EN 15649-4:2010+A1:2012 (E) 5 Introduction Class B devices are marketed and used for the purpose of activities in the water. In distinction to other floating devices they are characterised 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 po-sition 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 capsiz-ing. 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 buoy-ant 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 sur-rounding buoyant structure.
Both classes of products include also adult use. Activities may reach from passive floating to actions like wave surfing, tubing, balancing, swinging, etc. The devices are linked with the identified risks given in Table 1.
Standardisation 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 ap-propriate testing. For the purpose of this standard load resulting from the body weight are 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 should be applied. It should be noted that this standard 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. Children testing
See Annex A and !EN 15649-1:2009+A1:2012", Clause 4, as alternative. Use of Class B products in-cludes 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 applica-tion 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 near-ness to real life situation but may lead to subjective results. An increased number of test cycles are an appro-priate 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 ex-penses are high in the beginning (production costs) but may pay off in long term in comparison to the ex-penses of repeated provision and operation of human test subjects. The worst alternative is to eliminate cer-tain requirements if they cannot be verified for the reason of lacking either test dummies or human test sub-jects. It goes without saying that any involvement of human test subjects and thus in particular child testing is ac-companied with all necessary precautions, surveillance and safety measures. This standard 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. SIST EN 15649-4:2010+A1:2012

EN 15649-4:2010+A1:2012 (E) 15 4.4.1.2 Testing by load application (B1, mechanical testing) 4.4.1.2.1 General Testing shall comprise the following test sequences: a) device fully inflated and load applied asymmetrically inside the device (tangentially) at the inner wall or in case of neighboured chambers at the inner wall of the outer buoyancy chamber at the place most likely to cause to failure (see Figures 4 and Figure 5); b) air chamber most likely to cause failure deflated (residual buoyancy), device loaded at the centre line of each body opening but at a distance d from centre point of the body opening. The load L shall represent 75 % of the body weight and the distance d = 25 % of the body width of the biggest allowable user of the stipulated age range. Body weights: see Table 3; body sizes: see symbol e in Table A.3. 4.4.1.2.2 Test board(s)
Material: Wood or similar rigid material. Dimensions: adjustable in length, fixed width of 200 mm, rounded edges. Features: adjustable straps for attachment to buoyant device (including single and multiple user devices), means to attach a load (steel) by hanging it vertically on the board at any place. 4.4.1.2.3 Load application for B1 devices EXAMPLE 1 Device for sitting posture as one possible embodiment of B1 products (mainly child use).

In cases where the load application board cannot be applied as shown in Figure 4 and Figure 5 a device and/or application ensur-ing the same effects shall be chosen. The figures show the load application for B1 single seaters. 4.4.2 In water behaviour, static floating stability of B1 devices for children of above eight years of age (test panel of human test subjects, device fully inflated) 4.4.2.1 Requirements When tested in accordance with 4.4.2.2 Class B1 devices shall keep the intended user(s) safely afloat with at least the head above water level without any needed intervention of the user (passive person). During test sequences (4.4.2.2, a), b), c)), including deliberate tilting, the device shall stay in or come back to a stable and safe floating position. NOTE The use of children as human test subjects is critical. Therefore testing of devices intended for children of four to five years and six years to eight years of age should be done by mechanical testing as specified in 4.4.1. Alternatively the manikin test sequence as specified in Annex A may be applied. For children above eight years human test subject testing is considered to be responsible. Testing should be performed by either using human test subjects in accordance with !EN 15649-1:2009+A1:2012", 5.6 and Table 2 or by applying the test manikins and test procedures as specified in Annex A. 4.4.2.2 Test method (human test subjects) Select test subjects
