Introduction This informative annex has been included with the purpose of providing the rationales for the inclusion of some of the requirements given in this standard Where appropriate, relevant clause numbers in the standard are given in this annex and the relevant reference for the annex is given in the normative part of the standard Chair mounted seats are products intended to be mounted on an adult’s chair Some aspects (e.g stability) depend upon the adult’s chair on which the chair mounted seat is fitted As the safety of adult’s chairs is out of the scope of this standard, only requirements for chair mounted seats are addressed (e.g chair attachment system, adult’s chair dimensions, etc.) A.2 Chemical hazards (see Clause 6) Children up to the age of 24 months spend a considerable amount of time both mouthing and chewing It is important that quantities of certain elements which may have a harmful effect if a child has access for mouthing and chewing should be limited A.3 Thermal hazards (see Clause 7) The risk that a child sitting in the chair mounted seat may come close to or be in contact with a source of ignition is low However, if the product should come close to, or be in contact with an ignition source, the carer shall be able to remove the child before injury occurs Flash effect has been addressed A.4 Mechanical hazards (see Clause 8) A.4.1 Entrapment hazards (see 8.2) A hazard is recorded, when the child traps his finger within an opening and the circulation of blood is reduced These risks rise together with higher willingness of the child to explore his environment Even when he is able to move by himself, the child may not always be able to remove his fingers from a potential hazard Reducing the dimensions as the depth of free openings and gaps may avoid any hazard The shape is also to be considered for assessment of the risk: a bounded circular shape will cause reduction of blood circulation A.4.2 Hazards due to moving parts (see 8.3) Hazards from moving parts are related to products and rigid parts of products that move in use A child’s finger may be crushed, cut or even severed if the fingers become trapped between parts of a product that move 22 BS EN 16120:2012+A1:2014 EN 16120:2012+A1:2014 (E) Compression points may exist if one component can move relative to another part reducing the separation between the components This risk is more severe if parts move under loads such as body weight, component weight or the application of powered mechanisms Compression points between the chair mounted seat and the chair are variable due to the adult chair design: therefore they cannot be assessed The design of the chair mounted seat should aim to minimise compression hazards as far as possible Shearing hazards occur when two parts move relative to each other and act like scissors This risk is more severe if parts move under loads such as body weight, component weight or the application of powered mechanisms A.4.3 Entanglement hazards (see 8.4) If cords, ribbons and narrow fabrics are sufficiently long to encircle a child’s neck there is a risk of strangulation Loops which can pass over a child’s head also present a risk of strangulation A.4.4 Choking and ingestion hazards (see 8.5) Choking is a serious hazard which occurs when a child’s internal airways are blocked and its breathing is impeded so that air cannot pass into the lungs Brain damage can occur as a result Ingestion hazards result from small components passing into the child’s digestive system, which may cause toxic contamination or an internal blockage or lacerations The requirements given limit the size of components on the chair mounted seats that are either detachable or could be pulled off by the child A.4.5 Suffocation hazards (see 8.6) If a child’s external airways, mouth and nose are blocked simultaneously, air cannot pass into the child’s lungs and brain damage can occur A.4.6 Hazardous edges, corners and protruding parts (see 8.7) Sharp edges and protrusions on the chair mounted seat could cause cuts, lacerations or abrasions to a child’s skin Sharp points could puncture a child’s skin or eye A.4.7 Hazards from inadequate structural integrity (see 8.8) Any major failure of the structure of the chair mounted seat could cause harm to the child A.4.8 Hazards due to inadequate size (see 8.11) As the adult chairs can have different sizes, the consumer has to be aware of the minimum and maximum (as applicable) dimensions of the chair where the chair mounted seat can be installed A safety margin in the determination of the minimum dimensions has been added to reduce the risk of bad installation 23 BS EN 16120:2012+A1:2014 EN 16120:2012+A1:2014 (E) Annex B !(informative) A-deviation A-deviation: National deviation due to regulations, the alteration of which is for the time being outside the competence of the CEN-CENELEC national member This European Standard does not fall under any Directive of the EU In the relevant CEN-CENELEC countries these A-deviations are valid instead of the provisions of the European Standard until they have been removed FRANCE The French decree N° 91 1292 of December 20, 1991 relating to the prevention of hazards resulting from the use of child care articles, as published in the Official Journal of the French Republic of December 24, 1991, provides under article of title II of its annex that: "child care articles must be made of materials which either not burn under direct action of a flame, a spark or any other potential seat of fire, or are hardly flammable (the flame extinguishes as soon as the fire cause disappears), or, when flammable, burn slowly with a low flame propagation rate" Consequently, the requirements in Clause of this European Standard will have to be supplemented, in France, by the following: "The flame propagation rate of textiles, coated textile supports and plastic coverings shall not exceed 30 mm/s when tested in accordance with EN 71-2:2011, 5.4."
