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 EN 13138-3.

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.
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 25649-1:2017, 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.

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 were

chosen to ensure compliance 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 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.
