EN 14988:2017 (E) 5 1 Scope This European Standard specifies safety requirements for free standing children's high chairs that elevate children to dining table height usually for the purposes of feeding or eating. Children's high chairs are for children up to 3 years of age who are capable of sitting unaided. With the exception of special high chairs for medical purposes, this standard applies to children's high chairs for domestic and non-domestic use. NOTE If a children's high chair has to or can be converted into other functions, additional European Standards may apply. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

line intersection of the seat and the back rest 4 General 4.1 Test conditions The high chair shall be tested as delivered. If the high chair is a knock-down type, it shall be assembled according to the instructions supplied with it. If the instructions allow for different adjustments or configurations of components (e.g. inclination of the backrest, height of the seat, position of the tray, position of castors/wheels, etc.), the most onerous combination shall be used for each test, unless otherwise specified in the test method. Knock-down fittings shall be tightened before testing. Further re-tightening shall not take place. 4.2 Application of forces The forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic force is applied. The tests are described in terms of the application of forces, however masses can be used. The relationship 10 N = 1 kg shall be used for this purpose. 4.3 Tolerances Unless otherwise stated, the following tolerances apply: — Forces: ± 5 % of the nominal force; — Masses: ± 0,5 % of the nominal mass; — Dimensions: ± 1,0 mm of the nominal dimension; — Angles: ± 2° of the nominal angle; — Positioning of loading pads: ± 5 mm. SIST EN 14988:2017



EN 14988:2017 (E) 7 NOTE For the purposes of uncertainty in measurements, test results are not considered to be adversely affected when the above tolerances are met. 4.4 Test sequence The tests in Clause 8 shall be carried out on the same high chair and in the order of the clauses of this standard. 4.5 Determination of the junction line The junction line is shown in Figure 1 below. Where the backrest and the seat do not meet, the junction line is the projection of the backrest onto the seat (see Figure 1).
Key LL junction line 1 backrest 2 seat Figure 1 — Junction line When the seat unit is in the form of a hammock, a theoretical junction line, “LL”, shall be determined as shown in Figure 2. The junction line may vary when the backrest is adjusted in different positions.

EN 14988:2017 (E) 16 8.1.1.2 Incomplete deployment In order to prevent the hazards due to incomplete deployment, the high chair shall fulfil one of the following: a) the weight of the child in the high chair shall act to prevent the folding; or b) at least one locking device shall engage automatically, when the product is ready for use. 8.1.1.3 Unintentional folding of the high chair Unintentional folding of the high chair shall be prevented. This requirement is fulfilled if one of the following conditions is met before and after testing in accordance with 8.1.2.1: a) at least one operating device requires a minimum force of 50 N to activate, with and without test mass A on the seat, or b) folding is only possible if at least one locking mechanism requires the use of a tool, or c) folding is only possible, when two independent operating devices are operated simultaneously, or d) there are two or more automatically engaging locking devices that both cannot be released by one single action, or e) folding of the high chair requires two consecutive actions, the first of which shall be maintained while the second is carried out. 8.1.1.4 Locking mechanism strength When tested in accordance with 8.1.2.2, the high chair shall not fold and the locking mechanism shall remain engaged. 8.1.2 Test methods 8.1.2.1 Durability of the locking mechanism Operate all locking mechanisms 300 times. 8.1.2.2 Strength of the locking mechanism Place the high chair on the floor with the test mass A (5.2) at the centre of the seat. Apply a force of 200 N at the point and in the direction considered most likely for the high chair to fold. If the high chair tends to tilt, secure it in a manner which prevents tilting but not folding. 8.2 Hazards caused by height adjustment 8.2.1 General High chairs in which the seat height cannot be adjusted either due to the construction of the high chair or when the child is inside the high chair are excluded from this requirement. There shall be locking mechanism(s) to prevent the seat unit of a high chair from moving from a higher to a lower position 8.2.2 Incomplete seat height adjustment In order to prevent hazards due to incomplete seat height adjustment, at least one locking device shall engage automatically when the seat is adjusted in height.
