
immersed. The degree of immersion can vary. In case of a big floating ring e.g. (B1.1 and B2.2) the user
can be immersed up to the chest or only with the buttock. In case of B1-products (e.g. swim seat) the
human body is permanently immersed to a large degree.
Standardization is aiming for more safety with regard to all foreseeable uses.
Dealing with a partly intentionally immersed human body leads to the question of loads to be applied
for appropriate testing. For the purpose of this standard load resulting from the body weight is set
with 75 % of the body weight of the heaviest foreseeable or specified user even when in certain
circumstances this immersed body weight may be reduced to roughly 10 %. In cases where the devices
can be used for sitting on top (e.g. big rings) the maximum body weight out of the stipulated user group
is assessed as adequate.
It should be noted that this document is not related to the one and only technically clearly determined
product but to a whole diverse product group including two major design principles B1 and B2 as laid
down in the classification, see Clause 4, for Class B floating leisure articles.
0.2 Child testing
See Annex A and ISO 25649-1:20xx, Clause 4, as alternative. Use of Class B products includes children
from four years of age and above. Some essential requirement ensuring safety in use and in dangerous
situations which may occur — e.g. a capsize — cannot be simulated and verified via the application of
forces or other instrumental procedures but only by practical testing involving human test subjects or
test dummies which sufficiently represent the envisaged user groups. Children in testing increase the
nearness to real life situation but may lead to subjective results. An increased number of test cycles
are an appropriate means to get an average result which makes the subjective test more objective. The
application of test dummies reduces the nearness to real life situation but increases reproducibility of
testing. Costs and expenses are high in the beginning (production costs) but may pay off in long term

in comparison to the expense of repeated provision and operation of human test subjects. The worst
alternative is to eliminate certain requirements if they cannot be verified for the reason of lacking
either test dummies or human test subjects.
It goes without saying that any involvement of human test subjects and thus in particular child testing
is accompanied with all necessary precautions, surveillance and safety measures.
This document refers amongst others to children as test subjects. The anthropometric requirements
related to these test subjects are based on children five years and nine years of age with a body height
of 126 cm and 149 cm and a body weight of 25 kg/38 kg. Children of 14 years of age and above can be
represented by the smallest adult female person representing the fifth percentile of the anthropometric
range.
In order to provide in all cases an alternative to child testing the anthropometric data of relevant
manikins are specified for optional application in Annex A.

1 Scope
This document specifies safety requirements and test methods related to materials, safety, performance
and consumer information for classified floating leisure articles for use on and in the water according
to ISO 25649-1:20xx.
This document is to be applied with ISO 25649-1:20xx and ISO 25649-2:20xx.
This document is applicable for Class B floating leisure articles for use on and in the water according
to ISO 25649-1:20xx regardless whether the buoyancy is achieved by inflation or inherent buoyant
material.
Class B devices provide a buoyant structure with one or more body openings into which the user is
positioned partly immersed.
NOTE 1 Typical products forming Class B (see Annex B):
— floating rafts with interior body holding system (“swim seats”) mostly in circular or square shape, fantasy
shape for playing purposes;
— floating fantasy shaped structures with one or more openings to host a child’s body, with or without body
holding system;
— floating with slits or openings to put legs through any shape;
— floating rings with interior seat segments inside the circular body opening.
NOTE 2 Typical places for application:
— pools;
— protected areas of lakes, ponds;
— protected area sea shore (no offshore winds, no currents).

4 Safety requirements and test methods
4.1 General
Construction of Class B devices shall be such that it corresponds in terms of design, dimensions, safety,
strength and durability for its intended use.
The requirements set out in ISO 25649-1:20xx shall comply with these considerations. Where class B
devices are provided in several components, the requirements apply to all components. These
components shall be permanently attached if the contribute indispensably to safety and performance.
With regard to general material and design requirements Class B devices shall meet the requirements
set out in ISO 25649-1:20xx as far as applicable.
In individual cases, due to the unpredictability, valence and in determinability of existing and future
concrete products, a corresponding choice shall be made.
For the safety information markings, this document is to be applied with ISO 25649-2:20xx,
requirements.
4.2 Sizing
4.2.1 Sizing of B1 devices, fit to user’s body and test probes
4.2.1.1 Requirements
The child’s torso and thighs shall be represented by test probes representing the anthropometrically
th
relevant 95 percentile, male body dimensions of the labelled age/weight group. The probes shall slip
easily through the body or leg openings respectively (see Figure 1).
Sizing of class B1 devices shall be in accordance with the range of body weights and age groups as
specified in Table 2 (sizing safety information symbols see ISO 25649-2:20xx).
