After the chair mounted seat is set up for normal use in accordance with the manufacturer's instructions, there shall be no accessible openings in mesh that allow the test probe for mesh (4.1) to penetrate up to the 7 mm diameter section, when tested in accordance with 8.2.1.2. The test shall be carried out with the product in any intended position of use. This requirement does not apply to the restraint system. 8.2.1.2 Test method Check whether the 7 mm probe (4.1) with an applied force of up to 30 N, enters 10 mm or more into any accessible completely bounded circular opening in any possible orientation. If the 7 mm probe enters 10 mm or more, then the 12 mm probe (4.1), shall also enter 10 mm or more with an applied force of up to 5 N. Check whether the test probe for mesh (4.1) with an applied force of up to 30 N, penetrates accessible openings in mesh up to the 7 mm diameter section. 8.3 Hazards due to moving parts (see A.4.2) 8.3.1 Requirements for compression points After the chair mounted seat is set up for normal use in accordance with the manufacturer's instructions, there shall be no accessible compression points which can close to less than 12 mm unless they are always less than 3 mm, as the result of: a) the movement of the chair mounted seat; or b) the movement of body weight by the child using the chair mounted seat; or c) the application of an external force (either by another child or, unintentionally, by the carer, or by a powered mechanism). Movement due to elasticity and/or play of materials shall not be considered as a compression hazard. Compression points between the chair mounted seat and the chair are excluded from this requirement. 8.3.2 Requirements for shear points After the chair mounted seat is set up for normal use in accordance with the manufacturer's instructions there shall be no accessible shear points which can close to less than 12 mm, as the result of: a) the movement of the chair mounted seat; or b) the movement of body weight by the child using the chair mounted seat; or SIST EN 16120:2013+A1:2014

Movement due to elasticity and/or play of materials shall not be considered as a shearing hazard. 8.4 Entanglement hazards (see A.4.3) 8.4.1 Requirements Cords, ribbons and similar parts shall have a maximum free length of 220 mm when tested in accordance with 8.4.2. Where cords, ribbons and similar parts are attached to the chair mounted seat together or within 80 mm of each other, any single cord shall have a maximum free length of 220 mm and the combined length from one loose end to the end of another loose end shall be a maximum of 360 mm. Loops shall have a maximum peripheral dimension of 360 mm, when tested in accordance with 8.4.2. Restraint system and chair attachment system are excluded from the above requirements. Monofilament threads shall not be used as cords, ribbons and similar parts, loops or as sewing threads. 8.4.2 Test method The length of a cord, ribbon or similar part is measured from the fixing point on the chair mounted seat to the free end of the cord, ribbon or similar part while a 25 N tensile force is applied. The peripheral dimension of a loop shall be measured while a 25 N tensile force is applied. 8.5 Choking and ingestion hazards (see A.4.4) 8.5.1 Requirements Any component that is considered able to be gripped by a child in accordance with 8.5.2.1 shall be tested in accordance with 8.5.2.2 and 8.5.2.3. Any component or part of a component that is removed shall not fit entirely within the small parts cylinder specified in 4.4. 8.5.2 Test methods 8.5.2.1 Assessment of child’s ability to grip components A component is considered able to be gripped if the child can grip the component between its thumb and forefinger or between its teeth. Where it is difficult to assess whether a child can grip a component, establish whether it can be gripped by inserting the feeler gauge specified in 4.5 once between the component and the underlying layer or body of the chair mounted seat at an angle between 0° and 10° from the surface of the underlying layer or chair mounted seat using a force of (10 ± 1) N. If the gauge can be inserted more than 2 mm, the component is considered able to be gripped by the child. 8.5.2.2 Torque test Apply a torque gradually to the component within a period of 5 s in a clockwise direction until either: SIST EN 16120:2013+A1:2014
EN 16120:2012+A1:2014 (E) 12 a) a rotation of 180° from the original position has been attained; or b) a torque of 0,34 Nm is reached. The maximum rotation or required torque shall be applied for 10 s. The component shall then be allowed to return to a relaxed condition and the procedure repeated in an anticlockwise direction. Where projections, components or assemblies are rigidly mounted on an accessible rod or shaft designed to rotate together with the projections, components or assemblies, during the test the rod or shaft shall be clamped to prevent rotation. If a component attached by a screw thread becomes loosened during application of the required torque, the torque shall continue to be applied until the required torque is exceeded or the component disassembles or it becomes apparent that the component will not disassemble. When using clamps and test equipment, care shall be taken not to damage the attachment mechanism or body of the component. Check whether any component or part of a component that is removed during the test fits wholly in any orientation, without compressing or manipulating it, within the small parts cylinder specified in 4.4. 8.5.2.3 Tensile test Attach a suitable clamp to the component, taking care not to damage the attachment mechanism or body of the component. Fasten the component in a tensile testing machine and apply a tensile force of up to 90 N to the component to be tested. Apply the force gradually within a period of 5 s and maintain it for 10 s. Check whether any component or part of a component that is removed during the test fits wholly in any orientation, without compressing or manipulating it, within the small parts cylinder specified in 4.4. 8.6 Suffocation hazards (see A.4.5) Any plastic covering used for packaging with an area greater than 100 mm x 100 mm shall conform to any of the following requirements: a) have an average sheet thickness of 0,038 mm or more; or b) be perforated with defined holes so that a minimum of 1 % of the area has been removed over any area of 30 mm x 30 mm. Any plastic covering used for packaging with an opening perimeter greater than 360 mm shall not have a drawstring or cord as a means of closing and shall be marked in the official language(s) of the country where the product is sold with the following statement: “Keep plastic covering away from children to avoid suffocation”. The statement may be expressed in different words providing they clearly convey the same warning. Shrunk-on films that are destroyed when the packaging is opened by the user are excluded from these requirements. SIST EN 16120:2013+A1:2014
