Compliance of a product to this standard requires that the relevant specific part and additionally the EN 15649-1 and EN 15649-2 are met. If a product includes multiple use related to several classes it should meet the requirements of all these classes. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. SIST EN 15649-4:2010

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, 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 suf-ficiently 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 be-ginning (production costs) but may pay off in long term in comparison to the expenses 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 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
