Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

This second edition cancels and replaces the first edition (ISO 25649-4:2017), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— Addition in the introduction (0.1) of precision regarding absence of re-embarkation requirements
for Class B products;
— The normative references in Clause 2 and in the entire document are updated;
— Clause 4.1 addition of ISO 26549-1 clauses number regarding general requirements to apply;
— Sub-clause 4.2.3.1 - Table 3, modifications of smallest interior dimensions for xx-large devices;
— Addition of an informative Annex ZA regarding correspondence between this European standard
and Commission Decision No 2005/323/EC of 21/04/2005.

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
